A user gateway. I need a product that can help me process user registration, login, session and other user identity logic. Than I can add my own user experiences using programming languages. The present user processing tools are too complicated and makes non sense.

seems great, but how to use it in other programming language? How to add my backend logic?

Auth0 might be a good fit for you. Not affiliated, just a fan.

[du_bing]

thanks, checked it before, still complicated somehow

Check out AWS Cognito

[du_bing]

[mister_hn]

why not using WebAuthn? https://webauthn.io/

On GCP, maybe firebase auth: https://firebase.google.com/docs/auth

Definitely this.

Edit: let me expand on why. You get to take advantage of the power of all of google's security team, with a nice clean simple api, great client libraries and excellent documentation.

There is also some cool features like the ability to tie custom data to a user (claims) and integrate with the realtime datastore for immediate notifications about changes to the user.

There is some great examples on how to implement this in the docs. I implemented this in my own app so that when I enable a 'role' for a user, the app literally updates (in both a Flutter mobile and React webapp) without even a refresh of the window. Pretty epic UX and super painless to implement.

Oh and it is effectively free.
