DoubleSafe!

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