Posteo 2FA: How to Set Up an Authenticator App
Posteo lets you secure your account with an authenticator app. With 2FA on, each login needs a fresh 6-digit code, keeping your Posteo account safe even if your password leaks.
Your Posteo inbox is the master key to your other accounts — attackers use it to reset passwords everywhere. Posteo secures sign-ins with an authenticator app — set it up once and you're protected on every login.

Save a way to recover your account.
If Posteo shows backup or recovery codes, store them somewhere safe, away from your phone. If it doesn't, check how Posteo recovers accounts (support, an admin, or another sign-in method) before you need it.
Menu names on Posteo can change — the official Posteo 2FA documentation ↗ always has the exact, current path.
How to recover your Posteo account
If you lose access to your authenticator and Posteo gave you backup or recovery codes when you turned on 2FA, sign in with one of them; keep them somewhere safe, away from your phone. Not every service issues codes. If Posteo doesn't, or you didn't save them, use Posteo's account-recovery or support process (or ask your admin, for a work account) to get back in.
