I had this happen as well about 8 years ago. My Gmail account one day just said it couldn't log me in, even though my password was correct, and I was logging in from the same home address and browser as always. It said I needed to complete the security question to access my account. I didn't know the answer because I just set random letters and numbers for the security answer when configuring the account recovery, because I was confident in my password and backup system. Since I couldn't answer that question, and because Google has no support, I could never access that account again while knowing the password.

Fortunately this was a secondary email address, and my primary email was on my own domain.
