Bug: Unable to add an account to 1Password on iOS when using a Security Key for 2FA

Hi there @itsbrenoakes

At the moment, our Development team are looking into why customer who have two-factor authentication turned on for their 1Password account (but only using a hardware security key) are having trouble signing in to 1Password for iOS. Sorry about the inconvenience there.

What we have found is that adding an authenticator app to your 1Password two-factor authentication options will mean you can use a one-time password to sign in to 1Password for iOS successfully without having to turn off two-factor authentication completely. The problem only appears when a hardware security key is the only two-factor authentication method.

We're tracking this issue internally, and I've added this thread to our investigation. Let me know if you have any questions or need any help. :)
