What would you like to be added:

Based on unoplatform/uno#18410, there was an internal discussion that it would be nice, if we added similar functionality directly in Toolkit/Wizard.

Why is this needed:

Would be a nice feature to have and it would make the development of many apps much easier.

For which Platform:

• WebAssembly
• Android
• iOS
• macOS (AppKit)
• Mac Catalyst
• Skia
  • WPF
  • GTK (Linux)
  • Linux Framebuffer
  • Tizen
• Windows

Is this toolkit or rather a Extensions Authentication feature 🤔

Is this toolkit or rather a Extensions Authentication feature 🤔

Yes, this would make most sense as part of Uno Extensions Authentication. Though you should be able to do this individually using the OIDC extensions I believe? Transferring to Extensions

Although we could have platform specifics for integrations directly with Android/iOS for Google/Apple sign-ins
