What do I do if I've forgotten my password?
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.
With Passwort vergessen? (forgot password?) on the sign-in page you request a link by email. The email says that the link works for one hour and only once. Through it you set a new password and are then signed in. You don't need your old password for this.
How it works
- On the sign-in page, click Passwort vergessen?
- Enter your email address and click Link zum Zurücksetzen senden (send reset link).
- In the email, click „Neues Passwort festlegen“ (set new password).
- Enter the new password twice, with at least 8 characters.
- Click Passwort speichern (save password).
Example: A link that works for one hour
If you request the link at 14:00, the email says it works until 15:00. If no email arrives, look in your spam folder first. You can request a new email one minute later, so from 14:01.
When the link doesn't help
No email arrives at all
For security reasons, the page doesn't say whether an account exists for the address. So check whether you registered with exactly this address.
The link no longer works
If the link has expired or has already been used, a page opens with the button Neuen Link anfordern (request new link). Click it and request a new email.
You use two-factor sign-in
After you click the link, MargenOptimierer first asks for the code from your authenticator app. You then set the new password. If you no longer have the phone with the app, use one of your recovery codes. What to do without a phone and codes is covered in How do I set up two-factor sign-in?
