Goal

Improve the IdP login and registration experience to match NSS (Node Solid Server) functionality.

Changes

Login Page

• Show which app is requesting access
• Use username instead of email (email is optional, internally username@jss)
• Add "Register" link for new users

Registration Page

• Create registration form (/idp/register)
• Username + password fields
• Auto-create pod on registration
• Redirect to login after registration

Account System

• Support username-based authentication
• Username index for fast lookup
• Email is optional (defaults to username@jss internally)
• Login accepts username or email

Technical Details

• Registration creates both account and pod in one step
• No email verification required (like NSS)
• No password minimum (for testing purposes)
• Username: lowercase alphanumeric only
