Due to the recent LastPass debacle, I decided to cycle my Gmail passwords. Boy that was a mistake!!
Gmail has decided that I can't log in with "just" my password. The new password is correct. It then asks me for my old password, which I put in correctly. Then it tells me I can't log in anyway. :(
Occasionally it will give me a QR code to scan. But I can't scan it on my phone, since my phone is logged out.
I can't log in to my recovery account, because (like a fool) I changed the passwords simultaneously. Now both are locked.
Somebody help! My account name is [redacted]@gmail.com (the recovery email should match my HN username). I'm locked out of a decade+ of correspondence, recovery, and historical data.
Either way, I found a solution to that on one of those Google user support forums: I had to not try and log in to the account for approximately 40 days. After that, it'd let me log in with just the password again. This is apparently because Google keeps flagging the account of getting attacked and requiring a second authentication factor for some reason and the timer for that keeps getting reset after a failed challenge for one of the account recovery factors. After something between 30 and 40 days, I could log in to the account with just the password again.
