Troubleshooting and Tools
Troubleshooting
The primary source for troubleshooting tips is the FAQ on the YubiKey Bio Series setup page.
| Fingerprint: | If the YubiKey cannot match fingerprint to template three times in a row, fingerprint recognition is blocked. The YubiKey Bio falls back to PIN. |
|---|---|
| PIN: | If you enter the wrong PIN eight times in a row, the YubiKey FIDO2 application will be locked, which means it cannot communicate with you or with any site or service. It indicates the blocked state by flashing its amber LED slowly and continuously. In order to restore this functionality, the FIDO2 application must be reset. For more details, see FIDO2 PIN. |
| Unblock: | Unblock the YubiKey Bio’s biometric function (its ability to read fingerprints) by going to the unblocking FAQ on the YubiKey Bio start page. Otherwise you can use any of the other methods given in Tools. |
| Reset: | You can also reset it, but doing so erases all the discoverable credentials on it, setting it back to factory defaults. See Resetting Your YubiKey Bio with the Yubico Authenticator for Desktop. |
