To activate and **configure two-factor authentication** for OpenProject, navigate to -> *Administration* -> *Authentication* and choose -> *two-factor authentication*.

You can configure the following options:

2. **Remember 2FA login for a given number of days**, e.g. 30 days.
3. Press the blue **Apply** button to save your changes.
