Unironically this…

Passkeys don’t work on my rooted device - they seemingly set up correctly, but sites like GH claim your device passkey doesn’t exist when you try to actually login. When you go to the affected site’s account settings to add the device as a passkey again, an error of some kind claims the passkey already exists 🤷‍♂️

Deleting/re-adding has no effect. Using FF with device biometric passkey auth
