Websites that impose their password pattern

Some websites insist that the password must fit their pattern, such as:

* must be at least 8 digits.
* must be more than 8 digits
* must be exactly 8 digits
* must have both numeric and alphabetic characters.

The designers of these websites forget that the ordinary people, like me, have to deal with more than 10 different websites and passwords. By insisting on a password that fit their pattern, they force the user to create an unfamiliar password that they are likely to remember quickly.

Singpass insist that the password must be more than 8 digits. I keep forgetting my password. I must have asked for it to be re-set at leat 10 times.
