What makes a strong password? This quick and dirty password strength meter is meant to help users learn how to create stronger passwords. Because it's written in Javascript the password is never sent over the network. Feel free to audit the code and recommend some better regular expressions, weightings, or bug fixes by submitting a comment.
Tips for strong passwords:
- Make your password 8 characters or more
- Use mixed case letters (upper and lower case)
- Use more than one number
- Use special characters (!,@,#,$,%,^,&,*,?,_,~)
- Use L33t
- Use a random password generator/password vault like Password Safe or pwsafe
- Use PasswordMaker
