I have tried different types of Password Strength Meters or Password checkers, but all give me different results when I test the same Password, because each implements its own algorithm.
Is there some official standard or guideline that can follow me to build my own Password Strength Meter.
If there was no official standard, what features should a good Password Strength Meter check for?
Password strength is a measure of the effectiveness of a password against guessing or brute-force attacks. In its usual form, it estimates how many trials an attacker who does not have direct access to the password would need, on average, to guess it correctly.
Password Strength Checker JavaScript [Source Codes] First, you need to create two Files: HTML and CSS File. After creating these files just paste the following codes in your file. First, create an HTML file with the name of index. html and paste the given codes into your HTML file.
So, password meters are not a reliable guide to how likely it is that your password will be cracked but they do seem to nudge people in the direction of creating stronger passwords in general.
We found that meters with a variety of visual appearances led users to create longer passwords. However, significant increases in resistance to a password-cracking algorithm were only achieved using meters that scored passwords stringently.
As far as I know there is no standard as there are many definitions of what a good (i.e. strong) password should be.
Some things to consider:
