Login

Language: Deutsch · English

Sign in to the server – by password, single sign-on (e.g. Microsoft), anonymously, with mandator selection or biometrically.

HOW-TO USER UPDATED: JUL 2026 APPLIES TO NUCLOS APP 1.0

On this page

Choose a server (see connect a server), enter user name and password, tap Log in. The app keeps the session via a cookie (like the Web Client).

If an SSO service is active on the server, the app offers it as its own login button at start – e.g. Nuclos on Microsoft. Tapping it opens the provider's sign-in page (OAuth2 / OpenID Connect, authorization code grant); after a successful sign-in the app session is authorised – the same principle as in the Web Client.

Signing in via a configured SSO service (here „Nuclos on Microsoft“).

Configured on the server

Which SSO services appear as buttons is configured on the server by administration – see SSO configuration (OAuth2/OIDC, callback URL, user mapping). The user is matched to the Nuclos account by e-mail or username from the ID token.

Flow, WebView and user mapping in detail: Single sign-on (SSO).

If the server allows anonymous access, Explore anonymously appears – ideal to view a demo without credentials.

On mandator-capable Nuclets the app asks, after a successful login, which mandator you want to work in – only then is the session usable (like the Web Client).

If biometric login is enabled for the server, the app signs you in via Face ID / Touch ID – it is offered automatically on launch.

If the server allows self-registration, a link on the login screen leads to account creation.
Forgot username or password? opens the e-mail self-service.
If your password has expired, the app requires a password change before sign-in.

Full details under Account and password.

Right after login the app – like the Web Client – shows confirmation-required notices (e.g. the privacy policy) that must be accepted; declining signs you out immediately. Informational, unread news follow.
