Many users just want to quickly try the app right after installing it, and they don’t have the patience to verify their email first.
In most mobile apps, it’s common to allow immediate login after registration, and only require email verification later — for example, before using payment or posting features.

This PR adds an option to disable mandatory email verification, so users can access the app right away.
Developers can still prompt for verification later when needed.

Why:

Faster onboarding for mobile users

Reduces drop-off during registration

Keeps flexibility for apps that need verification later
