Troubleshoot signing in with a passkey

"iPhone, iPad, or Android device" QR code not shown when signing in on Windows 

There are three main reasons why a QR code for your mobile device does not show when trying to sign in with a passkey:

1. Bluetooth is not enabled. Bluetooth must be enabled on both devices: the one on which you are signing in and the device that contains your passkey.

2. Your authenticating devices must be in range and connected to the internet. They do not need to be on the same network.

3. Authenticating with another device using Bluetooth may not be allowed by your organization. Admins read how to configure passkeys.

"We couldn’t sign you in" when using an Android Work profile

If you see the message "We couldn’t sign you in" when trying to sign in on your Android device, it could be that your passkey is saved in a different profile. 

If your passkey for a work account was created using a camera or authenticator app in your Personal profile, you will need to recreate a passkey in your Work profile.

"Sign in another way. We couldn't use your device to verify your identity" message

If you try to sign in using a passkey and see the error message "We couldn't use your device to verify your identity," it means the passkey is no longer valid on that device.

To sign in, select one of the alternatives offered, then check your account for any passkeys that no longer apply and delete them.

"This passkey can no longer be used" message

If you see a message saying your passkey is not found, can no longer be used, or is no longer valid, it could be because the passkey has been deleted from your account.

To fix the issue:

1. Check the authenticator app on your mobile device for any passkeys that no longer apply and delete them.

2. Set up a new passkey.

You got a new device

When you get a new device, you may need to set up a new passkey with your new device. Once completed, you can safely remove any old passkeys from your account.

1. Set up a new passkey first.

2. Check your account for any passkeys that no longer apply and delete them.
