The RuneScape Authenticator provides an extra layer of security for your RuneScape account. In addition to your username and password, you will use a code generated by an application running on your phone each time you log in.
With RuneScape Authenticator enabled, no one will be able to access your in game account unless they have your username, password and the code generated by your mobile phone.
As well as having the authenticator set on your account it is also extremely important that your registered email address is secure. We always recommend setting 2 step verification on your email address if you decide to enable the authenticator on your account.
