To set up a passkey on your Android phone, please check the following steps in your device settings:
Search for “Screen lock / Device protection” and make sure that a screen lock method such as a pattern, PIN, or password is enabled. If not, please activate one.
The passkey on Android devices is usually stored in the Google Password Manager, provided it is set up as the default option.
If you use a different password manager (e.g., Samsung Pass, Bitwarden, etc.), the passkey can be stored there instead.
Example using a Samsung device:
Settings → General management → Passwords, passkeys and autofill → Select preferred service
Set preferred service
In this menu, you can choose which service to use (e.g., Google or Samsung Pass).
If you want to use the Google Password Manager, select Google as the preferred service.
Please contact the support team if you would like detailed instructions for your specific Android device.
