It depends what you mean by character and special character. The following javascript regular expression will validate a password which contains: 1. At least one alphabetic character a-z or A-Z 2. At least one digit 0-9 3. At least one apostrophe underscore or hyphen var expr = /^(?=.*[a-zA-Z])(?=.*\d)(?=.*['_-]).*$/
