Intermedia VeriKey is a two-factor authentication app that adds an additional layer of security, by requesting an additional code, when you sign in to your Intermedia service. - If you choose to use Push Notifications, the VeriKey app will display a message asking you to 'Allow' or 'Deny' access to your user account. Confirm it is you logging in by selecting 'Allow'. - If you are using one-time passcodes, the Verikey app will generate a one-time passcode that must be entered in order to access an Intermedia service.
