How to enable 2FA on Posteo

← Posteo overview Supported

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.

Step-by-step setup

1
Sign in to Posteo and open your Posteo account security settings.
2
Turn on two-factor authentication and choose the authenticator-app option.
Look for "Authenticator app", "Authentication app", or "TOTP" rather than SMS.
3
Scan the QR code with MS Authenticator App.
Open MS Authenticator App, tap add, and point your camera at the QR code Posteo displays. Can't scan? Enter the setup key manually instead.
4
Enter the 6-digit code to confirm.
Type the code MS Authenticator App generates to verify and link your Posteo account.
5
Save your backup codes.
Store the recovery codes Posteo gives you somewhere safe — you'll need them if you lose your phone.

Menu names on Posteo can change — the official Posteo 2FA documentation ↗ always has the exact, current path.
