For a simple password verification expression here is one for you:


^(\w|\d)([^\s]{3,13})(\w|\d)$


Validates that the first character is a letter or number ^(\w|\d)

Validates that the body has any character except white-space characters ([^\s]{3,13})

Validates the last character is a letter or number (\w|\d)$

Will be working on a more complex version later.
