Ok, I think when user join Primal, should have two options. 

1- The user create an account with Primal and add email and password. 

2- User create an account without email and password, just like today, with Nsec.

 

 Amber is the solution, it's already built and works 

 I see the biggest issue as a noob is that the distro don’t request both nsec and npub for start a login
