The Pain of Passwords
"Through 20 years of effort, we've successfully trained everyone to use passwords that are hard for humans to remember, but easy for computers to guess." - XKCD
Some websites enforce rules that THEY think will be right for their users.
devising good passphrases or using the shift-to-the-right method work better for you. As a result of this, users will have to break their pattern of framing & the chances of forgetting a password are higher.
To me, a reasonable password policy is one that allows alphanumeric and special characters and is of five characters or more.
Here is a list of websites that have unusual policies -
* Doesn't matter if you took care that your password is at least 6 characters long including 1 number and 1 letter, Skype still decides if your password is complex enough.
* Airtel - Three consecutive characters or numerics(!) should not be same.
* Naukri.com - Special Characters Other Than (Hyphen Underscore Dot @) Are Not Allowed
* Prometric -
- must be between 8 and 20 characters.
- must contain at least one alphabetic character.
- must contain at least one numeric character.
- can not be your e-mail address.
- can not have any spaces.
- is case-sensitive.
