Do you know when you opened your gmail account? Many genealogists use gmail for their genealogy. Some of us use Google accounts to save and share images. Losing access to your account could create a real problem.
When I opened my gmail account was one of the things I was asked when I messed up my password and the answer to one of my security questions. I had no idea. Fortunately my “welcome” message to my account was in my old messages in my non-gmail account and I had never deleted it.
