How to get access token vk without binding to ip?

Good time of day. Started to learn api Vkontakte, parallel sawing simple Messager without using vk sdk. Use a simple client authorization. Faced with this problem: when changing ip addresses access_token becomes invalid, and you have to re-enter login and password. How can this be fixed? Thanks in advance

Need to do authorization with rights offline, then the access_token will not be tied to ip and will be indefinite.

Of course this access_token is not eternal. It will stop working if the user will change the password or ban the app permission in settings.
