If you're asked to scan a QR code even when using your original device and Apple ID, it may be because your iOS version is outdated and doesn't support the passkey feature.
To resolve this, please update your iPhone to the latest version of iOS. Once updated, you'll be able to complete the verification process smoothly.
Checklist
- Why can't I verify my passkey with my original device and Apple ID?
- How do I log in with passkey if I've switched to a new iPhone?
- If you've changed devices, you can still log in by scanning the QR code using a device that supports iOS 18 or above, or any other compatible device.
- I updated to iOS 18 but can't create a passkey. What should I do?
- Why does it say "No passkey found" during verification?
- To continue, tap Use another device and scan the QR code with the device where your passkey was originally set up.
- Does Android support fingerprint login for passkey?
- What if I receive a message saying passkeys aren't supported in my region?
- Is setting up a passkey required?
- Passkey setup is optional but highly recommended. Using a passkey strengthens your account security and allows you to log in without needing a password.
- I updated the app but can't verify my passkey. What should I do?
- What if I see a pop-up notification saying passkeys aren't supported in my region when logging in?
Notes
When setting up a new passkey, we recommend keeping your old device nearby. With Bluetooth enabled on both devices, scan the QR code from your old device to authorize and complete the setup.
If you're unable to create or use a passkey after upgrading to iOS 18, it's possible that the built-in Passwords app on your Apple device was deleted or is not functioning properly.
To fix this:
Make sure your device is running iOS 18 or later
