Can I sign into my Pokemon Go account on a different phone with a different Google account?

Solution 1:

You can also do this through the PHONE SETTINGS :

AFTER CONNECTED TO A FACEBOOK ACCOUNT (nowadays it need to match the email /gmail your PoGo Acc is connected to)

  Go to  : 
 -> SETTINGS (your phone's "settings")
 -> GOOGLE SETTINGS
 -> (SOME phones have something between these two, i can only say it's called "Kontotjenester" in Norwegian) 
 -> CONNECTED APPS
 -> CHOOSE THE POKÉMON GO APP  (and confirm you want to disconnect it from Google)

--->>   NOW PROCEED THE PREVIOUS MENTIONED STEPS TO CONNECT IT TO A NEW GMAIL ACCOUNT:)

I do recommend you have it connected to some gmail even though you have it connected to Facebook as well - it's just safer. Good luck ♡
