Let’s have a look at this article on how to enable or disable multi factor authentication in Microsoft 365. This article is for Microsoft Office 365 customers who want to make their email accounts secure with MFA. Multi-factor authentication keeps people from accessing your Microsoft 365 account without your permission. MFA requires that you enter a verification method, such as a code sent to your phone via text message, each time you log in to your account. If your password is ever compromised, attackers can’t copy this way of verification, so they can’t get into your account.
Note: You need admin permission to change MFA settings.
