Can you apply a 3-factor authentication method

Dimitrios Siskos 20 Reputation points

I have a query regarding the current authentication options available and the possibility of further enhancing account security.

Moreover, I am interested in exploring the option of implementing a 3-factor authentication method to fortify user account security even further.

I would like to know whether it is possible to introduce a third layer of authentication in addition to the standard password and authenticator app OTP, Temporary Access Pass (TAP), etc. This additional layer could involve sending a one-time verification code via SMS or a voice call to the user's registered phone number, thus requiring the user to authenticate themselves in three distinct ways.

A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation.

    That SMS option is already there and you could use FIDO keys or Certificate based Auth if you want to add additional layer of MFA, including the Auth App Passcode.

    Check this document for detailed MFA deployment options -

    Passwordless -

    Certificate based auth -

    Microsoft Auth App -

    Hope this helps.
