For iOS devices, your device must be running at least iOS 16 or iPadOS 16. Additionally, ensure that iCloud Keychain is activated on your device.
Android devices must run at least Android 9 (Pie). To create and use passkeys, make sure that your biometric sensor (such as a fingerprint scanner or facial recognition) or a secure screen lock method (like a PIN or pattern) is enabled. You will also need a compatible browser installed.
Please note that Huawei’s HarmonyOS currently does not support passkeys.
