Does anyone knows how to change the gmail account used for Pokémon Go? I created a Pokémon account with my friends gmail account. How can I change it to my own gmail account?
There is currently (15 August 2016) no option to change the google account associated with the Pokemon GO account you are currently playing on.
You could log out and create a new account with your own google account, but you will not have access to the pokemon, items, achievements or experience you already have collected.
