Android / iOS App - Device Token Storage System with Custom Server -


so have need limit number of devices can access piece of server software wrote.

my question is, since know there's p12 file on ios nothing seemingly similar on android platforms, kind of leaning towards making token server side , storing on device.

i thinking pretty simple, user sets server key, , when user authorizes in app validates key (while sending unique id device), , server generate token send client further communications.

it's pretty google's auth protocols, in fact might see if can incorporate server perhaps... anyway, main question have is, if client limitations on server side, there way can store token on app securely other encrypting way , saving file on internal/external storage. don't want people able manually enter token somewhere , bypass system.

or maybe there's way go it. have dependency service local storage on devices, it's matter of implementation @ point , way go.
