SSO: Authenticate user without credentials from 3rd party application


I wanted to ask if there is a “simple” way to authenticate a user from a 3rd party application?

So I already have a user management in my application and want to login the user in NC without them having to enter the NC credentials.

Something like: The user in my application gets a token or secret or app password e.g. and with this I can obtain a SSO link from NC via API which I redirect the user from by browser application to.

I don’t want to have a shared system like SAML or something similar.

Thx & BR,
