At Hostmonster, they've updated the security and I'm now asked to create a new password. I already used something quite safe for my own use: not a dictionary word, contains numbers and makes absolutely no sense.
However this is not enough, since Hostmonster went batshit insane with security and requires a password that contains an uppercase letter, a symbol and a number that must contain at least 8 characters. For Pete's sake, I'm a grown adult now, I can choose my passwords myself, and I'm pretty certain that no one will even try to log in on my account anyway.
Thanks for wasting my time.
