I wish to make my own mobile app

Hello, im not sure if this has been done, or can be done. However i wish to make my own mobile application for my website, that my users/members can login to. So essentially i would like to use the same login information that users have already provided. Can anyone help me out with this?

It’s not so clear what you’re trying to do.
But maybe this can help:
