feathers-service-verify-reset

Adds user email verification, forgotten password reset, and other capabilities to local feathers-authentication.

Build Status Coverage Status

Deprecated: feathers-service-verify-reset has been moved into Feathers core as feathers-authentication-management for the Auk release.

feathers-authentication-management has important new capabilities. Its API has been rationalized and deprecated features have been removed. Documentation is available at Feathers docs under Authentication, Password Management, Local. (Also available here for now.)

Migration to feathers-authentication-management

  • options.userPropsForShortToken renamed options.identifyUserProps. It contains all fields uniquely identifying the user. These will mainly be communications (email, cellphone, facebook) but also username.

  • The prop names in options.identifyUserProps need to have unique key columns in the DB. This repo uses DB failures to catch duplicate keys, because .verifyChange values makes catching potential duplicates difficult.

  • user item should have a primaryCommunication prop for the notifier.

  • hooks.restrictToVerified renamed hooks.isVerified

  • options.userNotifier renamed options.notifier

  • notifier must return a promise

  • notifier(p1, p2, p3) now, not (p1, p2, p3, newEmail). The requested changes are in .verifyChanges.

  • notifier type emailChange is now identityChange

  • resendVerifySignup no longer allows a string param to be the email

  • verifyReset param actions removed: unique, resend, verify, forgot, reset, password, email

  • options.service added. default '/users'. Read docs on multiple services for further information.

  • service accessed by require(repo-name) now, not require(repo-name).service.

  • hooks still accessed by require('repo-name').hooks.

  • hooks.addVerification no longer has the previous param. Read docs on multiple services for further information. This allows addVerification to be used with multiple instances of authManagement configurations.

  • hooks.addVerification's options.len removed. use options.longTokenLen

  • wrapper sendResetPwd(identifyUser, notifierOptions) now, not (email, notifierOptions)

  • wrapper passwordChange(oldPassword, password, identifyUser) now, not (oldPassword, password, user)

  • wrapper identityChange(password, changesIdentifyUser, identifyUser) now, not emailChange(password, email, user)

  • neither the service nor the wrappers support callbacks. Callbacks for services are being removed from feathers in early 2017 with the Buzzard release.

  • service changed from

    verifyReset.create({
      action: 'passwordChange',
      value: { oldPassword: plainPassword, password: plainNewPassword },
    }, { user: paramsUser }, cb)

to

    verifyReset.create({
      action: 'passwordChange',
      value: { user: { email }, oldPassword: plainPassword, password: plainNewPassword },
    })
  • service changed from
    verifyReset.create({
      action: 'emailChange',
      value: { password: plainPassword, email: newEmail },
    }, { user: paramsUser }, cb)

to

    verifyReset.create({
      action: 'identityChange',
      value: { user: { email }, password: plainPassword, changes: { email, cellphone } },
    })
  • user needs to add these hooks for the verifyReset service, the repo no longer does it automatically:

    for feathers-authenticate < v1.0

    const isAction = (...args) => hook => args.includes(hook.data.action);
    before: {
        create: [
          hooks.iff(isAction('passwordChange', 'emailChange'), auth.verifyToken()),
          hooks.iff(isAction('passwordChange', 'emailChange'), auth.populateUser()),
        ],
    },

or for feathers-authenticate v1.0

    const isAction = (...args) => hook => args.includes(hook.data.action);
    before: {
      create: [
        hooks.iff(isAction('passwordChange', 'emailChange'), auth.hooks.authenticate('jwt')),
        hooks.iff(isAction('passwordChange', 'emailChange'), auth.populateUser()),
      ],
    },

feathers-service-verify-reset features

Capabilities:

  • Checking that values for fields like email and username are unique within users items.
  • Hooks for adding a new user.
  • Send another email address verification notification, routing through your email or SMS transports.
  • Process an email address verification from a URL response.
  • Process an email address verification after an SMS notification.
  • Send a forgotten password reset notification, routing through your email or SMS transports.
  • Process a forgotten password reset from a URL response.
  • Process a forgotten password reset from an SMS notification.
  • Process password change.
  • Process email address change.

User notifications may be sent for:

  • Email addr verification request when a new user is created.
  • Resending a new email addr verification, e.g. previous verification email was lost or is expired.
  • Successful user verification.
  • Sending an email to reset the password when the password is forgotten.
  • Successful password reset for a forgotten password.
  • Manual change of a password.
  • The previous email address is notified of a change of email address.

May be used with

  • feathers-client service calls over websockets or HTTP.
  • Client side wrappers for feathers-client service calls.
  • HTTP POST calls.
  • React's Redux.
  • Vue (docs to do)

A 30-char token is generated suitable for URL responses. (Configurable length.) This may be embedded in URL links sent by email, SMS or social media so that clicking the link starts the email address verification or the password reset.

A 6-digit token is also generated suitable for notification by SMS or social media. (Configurable length, may be alpha-numeric instead.) This may be manually entered in a UI to start the email address verification or the password reset.

The email verification token has a 5-day expiry (configurable), while the password reset has a 2 hour expiry (configurable).

Typically your user notifier refers to a property like user.preferredCommunication: 'email' to determine which transport to use for user notification. However the API allows the UI to be set up to ask the user which transport they prefer this time, when resending a email address verification and sending a forgotten password reset.

The server does not handle any interactions with the user. Leaving it a pure API server, lets it be used with both native and browser clients.

Contents

Code Example

The folder example/ presents a full featured server/browser implementation whose UI lets you exercise the API.

The Service

app.configure(authentication)
  .configure(verifyReset({ options }))
  .configure(user);

options are:

  • userNotifier: function(type, user, notifierOptions, newEmail, cb)
    • type: type of notification
      • 'resendVerifySignup' from resendVerifySignup API call
      • 'verifySignup' from verifySignupLong and verifySignupShort API calls
      • 'sendResetPwd' from sendResetPwd API call
      • 'resetPwd' from resetPwdLong and resetPwdShort API calls
      • 'passwordChange' from passwordChange API call
      • 'emailChange' from emailChange API call
    • user: user's item, minus password.
    • notifierOptions: notifierOptions option from resendVerifySignup and sendResetPwd API calls
    • newEmail: the new email address from emailChange API call
  • longTokenLen: Half the length of the long token. Default is 15, giving 30-char tokens.
  • shortTokenLen: Length of short token. Default is 6.
  • shortTokenDigits: Short token is digits if true, else alphanumeric. Default is true.
  • delay: Duration for sign up email verification token in ms. Default is 5 days.
  • resetDelay: Duration for password reset token in ms. Default is 2 hours.
  • userPropsForShortToken: A 6-digit short token is more susceptible to brute force attack than a 30-char token. Therefore the verifySignupShort and resetPwdShort API calls require the user be identified using a find-query-like object. To prevent this itself from being an attack vector, userPropsForShortToken is an array of valid properties allowed in that query object. The default is ['email']. You may change it to ['email', 'username'] if you want to identify users by {email} or {username} or {email, username}.

The service creates and maintains the following properties in the user item:

  • isVerified: if the user's email addr has been verified (boolean)
  • verifyToken: the 30-char token generated for email addr verification (string)
  • verifyTokenShort: the 6-digit token generated for email addr verification (string)
  • verifyExpires: when the email addr token expire (Date)
  • resetToken: the 30-char token generated for forgotten password reset (string)
  • resetTokenShort: the 6-digit token generated for forgotten password reset (string)
  • resetExpires: when the forgotten password token expire (Date)

The users service is expected to be already configured. Its patch method is used to update the password when needed, therefore patch may not have a auth.hashPassword() hook.

Client

The service may be called on the client using

Using Feathers' method calls

Method calls return a Promise unless a callback is provided.

const verifyReset = app.service('verifyReset');
 
// check props are unique in the users items
verifyReset.create({ action: 'checkUnique',
  value: uniques, // e.g. {email, username}. Props with null or undefined are ignored.
  ownId, // excludes your current user from the search
  meta: { noErrMsg }, // if return an error.message if not unique
}, {}, cb)
 
// resend email verification notification
verifyReset.create({ action: 'resendVerifySignup',
  value: emailOrToken, // email, {email}, {token}
  notifierOptions: {}, // options passed to options1.userNotifier, e.g. {transport: 'sms'}
}, {}, cb)
 
// email addr verification with long token
verifyReset.create({ action: 'verifySignupLong',
  value: token, // compares to .verifyToken
}, {}, cb)
 
// email addr verification with short token
verifyReset.create({ action: 'verifySignupShort',
  value: {
    token, // compares to .verifyTokenShort
    user: {} // identify user, e.g. {email: 'a@a.com'}. See options1.userPropsForShortToken.
  }
}, {}, cb)
 
// send forgotten password notification
verifyReset.create({ action: 'sendResetPwd',
  value: email,
  notifierOptions: {}, // options passed to options1.userNotifier, e.g. {transport: 'sms'}
}, {}, cb)
 
// forgotten password verification with long token
verifyReset.create({ action: 'resetPwdLong',
  value: {
    token, // compares to .resetToken
    password, // new password
  },
}, {}, cb)
 
// forgotten password verification with short token
verifyReset.create({ action: 'resetPwdShort',
  value: {
    token, // compares to .resetTokenShort
    password, // new password
    user: {} // identify user, e.g. {email: 'a@a.com'}. See options1.userPropsForShortToken.
  },
}, {}, cb)
 
// change password
verifyReset.create({ action: 'passwordChange',
  value: {
    oldPassword, // old password for verification
    password, // new password
  },
}, { user }, cb)
 
// change email
verifyReset.create({ action: 'emailChange',
  value: {
    password, // current password for verification
    email, // new email
  },
}, { user }, cb)
 
// Authenticate user and log on if user is verified.
var cbCalled = false;
app.authenticate({ type: 'local', email, password })
  .then((result) => {
    const user = result.data;
    if (!user || !user.isVerified) {
      app.logout();
      cb(new Error(user ? 'User\'s email is not verified.' : 'No user returned.'));
      return;
    }
    cbCalled = true;
    cb(null, user);
  })
  .catch((err) => {
    if (!cbCalled) { cb(err); } // ignore throws from .then( cb(null, user) )
  });

Provided service wrappers

The wrappers return a Promise unless a callback is provided. See example/ for a working example of wrapper usage.

```javascript`

or import VerifyRest from 'feathers-service-verify-reset/lib/client';

const app = feathers() ... const verifyReset = new VerifyReset(app);

// check props are unique in the users items verifyReset.checkUnique(uniques, ownId, ifErrMsg, cb)

// resend email verification notification verifyReset.resendVerifySignup(emailOrToken, notifierOptions, cb)

// email addr verification with long token verifyReset.verifySignupLong(token, cb)

// email addr verification with short token verifyReset.verifySignupShort(token, userFind, cb)

// send forgotten password notification verifyReset.sendResetPwd(email, notifierOptions, cb)

// forgotten password verification with long token verifyReset.resetPwdLong(token, password, cb)

// forgotten password verification with short token verifyReset.resetPwdShort(token, userFind, password, cb)

// change password verifyReset.passwordChange(oldPassword, password, user, cb)

// change email verifyReset.emailChange(password, email, user, cb)

// Authenticate user and log on if user is verified. verifyReset.authenticate(email, password, cb)


### <a name="fetch"> HTTP fetch (docs to complete)

```javascript
// check props are unique in the users items
// Set params just like [Feathers method calls.](#methods)
fetch('/verifyReset', {
  method: 'POST', headers: { Accept: 'application/json' },
  body: JSON.stringify({ action: 'checkUnique', value: uniques, ownId, meta: { noErrMsg } })
})
  .then(data => { ... }).catch(err => { ... });

You will want to refer to authenticating over HTTP.

React's Redux

See feathers-reduxify-services for information about state, etc. See feathers-starter-react-redux-login-roles for a working example.

Dispatching services

import feathers from 'feathers-client';
import reduxifyServices, { getServicesStatus } from 'feathers-reduxify-services';
const app = feathers().configure(feathers.socketio(socket)).configure(feathers.hooks());
const services = reduxifyServices(app, ['users', 'verifyReset', ...]);
...
// hook up Redux reducers
export default combineReducers({
  users: services.users.reducer,
  verifyReset: services.verifyReset.reducer,
});
...
 
// email addr verification with long token
// Feathers is now 100% compatible with Redux. Use just like [Feathers method calls.](#methods)
store.dispatch(services.verifyReset.create({ action: 'verifySignupLong',
    value: token, // compares to .verifyToken
  }, {})
);

Dispatching authentication. User must be verified to sign in.

const reduxifyAuthentication = require('feathers-reduxify-authentication');
const signin = reduxifyAuthentication(app, { isUserAuthorized: (user) => user.isVerified });
 
// Sign in with the JWT currently in localStorage
if (localStorage['feathers-jwt']) {
  store.dispatch(signin.authenticate()).catch(err => { ... });
}
 
// Sign in with credentials
store.dispatch(signin.authenticate({ type: 'local', email, password }))
  .then(() => { ... )
  .catch(err => { ... });

Vue 2.0 (docs todo)

Hooks

The service does not itself handle creation of a new user account nor the sending of the initial email verification request. Instead hooks are provided for you to use with the users service create method.

const verifyHooks = require('feathers-service-verify-reset').verifyResetHooks;
// users service
module.exports.before = {
  create: [
    auth.hashPassword(),
    verifyHooks.addVerification() // adds .isVerified, .verifyExpires, .verifyToken props
  ]
};
module.exports.after = {
  create: [
    hooks.remove('password'),
    aHookToEmailYourVerification(),
    verifyHooks.removeVerification() // removes verification/reset fields other than .isVerified
  ]
};

A hook is provided to ensure the user's email addr is verified:

const auth = require('feathers-authentication').hooks;
const verify = require('feathers-service-verify-reset').hooks;
export.before = {
  create: [
    auth.verifyToken(),
    auth.populateUser(),
    auth.restrictToAuthenticated(),
    verify.restrictToVerified()
  ]
};

An email to verify the user's email addr can be sent when user if created on the server, e.g. example/src/services/user/hooks/index:

Database

The service adds the following optional properties to the user item. You should add them to your user model if your database uses models.

{
  isVerified: { type: Boolean },
  verifyToken: { type: String },
  verifyExpires: { type: Date }, // or a long integer
  resetToken: { type: String },
  resetExpires: { type: Date }, // or a long integer
}

Routing

The client handles all interactions with the user. Therefore the server must serve the client app when, for example, a URL link is followed for email addr verification. The client must do some routing based on the path in the link.

Assume you have sent the email link: http://localhost:3030/socket/verify/12b827994bb59cacce47978567989e

The server serves the client app on /socket:

// Express-like middleware provided by Feathersjs.
app.use('/', serveStatic(app.get('public')))
   .use('/socket', (req, res) => {
    res.sendFile(path.resolve(__dirname, '..', 'public', 'socket.html')); // serve the client
  })

The client then routes itself based on the URL. You will likely use you favorite client-side router, but a primitive routing would be:

const [leader, provider, action, slug] = window.location.pathname.split('/');
 
switch (action) {
  case 'verify':
    verifySignUp(slug);
    break;
  case 'reset':
    resetPassword(slug);
    break;
  default:
    // normal app startup
}

Security

  • The user must be identified when the short token is used, making the short token less appealing as an attack vector.
  • The long and short tokens are erased on successful verification and password reset attempts. New tokens must be acquired for another attempt.
  • API params are verified to be strings. If the param is an object, the values of its props are verified to be strings.
  • options1.userPropsForShortToken restricts the prop names allowed in param objects.

Configurable

The length of the "30-char" token is configurable. The length of the "6-digit" token is configurable. It may also be configured as alphanumeric.

Migration from 0.8.0

A few changes are needed to migrate to 1.0.0. Names were standardized throughout the new version and these had to be changed.

options1.userNotifier signature
  was (type, user1, params, cb)
  now (type, user1, notifierOptions, newEmail, cb)
options1.userNotifier param 'type'
  'resend'   now 'resendVerifySignup'
  'verify'   now 'verifySignup'
  'forgot'   now 'sendResetPwd'
  'reset'    now 'resetPwd'
  'password' now 'passwordChange'
  'email'    now 'emailChange'
 
Error messages used to return
  new errors.BadRequest('Password is incorrect.',
    { errors: { password: 'Password is incorrect.' } })
This was hacky although convenient if the names matched your UI. Now they return
  new errors.BadRequest('Password is incorrect.',
    { errors: { password: 'Password is incorrect.', $className: 'badParams' } })
or even
  new errors.BadRequest('Password is incorrect.',
    { errors: { $className: 'badParams' } })
Set your local UI errors based on the $className value.
 
The following are deprecated but remain working. They will be removed in the future.
options1
  emailer    uses options1.userNotifier
API param 'action'
  'unique'   uses 'checkUnique'
  'resend'   uses 'resendVerifySignup'
  'verify'   uses 'verifySignupLong'
  'forgot'   uses 'sendResetPwd'
  'reset'    uses 'resetPwdLong'
  'password' uses 'passwordChange'
  'email'    uses 'emailChange'
client wrapper
  .unique            uses .checkUnique
  .verifySignUp      uses .verifySignupLong
  .sendResetPassword uses .sendResetPwd
  .saveResetPassword uses .resetPwdLong
  .changePassword    uses .passwordChange
  .changeEmail       uses .emailChange
 
The service now uses the route /verifyreset rather than /verifyReset/:action/:value

Motivation

Email addr verification and handling forgotten passwords are common features these days. This package adds that functionality to Feathersjs.

Install package

Install Nodejs.

Run npm install feathers-service-verify-reset --save in your project folder.

You can then require the utilities.

/src on GitHub contains the ES6 source. It will run on Node 6+ without transpiling.

Install and run example

cd example

npm install

npm start

Point browser to localhost:3030/socket for the socketio client, to localhost:3030/rest for the rest client.

The two clients differ only in their how they configure feathers-client.

feathers-starter-react-redux-login-roles is a full-featured example of using this repo with React and Redux.

Tests

npm test to transpile to ES5 code, eslint and then run tests on Nodejs 6+.
