    totp-generator lets you generate TOTP tokens from a TOTP key

    How to use

    const totp = require("totp-generator");
    // Keys provided must be base32 strings, ie. only containing characters matching (A-Z, 2-7, =).
    const token = totp("JBSWY3DPEHPK3PXP");
    console.log(token); // prints a 6-digit time-based token based on provided key and current time

    Default token settings

    • SHA-1
    • 30-second epoch interval
    • 6-digit tokens

    Custom token settings

    Settings can be provided as an optional second parameter:

    const totp = require("totp-generator");
    const token = totp("JBSWY3DPEHPK3PXP", { digits: 8 });
    console.log(token); // prints an 8-digit token
    const token = totp("JBSWY3DPEHPK3PXP", { algorithm: "SHA-512" });
    console.log(token); // prints a token created using a different algorithm
    const token = totp("JBSWY3DPEHPK3PXP", { period: 60 });
    console.log(token); // prints a token using a 60-second epoch interval
    const token = totp("JBSWY3DPEHPK3PXP", { timestamp: 1465324707000 });
    console.log(token); // prints a token for given time
    const token = totp("JBSWY3DPEHPK3PXP", {
    	digits: 8,
    	algorithm: "SHA-512",
    	period: 60,
    	timestamp: 1465324707000,
    console.log(token); // prints a token using all custom settings combined
