I would like to add non-SMS, non-Apple 2-factor authentication to my Apple ID account.
- Google Authenticator
- Microsoft Authenticator
- 1Password "One-Time Password"
I do not see any such option. Is this type of authentication available for Apple ID accounts?
I am also interested in Yubikey and other similar non-SMS 2-factor or 2-step solutions.
Note: I am able to add the Apple proprietary code-generator system integrated within iOS and macOS as an alternative to SMS-based 2-factor. This question is asking instead for a 3rd-party-compatible 2-factor or 2nd-step mechanism that can be used as an alternative to the SMS-based auth that Apple does currently support.
