Stuck at changing steam password-What are the steam password requirement

[Deus XI]

Im stuck at trying to change and keep my current 63 character password policy length for my steam account, but the website keeps saying vaguely "invalid password" everytime and theres no hints at all of what the problem is

I have tested a varity of password lengths with 20, 40, up to 63 characters with numbers, but without any symbols or other special characters.

What are the steam requirements in terms shorest vs maximim length passwords. Can all symbols and special characters be used?

Use at least 6 characters
Use a combination of uppercase and lowercase letters.
Include at least one number within the password
Do not use a name, a word that could be found in the dictionary, or a series of letters as it appears on the keyboard ("qwerty" and "12345" are not secure passwords)

Also, 63 is kinda overkill.
