Was Yubikey support removed ?

Understood, thank you for the update @shampoo!

Thanks. Got it. I had to log out and log back in again to have the option.

@shampoo:

Support for Yubikeys was not removed:

https://support.1password.com/security-key/

The only option appears to be an authenticator app:

As rootzero wrote, after you add an authenticator app, you will also be able to add a security key to your account :+1:

@shampoo 1Password doesn't support hardware security keys on all platforms. So you need to add an authenticator app before you'll get the option to add a hardware security key.
