@berlinsms/react-twofa-component is a TypeScript React Component to validate Phonenumbers or E-Mail Adresses using a Two Factor Authentification.
npm -i @berlinsms/react-twofa-componentThe Mail and SMS verification are now located in the same Component. The Component will automaticly switch to the previously selected verificationmehtod (https://twofa.berlinsms.de/keygen).
import {TwoFA} from '@berlinsms/react-twofa-component';
// Minimal implementation:
<TwoFA
bsmsSitekey = {"your sitekey"}
/>
// Complete implementation:
<TwoFA
ref={twoFARef}
bsmsSitekey = {"your sitekey"}
onError = {TwoFAonError}
onVerify = {TwoFAonVerify}
onExpire = {TwoFAonExpire}
/>To use this Component you have to configure your settings on https://twofa.berlinsms.de/keygen
By using the required bsmsSitekey Parameter your site will be validated and load all predefined settings. This Component will request your selected verification method and automaticly load the predefined configuration. Therefore it is not necessary to switch manualy between Mail-verification and SMS-verification. These settings also contain your captcha Type and Key.
The ref Parameter helps the user to keep track of the current object. By creating a reference additional informations can be gathers as for example the states. All of the state codes can be seen in the TwoFATypes.tsx file and are described below.
The onError function is called if an Error occures. This might be for example that component cant reach the API or the user has no more tries left. The function requires a error: string parameter, that describes the error.
The onVerify function is called when the user correctly entered the code and now your own webserver can validate the user request. The token (string) Parameter is required and is needed for the final verification. Optionally the inserted Two Factor Code can be requested: code?: string
The Language can be set by using the optional Parameter: bsmsLanguage. (bsmsLanguage?: "Eng" | "Ger";) This Parameter takes the values "Eng" or "Ger" (German). Default Language is German.
OnExpire is called when the time to fill out the component is run out. This function is still under development.
