Setting a max password length is sometimes done to prevent ddos attacks. Without it, attackers could just spam 1MB passwords constantly and force the login server to just spend all its cpu time hashing garbage.
That being said, a password limit of under 20 characters probably just means they are just storing passwords in plaintext.




Late onset type 1 diabetes for me. The big symptoms for me were suddenly having to use the bathroom all the time and everything being blurry. I got those symptoms all of a sudden after being down with covid for a week. Diagnosed about a month later with an a1c of 10.
Metformin and a low-ish carb diet kept it in check for a bit before my doctor figured out it was type 1 and put me on insulin.
