Set up 2-Step Verification


2-Step Verification screenshot


Before enforcing 2-Step Verification, make sure all of your users and administrators are enrolled in 2-Step Verification. You can place users not yet enrolled in 2-Step Verification into exception groups so they will not be locked out of their Google accounts when you enable 2-Step Verification enforcement. 

After you've enabled 2-Step Verification enforcement, when you create new user accounts, you will need to place these new users into an exception group so they can access their account and enroll in 2-Step Verification. 

You can also specify an enrollment period during which newly created users can sign in with just their passwords. This allows them time to enroll by completing their 2-Step Verification setup.

Follow the instructions here to make 2-Step Verification mandatory:

  1. If you will require 2-Step Verification of all users in the domain or within an existing organizational unit (OU), you may skip this step. If you need to have a different 2-Step Verification setting for a select group of users within an organization, create an admin-managed group containing all such users. See Use exception groups for detailed instructions on creating custom groups.
  2. On the dashboard, click Reports, then select Security. Confirm that all users to be forced into 2-Step Verification are already enrolled in it, indicated by "Enrolled" in the 2-Step Verification Enrollment column.
  3. On the dashboard, click Security > Basic settings > Enforce 2-Step Verification on users
  4. Select the organization where you wish to make 2-Step Verification mandatory. Then select Turn on enforcement. 2-Step Verification will become mandatory within 24 to 48 hours after turning on enforcement. 
  5. From the New user enrollment period list of items, select the period of time period new users can sign in with just their passwords before enforcing 2-Step Verification.
  6. To have a suborganization inherit the 2-Step Verification setting from its parent organization, click the Use inherited button that appears near the right margin when you hover over the Authentication pane.
  7. If you would like to exempt a group of users, select the group name (created in step 1) on the right-hand side keeping the organization selected on the left-hand side of the page and select Turn off enforcement. This will apply 2-Step Verification to all users in the selected organization except the users in the exception group.
  8. Save your changes.

    All users of the selected organization are now required to enter a secondary code from their mobile device.

Enforcing 2-Step Verification ​using security keys

As an administrator, you can choose to allow only security keys as the only 2-Step Verification factor for enhanced security.

    To see Security on the dashboard, you might have to click More controls at the bottom.

  2. Click Advanced security settings.
    In the Authentication section, under Select allowed 2-Step Verification methods, two new settings appear:
  3. Choose which second factors are enabled for the domain:
    All options
    Security key only

    Note: The Security Key Enforcement feature is available only with G Suite Enterprise .
