Need help, can't access help, big probleme with yubikey, Yes no gate keeping !

Hello Ougo​! 👋

I'm sorry that you're running into issues when trying to sign into 1Password using your YubiKey. I've removed the implied profanity in your post, please remember that this is a family-friendly community and I recommend that you review our Community Guidelines. You can always reach our support team by sending an email to support@1Password.com 

And your windows software are getting in a loop while trying to use my Yubikey !

Can you tell me a little more about the issue that you're running into? Are you stuck on a screen that says "Tap your security key to finish signing in to your account" when you try to sign in to the 1Password for Windows app? If you are then try the steps here: If you can’t use your security key with 1Password for Windows

If you're running into a different issue then can you post a screenshot of what you see on your screen so that I can better understand the situation?
