Help Google account security measures

[zleoyodo]

During a recent breakup, my newly purchased phone mysteriously disappeared. I need to log into a (joint) Google account my (ex)partner and I created last year. I'll be using my old phone and prefer he not know. What are all the ways I can cover my tracks?
i.e. Delete my activity on Google Dashboard's Web & App activity. Remove Access to/from the device I use. Turn off my Location and/or delete it in Timeline. Check Gmail for any "Suspicious Activity" email alert(s). What else??
Thanks everyone!

After you do unlink your Google account from that phone don't forget to immediately change your account password so any apps on that phone tied to Google services that are set to autologin won't be able to do so. And keep in mind you'll then need to re-authenticate yourself on your old phone.

Well if you make a factory reset and setup your old phone from scratch using another Email account you should be OK.

Well to completely secure your google account , you must change your password asap (it will log off your account from every device ), Turn the second verification on and make up backup codes , these 3 steps will completely secure your account no matter where it was used .
