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.
I recently really messed up entering the password to my gmail account and had to go through the process of verifying my account and who I was. When I originally opened my gmail account was one of the things I was asked. I had no idea. Fortunately my “welcome” message to my gmail account was in my old messages in my non-gmail account and I had never deleted it.
