QR Code
π¨βπΌ Now that the
2fa-verify verification in the database, we can update the
loader for to load the
user's 2fa-verify verification and generate a Auth URI and QR code for the
verification.import { getTOTPAuthUri, generateTOTP } from '@epic-web/totp'
const { secret, period, digits, algorithm } = generateTOTP()
// save this to the database...
// then generate the Auth Uri:
const otpUri = getTOTPAuthUri({
period,
digits,
algorithm,
secret,
accountName: user.email,
issuer: 'Your App Name',
})
Most phones have the ability to scan the QR code and automatically add the
verification to the phone:
import * as QRCode from 'qrcode'
// ...
const qrCode = await QRCode.toDataURL(otpUri)
// ...
<img src={qrCode} />
If the phone does not have this ability, the user
can manually enter the
otpUri into their authenticator app.We're not going to get to the scanning part quite yet though. You just need
to update the loader to handle getting the verification and generating the Auth
URI.
