Enable two-factor authentication (2FA) whenever possible! With 2FA, signing in takes something you know (password) AND something you have (like a code to your phone). This adds a much needed extra layer of security to keep your accounts secure.

#2factorauthetification ist schon was feines. Nicht aber, wenn man durch einen Syncfehler und eigene Blödheit alle Tokens aus der Authenticator-App verliert. Der Nachmittag ist gerettet. 🤦

Kleiner Tipp: Haltet immer eure Backup-Codes griffbereit.

TL:DR
Google Authenticator is adding Account syncing of OTP/2FA codes. The problem is this Sync is not end-to-end Encrypted.

Also Google Authenticator QR codes contain website & account names.

Meaning if someone intercepts the data in transit, or gets access to your google account, they have full access to all your 2FA.
