I mean banks are known for horrible security practices all around so that makes perfect sense.
Are they?
Darren Kitchen from Hak5 has an amusing story about a bank teller who assured him email was entirely fine to send sPII through. "No sir, you just need to send it to us, and once we have your information then it'll be secure." No encryption. So, yes.
Also look into the Equifax security breach. Un-patched software for months.
It makes almost no sense to have a password length limit. 1_000_000, that's One Million, characters is equal to 1MiB. That's twice the length of the Lord of the Rings Trilogy and much less than most modern webpages. After hashing, which is how passwords should be stored, text length is irrelevant. All hashed inputs come out the exact same length. 65 characters for SHA256.
Very much known for their horrible security practices, yes. Absolutely.
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.
In Brazil, the govt owned lottery site, created around 2015, only accepts passwords with 6 numeric digits. Your password has to be a number between 000000 and 999999. Only somewhat recently (6 months ago or so) they've added a 2FA through an email link.
Oh, said lottery is run by the biggest govt owned bank. Chances of people reusing their bank password there are very fucking high.
