Password Strength Meter (a jquery plugin)

Filed under: WEB-APP — phiras @ 9:28 pm

@Update : Password Strength Meter V2 , new UI improvements.

Password Strength Meter is a jQuery plug-in provide you smart algorithm to detect a password strength.

The Password strength procedure is working as the follow:
We have many cases to care about to know a password strength , so we will present a global variable score , and each case will add some points to score.
At the end of the algorithm we will decide the password strength according to the score value.
The cases we have are :

  • If the password matches the username then BadPassword
  • If the password is less than 4 characters then TooShortPassword
  • Score += password length * 4
  • Score -= repeated characters in the password ( 1 char repetition )
  • Score -= repeated characters in the password ( 2 char repetition )
  • Score -= repeated characters in the password ( 3 char repetition )
  • Score -= repeated characters in the password ( 4 char repetition )
  • If the password has 3 numbers then score += 5
  • If the password has 2 special characters then score += 5
  • If the password has upper and lower character then score += 10
  • If the password has numbers and characters then score += 15
  • If the password has numbers and special characters then score += 15
  • If the password has special characters and characters then score += 15
  • If the password is only characters then score -= 10
  • If the password is only numbers then score -= 10
  • If score > 100 then score = 100

Now according to score we are going to decide the password strength

  • If 0 < score < 34 then BadPassword
  • If 34 < score < 68 then GoodPassword
  • If 68 < score < 100 then StrongPassword

  1. in the code, it has 1000 instead of 100.

  4. Wow, nice plugin. One suggestion. You might want to make a demo with a graphic visualization of the strength. Microsoft and Google both do this. Like red 50px bar for weak, yellow 100px for medium, 150px green for strong. I think this is doable right out of the box, but it makes for a compelling demo.

    Again, awesome work!

  8. is there any way to distinguish between random letters and words, or does the distinction make no difference as far as password strength?

    IOW, is HbeqqpTvnmlzdn any better than StrongPassword as a password?

    Comment by jd2718 — June 7, 07 @ 2:17 pm

  9. “HbeqqpTvnmlzdn” is WAY better than “StrongPassword”, as the first one would require an exhaustive brute-force attack, while the latter one could be broken with a simple dictionary attack. Ignoring the case (to simplify the calculation), the first would need an average of 3*(10^19) operations, while the latter would be broken for sure after 1.5*(10^13) operations using an extremely large dictionary and 100 billion attempts using a small dictionary. That means, the first one would need AT LEAST about 2 billion times the time to break compared to the first one. As dictionary attacks are the only thing anyone might even consider trying against a web application, the first password would be unbreakable, while the second one would give the attacker a slight chance. However, if the attacker managed to test 10 passwords per second using a small dictioary of 10000 words, the probability that he manages to beak the password within a week is 6% – and the wordpress admin team should notice someone hammering their server with 10 wrong auth requests per second within less than a week.

    Additionally, the “password strength meter” considers “0123456789” to be a good password. In reality, a dictionary attack would break it within quite a short time (I think about 20000 attempts at max.)

    If anyone wants to hack some blogs, he is going to do a simple dictionary attack, without going for passwords consisting of two words, so nearly ANY password not in a password cracking dictionary (qwertz, 123456, asdf and similar things ARE in such dictionaries) will protect you. If anyone wants to hack exactly YOUR block, he WILL infect your pc with a trojan and steal the password or sniff it from a network you use, and then even a password like f”gh&&sah/svSD13″bjh+§#gHW23= is not going to help you.

  11. hmm , in fact this is a simple solution (My work) , If we want to handle more complicated cases we need to do it on the server-side because we are going to use a dictionary and another detection approaches.
    We can’t do a lot of work to detect the password strength on the client browser (fully client script) , and I’m working to improve it as possible

  18. One suggestion:

    If the password *contains* the username (it’s no important the position), it’s going to be a bad password.
    Example:
    for username = paquito
    bad passwords = paquito1 / 1paquito / 1paquito1 / paquitopaquito

  23. I’m trying to use your password strength meter code but I don’t need the HTML file to be named “Index.html”. When I changed it’s name it no longer worked. I edited the 2 js programs and cannot find where the name is referenced. How can I still make this work? Thank you.

  24. Actually I just changed the name back to Index.html and ftp’d it over and brought it up on the browser and it still doesn’t work. The 2 js files are on the web server too in the same root folder. What am I doing wrong?

  27. It could be useful to don’t let users use bad passwords in registrations, not only advise them.

    Is it possible?

    Comment by Alessandro Ronchi — December 23, 07 @ 1:33 pm

  28. Yes it’s possible, you should use the algorithm in a different logic.

    Comment by phiras — December 31, 07 @ 1:06 am

  29. There are comments

    // checkRepetition(1,’aaaaaaabcbc’) = ‘abcbc’
    // checkRepetition(2,’aaaaaaabcbc’) = ‘aabc’
    // checkRepetition(2,’aaaaaaabcdbcd’) = ‘aabcd’

    in passwordStrengthMeter.js.

    But after execution checkRepetition return
    abcbc
    aaabc
    aaabcdbcd

    Comment by test — March 18, 08 @ 10:50 am

  38. 1234567891011121314 is a 19 character consist of digits only (9 options for each character), not following a clear pattern , this means : the probabilty to get this password is : 1/9^19 (1/1350851717672992089).

    I don’t think there is any algorithm could break it in minutes ;)

    Comment by phiras — March 18, 08 @ 12:18 pm

    • [First question]
      —————–
      With “1/9^19 (1/1350851717672992089)” you mean
      (1/9)^19*(1/1350851717672992089)
      or
      1/(9^19)*(1/1350851717672992089)
      or
      1/(9^19)=(1/1350851717672992089)?
      **********************************************************************
      [Second question]
      —————–
      How to calculate how many guesses have to do a bruteforce program for “1234567891011121314” password? This expression is correct:
      [1*(10^18)]+[2*(10^17)]…[3*(10^2)]+[1*(10^1)]+[4*(10^0)]?

  40. I moved your algorithm over to Python for a project I’m doing, and I noticed that the password “abc123″ got through as “good”, but was actually an early one that was cracked using John the Ripper. I don’t know if there’s any way to check for patterns (alphabetic, numeric, keyboard), but it does make the password a lot weaker when a pattern is present.

    Overall, I’d say your algorithm looks great. Thanks for putting it here.

    Comment by Brad Landis — April 1, 08 @ 10:27 pm

  41. I came up with a partial solution to finding patterns.

    I subtracted 3 points for every character that is one character away from the previous in the password (using the ord function in Python).

    Keyboard patterns is kind of hard, but I figure “qwer” (followed by “ty” most of the time) and “asdf” are more common than anything else as a keyboard pattern, so I simply searched for those two strings, and subtracted 10 if they were found.

  44. Hi, I am looking at your script and looks great, just what I need at the moment. Only one thing, when I type only numbers or letters the score should be negative.

    When typing: 1010101010101010101 It now says your password is strong but in my opinion this should not be possible.

    Is there a way how I can’t make it possible to type only numers or letters?

  61. In the script password1 counts as a good password, which obviously it isn’t. A simple preg_match could check for common passwords:

    $badwords = array(‘password’, ‘12345’, ‘123456789’);
    if(preg_match(“/\b”.$password.”\b/i”, $badwords)) return $strength;

    If anyone has a list of common passwords we could easily adapt it.

    * Must be at least 8 characters
    * Must contain at least one one lower case letter
    * Must contain at least one upper case letter
    * Must contain one numerical digit
    * Must contain one special character e.g. @#_$%^&+=

    How do I adjust my score to reflect that its a strong password once this is met?

    Thanks for any assistance.

    Comment by siddharth — May 6, 10 @ 2:41 pm

  79. Chuck,

    I would say 8 chars is a rather low score, slow increase for score after max char count
    Upper case and lower case should be joined in score (low score) slow increase in score again
    One numeric digit is high score, two is higher fast rising
    One special char is high score, two is higher fast rising
    alphanumeric combinations that do not fit an dictionary or pattern (1 after or before) are wildcards and can tip a passwords security depending on what is put.

    That’s the point system I would use

    Comment by sammaye — May 17, 10 @ 5:12 pm

  80. Hi Sammaye,
    I appreciate your reply, but I guess I am kinda lost on your response on how to score it according to the scripts, scoring parameter settings.
    I do have to have it a least 8 characters but maximum of 16 with the same parameters as originally stated.
    Can you give me an example on how you would modify the scoring in the script file?

    -Chuck

    Comment by Chuck — May 17, 10 @ 6:00 pm

  81. Hi Chuck,

    I’m not sure if it’s the code reply or the theory reply you want but since I haven’t looked at this code properly yet (haven’t had a chance) I’ll give the theory based reply:

    – If password matches username bad password score = 0
    – If password is less than 3 characters score = 0
    – If password is 3 chars long add 10 points. Do not add score until password length is 8. This will make the score = 10 until password reaches minimum requirements. After 8 characters add 2 points for each letter.
    – Now to deal with lower case and upper we will say that 1 and only 1 lower case is worth 5 points. Multiple lower case do not get points.
    – 1 Upper case letter gets 5 points.
    – 3 upper case letters spread out (1 or more lower case letters or digits in between) gets 15 points
    – for both lower and uppper case add 15 points
    – 1 number in password gets 5 points
    – 2 numbers 2 upper case spread out (not bunched together i.e. as an example of what wouldnt pass out score frED123) gets 15 points
    – if password has 1 special character score is 15 points
    – if password has numbers, letters and special characters thats 15 points
    – if password is all letters -60 points
    – if password is all numbers -60 points
    – if password is common -80 points

    I know that don’t add up to 100 but that should give you an idea of what to do. There may be one or two clauses I ain’t thought of but overall thats a good start.

    Comment by sammaye — May 18, 10 @ 8:42 pm

  82. Hi Sammaye
    I appreciate your scoring methodology. This will help as I try to modify the file. I was actually looking for a code reply of this module. But I do see where you are going with it. Ill look into the file and give it a go.

    Thanks again for your response. Much appreciated.
