This is the scenario: There are some massive process we need to run every so often, and trying to help the final user with those process, we use the "login as another user" feature as an admin user to complete those tasks.
However, with this new MFA requirement, those tasks are going to be difficult to do because there are more than 200 active users.
Any suggestions?

Does MFA affect the Log In As Another User option?
For products built on the Salesforce Platform: The option for Salesforce admins to log in as another user for troubleshooting purposes is still available when MFA is enabled for users in your org.
There's only one scenario where an admin needs to coordinate with a user to have them respond to an MFA challenge: when the user's profile requires a High Assurance session at login, but the admin is logged in with a standard security session level. To avoid this situation, admins should always log in using MFA, which automatically results in a High Assurance session.

Hence i guess you can manage via the profile settings to skip MFA for the "Logged in as" option if that helps your process
