Implementation of two-factor authentication in Node, made simple.
npm install 2fa-plusImplementation of two-factor authentication in Node, made simple.
Credit for original implementation on which this has been abstracted from goes to node-2fa - Jeremy Scalpello.
This has been reworked from the ground up to:
- Not be reliant on Google Charts for QR code generation, and instead return a base64-png image.
- Full typescript support.
---
There are a number of applications which support 2-Factor Authentication, namely
- Authy iPhone | Android | Chrome | Linux | OS X
- Google Authenticator iPhone | Android
- Microsoft Authenticator iPhone | Android
This module uses notp which implements TOTP (RFC 6238)
(the _Authenticator_ standard), which is based on HOTP (RFC 4226)
to provide codes that are exactly compatible with all other _Authenticator_ apps and services that use them.
Usage
=====
``bash`
npm install 2fa-plus --save
`ts
import { generateSecret } from "2fa-plus";
const secret = generateSecret('Name', 'account@demo.com');
// output: { secret, uri, qr }
`
`ts
import { generateToken } from "2fa-plus";
const token = generateToken(secret.secret);
// output: token
`
`ts
import { verifyToken } from "2fa-plus";
const isValid = verifyToken(secret, token);
// output: true/false
