Before you can sign in to Microsoft 365 with multi-factor authentication (MFA) (also known as 2-step verification), your admin needs to enable it for your organization, and then you need to set up your secondary authentication method. Once that's done, you're ready to sign in!
Sign in to Microsoft 365 with your work or school account name and password.
If you're using the text message method, for example, after you enter your password, you'll need to type in a verification code sent to your phone. Other secondary authentication methods have different ways to perform MFA, based on what you set up.
For the text message method, when you receive the the 6-digit code, type it in the box and then choose Sign in.
