Not only does the credit bureau max out their password length, you have a small list of available non-alphanumeric characters you can use, and no spaces. Also you cannot used a plused email address, and it had an issue with my self hosted email alias, forcing me to use my gmail address.
Both Experian and transunion had no password length limitations, nor did they require my username be my email address.
Update: I have been unable to log into my account for the last 3 days now. Every time I try I get a page saying to call customer service. After a total of 2 hours on hold I finally found the issue, you cannot connect to Equifax using a VPN. In addition there is no option for 2FA (not even email or sms) and they will hang up on you if you push the issue of their security being lax. Their reasoning for lax security and no vpn usage is “well all of our other customers are okay with this”.
The actual length of the password isn’t the problem. If they were “doing stuff right” then it would make no difference to them whether the password was 20 characters or 200, because once it was hashed both would be stored in the same amount of space.
The fact that they’ve specified a limit is strong evidence that they’renot doing it right
Some hashing algorithms are suspectible to long password denial of service so it’s recommended to limit the length of password but certainly not to 20 characters but to a more reasonable limit, like 100 characters or so.
Fair enough, I didn’t consider compute resources
It does, I’ll give you that. However, I will hold the fact that their maximum is actually reasonable against that. The minimum of 8 is more concerning imo
