Scanning the barcode into a 2FA authenticator (such as Google Authenticator (Android; iOS) should produce the six digit number shown.
Key:
FRTPBCNBOBIPBRHXAMR4O2LAC6RXRL5X
(digits shown in in red to distinguish them)
Should produce passcode:
572867
(Normally the app wanting authentication wouldn't show you this number, and the authenticator wouldn't show you the key.)
Thanks RobThree for the library that produces this.
