Sure. All the officeatwork Apps & Add-ins require Microsoft accounts to sign-in. If you have activated MFA (Multi-Factor Authentication) for our Microsoft Work or School account in Microsoft 365, then that will automatically also apply to the officeatwork Apps & Add-Ins. You as an Admin do not have to configure any dedicated settings for the officeatwork Add-ins as they automatically 'inherit' your sign-in policy you defined for your organization.
