# fastify-totp
A plugin to handle TOTP (e.g. for 2FA)
## Install
```bash
npm i --save fastify-totp
```
## Usage
```js
fastify.register(require('fastify-totp'))
// ...
secret = fastify.totp.generateSecret()
// You should now store secret.ascii in order to verify the TOTP.
const token = req.body.token
isVerified = fastify.totp.verify({ secret: secret.ascii, token })
```
The plugin includes also a facility to generate a **QRCode** that can be used
to quickly configure third-party authenticators (*e.g. Google Authenticator*)
```js
const qrcode = await fastify.totp.generateQRCode({ secret: secret.ascii })
```
