  6. Enter the PIN again in the Confirm PIN section and click Set PIN to save it.
  7. When a PIN is saved, a label will appear near the FIDO2 PIN option stating as such and the available retries before the key wipes itself.
  8. If a user does not remember their PIN, select the Reset option to the right. This will wipe the key of the previous information. Any authorizations dependent upon this key must be reconfigured with the key's new settings.
