Well, I've actually faced an opposite situation. I have two Gmail accounts, main one gathers mail from the secondary, and I'm pretty sure that main address is set up as "recovery e-mail" in the secondary account. I've registered them more than 10 years ago, and since I have no need to login into secondary account - I forgot my password. But recently I've received e-mail from Gmail saying "we've prevented login into your account from unusual place" which usually means - somebody has your password.

And now I have no way to change a password for my secondary account meaning bad guys still have a valid password. And since some services don't allow you to change e-mail you've used during registration (usually when your e-mail is your login) - I'm basically hostage to Google's login security system and have to rely on it preventing bad guys from logging in into my account while I can not do so myself.
