You can enable two-step verification for all users of Administration Server if your account has the Modify object ACLs right in the General features: User permissions functional area and if you are authenticated by using two-step verification.
To enable two-step verification for all users:
In the Kaspersky Security Center console tree, open the context menu of the Administration Server folder, and then select Properties.
In the Administration Server properties window, in the Sections pane, select Advanced, and then Two-step verification.
Click the Set as required button to enable two-step verification for all users.
Enter the secret key in the authenticator app to receive one-time security code. You can specify the secret key into the authenticator app manually or scan the QR code by the authenticator app on the mobile device to receive one-time security code.
Specify the security code generated by the authenticator app, and then click the OK button to exit the two-step verification properties window.
In the Two-step verification section, click the Apply button, and then click the OK button.
Two-step verification is enabled for all users. From now on, all users of Administration Server, including the users that were added after enabling this option, have to configure two-step verification for their accounts, except for the users whose accounts are excluded from two-step verification.
