I don't get how https://nsec.app can be used by non-tech users:
When you have an account on there, you go to use.nsec.app and you'd like to add an app.
when you select one, you just go to the homepage of that project,... 
Then you install/visit that app. (let's say https://flycat.club/ )
 (any app has the same issue)
Then you log in, but you can't use the bunker-id of nsec.app anywhere in these apps.
I really don't get how this can be made this complicated and unusable.
