I mean physics is insane in general. XKCD had a video the other day that mentioned that if you had enough light/a strong enough laser, space itself stops being transparent because matter suddenly starts materialising out of nothing and blocks the light.
The point of 2FA isn’t that if your password is weak it saves you. The point is if your password gets leaked somehow (you accidentally enter it on a fake site, the site gets compromised, someone looks over your shoulder), they still can’t enter without the 2FA. I hate SMS 2FA (it’s not even secure) and sites that make you go through 3 steps for some reason, but the 6 digit code ones really aren’t that big of a deal, you just whip out your phone and open an app.
