1) FTX *requires* 2FA in order to deposit. Why?
Well, it turns out that LOTs of people's usernames and passwords are basically public. If 10 years ago you signed up for some random website and it got hacked, your UN/PWD are probably for sale right now.

e) Lots of sites will say "for added security add your phone number". THEY'RE LYING! Generally doing so doesn't add any security, it subtracts security because now if someone sim-swaps you they can use that to reset your password.
This is just such a disaster. Google was still doing that constantly the last time I checked.
