Password

Expression |
^([a-zA-Z0-9]{6,18}?)$ |
Description |
My simple but effective password regex. The password can only contain letters and/or digits and must be at least 6 characters long and no more than 20. I know it says {6,18} but it just works out that way. The question mark was added for optimization. Also, the password can not begin or end with a space or underscore. |

This pattern does limit just to letters and digits. #12343& or $10000! would not pass
