> They often have to guess several times to remember their password.
I think pointless password rules are at the heart of this problem for many non-technical people who probably haven't been operating with a password storage solution and might not be used to that system or trust it.
Every platform has their own special requirements for passwords: some require a mix of capital and uppercase letters, some require numbers, some require a special symbol, some require a special symbol but no not that one, some restrict you from entering 3 of the same character in a row, some passwords have a short max character limit, some prevent certain characters like spaces, some require you to change it every so often, etc. Eventually, the password is forgotten or confused with another because of these pointless password rules.
I called them pointless password rules because they reduce the possible number of combinations required for an attacker to guess the password because any guessing program knows what can't possibly be valid combinations.
