What is a recovery code?
Last updated: 31 October 2026 · The MargenOptimierer app is in German. Button and menu names are shown exactly as you see them, with the English meaning in brackets.
A recovery code is a backup code you sign in with when you don't have your phone.
You get 10 of them when you set up two-factor sign-in. Each code works only once. Keep them somewhere safe, for example as a file using the Herunterladen (download) button.
Example: Three sign-ins without a phone
Say you sign in 3 times without a phone. You then have 7 of the 10 codes left.
What else counts for recovery codes
How to sign in with one
On the Code eingeben (enter code) page, click Wiederherstellungscode verwenden (use recovery code) and enter one of your codes. A notice at the top then tells you how many codes you have left.
Lost your phone
In the notice after you sign in, click App neu einrichten (set up app again) and connect the authenticator app on your new phone. You get 10 new codes, and the old ones stop working. The notice only stays until you reload the page. If you missed it, sign out and sign in again with a recovery code.
New codes while you still have your phone
In your account menu at the bottom left, click Zwei-Faktor-Anmeldung (two-factor sign-in) and then Neue Wiederherstellungscodes (new recovery codes). You enter the current code from the app for this. The old codes then stop working.
