Passkeys. As someone who doesn't see the value of it, every hype-driven company seems to be pushing me to replace OPT 2FA with something worse right now.
Passkeys fix that.
Turns out that under certain conditions, such as severe exhaustion, that "sus filter" just... doesn't turn on quickly enough. The aim of passkeys is to ensure that it _cannot_ happen, no matter how exhausted/stressed/etc someone is. I'm not familiar enough with passkeys to pass judgement on them, but I do think there's a real problem they're trying to solve.
Something "$5 wrench"
Besides, if you ignore security alarm-bells going off when exhausted, I'm not sure what solution can 100% protect you.
