Sign in once to all your FSG applications. Use passwordless sign-in with a passkey, or a password together with a second factor of your choice.
Passkeys work on almost every current device: Face ID and Touch ID on iOS and macOS, Windows Hello on Windows, and the equivalent on Android. Hardware security keys (FIDO2) are an affordable option as well.
Staying signed in: Tick "Remember me" on your own device to stay signed in longer (up to 14 days; otherwise about 4–8 hours). Note that signing out of an app such as Webmail, Zammad or Cloud also ends your single sign-on in that browser.
You can find more detailed information in the orga section of the FSG website. If you have any questions, please contact website support via the link on your FSG website account page.
