Hello. My name is***** to JustAnswer. I'm reviewing your question now, and will post back with your reply momentarily.
When is the last time you signed in from Chrome, Firefox, IE etc. When is the last time you could sign in to that account and what were
you using when you signed in at anytime recently if you could sign in? Phone, pc i just asked about, iPad etc?
Please list all devices you were able to sign into that gmail account on recently without issue.
