Having troubles logging back in to my main account

I logged out of my main account and made an alt to test my server permissions, and as for an amazon fire 7 user, i cannot log back in because i have to verify, and i didn't download discord from the app store, i got it from an APK (Look it up if you don't know) and it says Discord won't run without google play services, and the browser option doesn't help, So i really need to log back in to my main account as i have a server with 30 members I have to moderate, My username on my main is Mr. BrokenDreams#2009
