Sure, password managers are a SPoF, but in the event of a keylogger installed on the computer of someone with elevated access, you're screwed either way, password manager or not. Still, here password manager + 2FA could have helped, unless... 2FA recovery codes went through the clipboard at a time when the keylogger was watching the system clipboard... Next time I activate 2FA, I'm writing that down, in the dark, in a restroom, fold it, put it in a safe.
