Two-factor authentication with the same email address on two sites

This article explains how staff members can use the same email address for two-factor authentication across multiple school sites and the MAT MIS. It highlights the need for separate authentication profiles in some apps, like Microsoft Authenticator, and guides managing multiple accounts.

Because staff can work at more than one school, you may have:

• staff profiles set up on more than one school site
• a staff profile on the MAT MIS - when logging in via this method, Two-factor authentication will be needed for the MAT profile (if enabled), but not if logging into a school site through the MAT site

The staff member can have the same email address logged on each school site profile, and have this email be used when signing in with Two-factor authentication.

However for some authenticator apps, there may be additional steps required to enable this.

For example, Microsoft Authenticator requires a separate authentication profile for each account - one for each school. The staff member will need to manually add additional accounts to their authenticator, shown in their guidance here: Multiple entries in MS Authenticator for same username from different machines
