How do I set up two-factor sign-in?
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 two-factor sign-in you need a six-digit code from an authenticator app on your phone as well as your password when you sign in. You set it up in your account menu at the bottom left. It's only on once you've saved your 10 recovery codes and clicked Fertig (done). An admin can require it for all members of your company under Einstellungen (settings) in the Mitglieder (members) tab.
How it works
- Open your account menu at the bottom left and click Zwei-Faktor-Anmeldung (two-factor sign-in).
- Scan the QR code with your authenticator app, such as Google Authenticator or 1Password.
- Enter the six-digit code your app is now showing.
- Save your 10 recovery codes in a safe place with Kopieren (copy) or Herunterladen (download).
- Tick Ich habe die Codes sicher gespeichert (I've saved the codes safely) and click Fertig.
Example: Two-factor sign-in on a laptop
On 27 October 2026 you set up two-factor sign-in on your laptop. The next time you sign in, you enter your password and the code from the app. Below the code field, „Diesem Gerät 30 Tage vertrauen“ (trust this device for 30 days) is already ticked. If you leave it ticked, MargenOptimierer won't ask for the code on this laptop for 30 days.
When you don't have your phone
Phone not with you or lost
When you sign in, click Wiederherstellungscode verwenden (use recovery code) and enter one of your codes. Each code works once. A notice at the top of the page then shows how many codes you have left. If you've lost your phone, click App neu einrichten (set up app again) in that notice and connect the app on your new phone.
Phone and codes lost
Ask an admin of your company to reset your two-factor sign-in. The admin finds Zwei-Faktor zurücksetzen (reset two-factor) in the Mitglieder tab, in the menu in your row. This only works if the admin has set up two-factor sign-in themselves, and they confirm with the code from their app. No admin can reset the owner's two-factor sign-in. If you're the owner or there's no other admin, write to info@margenoptimierer.de from the email address you sign in with.
Requiring it for all members
Under Einstellungen in the Mitglieder tab, an admin turns on the Zwei-Faktor-Anmeldung für alle verlangen (require two-factor sign-in for everyone) switch. Anyone who hasn't set it up yet has to do so as soon as they open the next page. Nobody can then turn it off for themselves. The Zwei-Faktor (two-factor) column for the members shows who has set it up.
