Help Help. Contacts delete themselves

[jj14x]

Glad to hear something worked, but you really should continue investigating what is causing these deletes. This (calendar entries or contacts being deleted) is definitely not normal.

Personally, I'd be worried that there is either a rogue/badly-coded third party app, or that access to the account has been compromised. Do you have two-factor authentication set up? If not, do consider it.

What is a two-factor authentication?

What is a two-factor authentication?

Google calls it two-step verification, but it basically requires a 6 digit code that changes very frequently in addition to your password to log in. That way, even if somebody knows your password, they can't get into your account without the ever changing 6 digit code (you will have a Google Authenticator app that will give you this 6 digit code when you need it, and you can create permanent "Application passwords" for trusted devices).
