Dont use reserved special characters at passwords

Passwords must be complex.

Complexs means uppercase + lowercase + alphanumeric characters + special characters


There are many special characters but prefer unreserved ones.

For example, if you use “!” (exclamation mark), it is reserved at many places and you can have troubles.

-       It is event designator at BASH, so you can get "-bash: !": event not found" message.

-       It is used as NOT in regular expressions

-       It means LOCAL COMMAND in FTP (eg !dir), so you cant login to FTP with password including “!”


Prefering unreserved special characters like “_” (underscore) may be better.
