The worst is when some forms set rules but prevent the user from pasting a string into the duplicate field for verification. If this is meant to prevent user error in case of a typo in the first field, then it also thwarts many of us using password managers. Somehow my browser can auto-generate and enter a password, but I can’t. That’s a work-around, but it’s irksome anyway.
On another note, a more constructive metric for password security on a basic website account would be to set a complexity standard that allows multiple ways to get there. A haiku of approximately 60 plain characters, for example, should be as secure as a 30 character alphanumeric string, at least when it comes to brute forcing. It seems to me like plenty of weak passwords could be created to eke out the minimum requirements for a lot of sites, so this standard lends a false sense of security, especially when any password is recycled.
- dan-robertson 5y agoEnglish has about 1 bit per character of entropy so if you type a normal expression it is going to give you ~60 bits of entropy. Random words will give you something like 2-3 bits per character so ~120-180 bits for a 60 character string. Random alphanumeric strings have about 5.95 bits of entropy so you get 178 bits from 30 of them. So your comparison is somewhat right but only with an annoying definition of haiku and dictionary of words. However, a less good scheme should still be fine
