Each YubiKey/Security Key with a FIDO2 application comes with a pre-defined AAGUID that is unique to specific firmware and form-factor combinations. It is sometimes important to know what the AAGUID is of the YubiKey that you are holding in your hand - especially if you are using an identity provider that is configured to filter security keys based on their AAGUID value. If you need to get this information, insert your YubiKey, click Retrieve AAGUID* below, and follow the prompts.
* This process will not save a useable credential to your YubiKey
For more information about various AAGUID values of Yubico's products, refer to YubiKey hardware FIDO2 AAGUIDs.
