User login hook?

I cannot use the Panel for my project (different users has different privileges and I don’t want one user can edit the posts of another user), but I’d like to use the standard login form.

So - is there any hook available on the user login event?
Any other suggestions considering my use case?

Thank you

Take a look at the new Cookbook section of the docs https://getkirby.com/docs/cookbook/authentication.

Otherwise I have created a customized panel with some kind of user rights (different user groups can only see and edit special pages (+ subpages of them). You can find it in the ferature/userrights branch of my panel fork over here: https://github.com/jbeyerstedt/panel/tree/feature/userrights (see the gist with a sample config in the repo description).
This repo is currently maintained with every new version of the panel, but I can not guarantee that it will work in other use cases.

thanks @jbeyerstedt the cookbook saved my day
