YubiKey 5Ci U2F Chrome Based Browsers Registration

Applicable Products


When using the YubiKey 5Ci with USB-C, some services do not recognize the key and can’t be used for registration using an affected browser and service combination.  Authentication will work if the YubiKey 5Ci has been registered via a different Browser.  


Affected browsers include: 

  • Chrome
  • Brave
  • Opera
  • Any Chromium based browser


Affected services include: 

  • Facebook
  • GitHub


Yubico is currently working with affected browsers and services to fix the issue.    


As only key registration is affected, please use Firefox to register the YubiKey 5Ci for these services.  Authentication will work on the affected browsers after the key has been registered with the account.
