Enforcing SSO or MFA authentication requirements for access to the Signature 365 web portal - Signature 365

It is possible to configure Signature 365 to enforce SSO or MFA authentication requirements to access the web portal. Both SSO and MFA authentication can be enabled for an account, but enforcement can only be applied for one authentication method at a time. To enable this, follow the instructions below.

Log on to the Signature 365 portal, and select Teammates from the menu item.

Select the Authentication Policy button from the Teammates screen

Teammates page with the Authentication Policy button highlighted beside the Invite button.

By default, enforcement is disabled for a Signature 365 tenant.

Select the enforcement type that you require. This will detail the number of users that do not currently have the authentication method enabled. Selecting the notify option will email any users to prompt enrolment.

You must set up the selected method for your own account before enabling enforcement. Select Set up now in the warning to do this.

Authentication Policy window with Enforce Microsoft 365 Sign-In selected, a warning that you must set up Microsoft 365 Sign-In for your own account, and the notify users checkbox highlighted.

The same option is available for multi-factor authentication:

Authentication Policy window with Enforce Multi-Factor Authentication selected and the checkbox to notify 2 users by email highlighted and ticked.

The current sign-in method for a user is listed along with their details on the Teammates screen.

Select Continue, then click the Enable policy button to turn on enforcement.
