Serious question, what's the risk of losing your Gmail account?
You don't need to login with newpipe
Newpipe is available from F-Droid and does not have a sign-in option. There's no Google account involved.
The APK from F-Droid has been pretty broken for the last month, and for some reason isn't getting updated. Anyone thinking of trying out F-Droid should just grab the latest release from the GitHub repo.
D'oh, I meant "trying out NewPipe".
Sadly their new UI is unusable on Android TV (nvidia Shield)
