I noticed that when using psharp or fakegps for android they have a system that redirects the login from the Google system to a browser and after logging in it is redirected to the game
Someone know make that ? Or can explain me where can start?
PGSharp has a blog post with a whole analysis of their cheat. I would post the link here, but I'm not sure that's allowed. You can easily find it on google though. Credit: Romain Thomas PGSharp: Analysis of a Cheating App for PokemonGO.
