How to Modify Two-Factor Authentication Methods in Microsoft 365/Office 365.
In this article you will learn how you can modify the Two-Factor Authentication methods in Microsoft 365 accounts.
Two-step verification, or two-factor authentication (2FA) or multi-factor authentication (MFA), is an extra layer of security to prove who you say you are, when trying to log in to online services (banking, email , etc.). Likewise, in Microsoft 365 after entering the username and password, users are required to confirm their identity with one of the following authentication methods:
- A notification in their mobile through the Microsoft Authenticator App.
- A Call to their Phone
- A Text message (code) to their Phone
- An Verification Code in an alternate Email address.
Multifactor Authentication/Two factor Authentication (MFA/2FA), is a security default in Microsoft 365 for business, and in a previous article we mentioned the way to turn-off MFA for all users in Microsoft 365 Azure Active Directory, and how to enable MFA per user in Microsoft 365 Admin Center.
