Enforce stronger passwords for users by checking for uppercase/lowercase letters, numbers, and special characters. This is ideal for preventing users from entering their name or email in the password.
The following passwords are considered Strong by your algorithm: Now these do not look like strong ones to me, let's have a look at how many possible combinations such a password has.
The total character set for these passwords is 26 (lower) 26 (upper) 10 (digits) 14 (special) = 76.
validate Empty ( ) The function below checks if a required field has been left empty.
If the required field is blank, we return the error string to the main function.
Also there are many factors that can kill password security completely, for example the user themselves or social engineering.
Your scale goes from 0 (Very Weak) to 5 (Strongest).
The following regular expressions check many individual conditions, and can be mixed and matched as necessary to meet your business requirements.
At the end of this section, we’ve included several Java Script code examples that show how you can tie these regular expressions together as part of a password security validation routine.
The Because of how this password ranking algorithm is designed, it can serve two purposes equally well.
