I too am very curious about this. Even if his password was exposed and he didn’t have 2-factor auth, doesn’t Google by default ask for confirmation — e.g. texting a number or backup email associated with the account — when seeing an unrecognized device? Maybe he didn’t have any alt contact methods associated with his account?
(which might not be that unusual, he’s old enough to have opened a gmail account upon launch, before extra info hoops were put in place, and maybe he never touched his account config in the past 2 decades?
