App

Is your suggested feature related to a problem? Please describe.

When signing in to anything within the modrinth app, it's a huge inconvenience.

This is because it uses the built-in web view to open a separate window, and not the system's default browser. It prevents me from making use of site cookies for things like google oauth, as well as my password manager.

Describe the solution you'd like

Open these prompts in the system default browser instead.

Describe alternatives you've considered

Adding an option to the settings to switch between the existing functionality and my suggested functionality.

I believe the Microsoft login used to be the case, I'm not sure why they changed it
