Email login still shown on Portal when only Discord auth is enabled

[hugoheml]

Hey,
When I enable only Discord authentication for the Portal and disable password authentication, the email/password login option is still displayed on the Portal login page.
Since password authentication is turned off, this option shouldn't appear — only the Discord login should be available.

Steps to reproduce:

1. Enable Discord authentication for the Portal
2. Disable password authentication
3. Open the Portal login page

Expected behavior: Only the Discord login option is shown.
Actual behavior: The email/password login is still offered.

Thanks!
