What is 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.
Two-factor sign-in means you enter a code from your phone as well as your password when you sign in.
An authenticator app shows the code, and it changes every 30 seconds. Anyone who only knows your password can't get into your account this way. Every member of your company sets up two-factor sign-in for themselves.
Example: Signing in with password and code
Say you enter the password and then the code 482 913 that the app on the phone is showing. If you leave Diesem Gerät 30 Tage vertrauen (trust this device for 30 days) ticked below it, MargenOptimierer won't ask for the code on this device for 30 days.
What else matters for two-factor sign-in
Phone not with you
Without your phone you sign in with a recovery code. You get these codes when you set up two-factor sign-in.
Requiring it for all members
Any admin, including the owner, can require two-factor sign-in for all members. To do this, the admin turns on the Zwei-Faktor-Anmeldung für alle verlangen (require two-factor sign-in for everyone) switch under Einstellungen (settings) in the Mitglieder (members) tab. This only works once the admin has set it up themselves. Anyone who doesn't have it yet then has to set it up before they can keep working.
