There's a Gmail account I've lost forever because Google wouldn't let me in even after doing 5 factor authentication (password, phone number, code from SMS, backup email, code from email).
Heh, same for me. (albeit only three factors, but more weren't configured)
It was firstname.lastname@gmail.com that I lost, as I was mostly using my original account with a pseudonym for anything private (was a teen when Gmail started, so didn't think twice about using a cringe username back then).
I had configured the first/last name Mail to forward everything to the pseudonym email and didn't access it again for something like a year... Then I had to respond to someone and... Well, Google never let me access it again.
I eventually gave up on it entirely and switched to a custom novelty domain on fastmail, much much later. (A portmanteau of my last/first name
