The nice thing about Google is that your account acts like an umbrella account. You don’t have to hunt down every google service. You can de-google straight from them. The messiness comes from using/not using google to sign in to other services, this takes some time to work through if your email login across the board is google. There’s a 3rd party sign in page on google security and privacy settings that shows some of the services with access to your account.
Once you’re fully removed, services like Cloaked or MySudo will help keep accounts unique and identifiable should issues arise. You can also change all the accounts you can think of now and as the others start to pop up over time you can update accounts as you go.
I guess for some it’s easy. Maybe not everyone who signs in multiple ways. But it’s a very important step toward protecting your online privacy and presence. Most don’t start or delay perpetually because the task seems too demanding or the perceived risk doesn’t outweigh the reward.
How many times has your personal info been leaked in the last 5 years?
How many of those had a Gmail account in the leaked data?
If your number is more than 0, you should de-google now.
