Testing two factor authentication
using the TOTP algorithm

Scanning the barcode into a 2FA authenticator (such as Google Authenticator (Android; iOS) should produce the six digit number shown.

Key:
2ZZGGMQ4MBKNMLSZP5QGKZCPT5ZQJZKM
(digits shown in in red to distinguish them)

Should produce passcode:
262122

(Normally the app wanting authentication wouldn't show you this number, and the authenticator wouldn't show you the key.)

new key

Your key from another app: (spaces ignored)

Thanks RobThree for the library that produces this.
