If passkey creation fails on your Samsung Galaxy A53 5G, it is likely due to a stuck Credential Manager, outdated Google Play Services, or missing screen lock settings. Fix this by updating your phone, clearing Google Play Services cache, ensuring you have a secure screen lock (PIN/Fingerprint) enabled, and using Chrome.

Here are the specific troubleshooting steps for your A53:
This video explains how to set up and use passkeys on your Android device:
Ensure Screen Lock is Active: Passkeys require a secure lock (PIN, pattern, or fingerprint) to work. If you recently removed your lock, passkeys will not function.
Clear Credential Manager Cache: Go to Settings > Apps > Google Play Services > Storage > Clear Cache.
Update Google Chrome: Make sure you are using the latest version of Chrome, as older versions may not support the necessary WebAuthn features.
Check Samsung Pass: If you are trying to save to Samsung Pass, ensure the app is updated and the service is enabled in settings.
Use the Right Method: If prompted to "Use another device" via QR code, try selecting "This device" instead to create the passkey directly on your A53.
Reboot: A simple restart can fix frozen authentication pop-ups.
