The Default Authentication Profile allows you to use 3 Two-Factor methods when logging in. Which one is NOT an option?

The Default Authentication Profile for two-factor authentication typically includes methods that enhance security by requiring users to verify their identity through an additional means beyond their usual password. Common methods include the use of authenticator apps, SMS, and sometimes email confirmation.

In this context, the use of phone calls as a method for two-factor authentication is less common and not typically included in the standard options for a Default Authentication Profile. While phone calls can be an effective method of receiving verification codes, modern practices have shifted towards more direct and quicker options, such as SMS messages or authenticator apps, which can provide codes instantly and are accessible on mobile devices.

Auth apps are popular for their robustness against interception attacks, SMS is widely used due to its simplicity, and email confirmation serves as a viable option for many users who may not have access to mobile verification methods. However, the reliance on phone calls, which can involve additional steps and potential delays due to call connectivity issues, has led to its exclusion from the standard authentication methods in this case.
