Just the other day I received a notification on my phone that there was an error signing in my account due to some settings were changed. I relogged my account and it went fine until after a few hours later the same notification popped up again. Curious as to what setting might have changed I checked my device ID through an app and it was different from the one when I first created my google account. What could have possible caused the change? Is there reason to suspect that my google account might have been compromised?
