This depends on how the organization configures things. My company used to allow TOTP so many TOTP apps could be used instead of Microsoft Authenticator but my company disabled that a while ago. Now the only authenticator app my company allows is Microsoft Authenticator using push notifications (see https://learn.microsoft.com/en-us/entra/identity/authenticat... ). Consider yourself lucky if your employer allows you to use any TOTP app you want instead of forcing you to use Microsoft Authenticator.
