Javascript Random Password Generator

The above random password generator will generate a random string of any combination of letters (upper and lower case), numbers and symbols. The process of acquiring such a word is done completely on the local computer without passing through the internet.

Feel free to use http://generatemypassword.com any time you need a new password. Our easy to follow Password Practice will help you memorize the password without having to write it down!

Password Security

General guidelines to create secure passwords:

• Include a combination of symbols, numbers, and lower and upper case letters.
• Do not contain a dictionary word (in any language!).
• Do not represent a bank account, pet name, postal code, building address, or any other personal information.

You can never be too safe. You should also have different passwords for all your accounts and try changing the most vital ones every 90 days or more often!

How To Remember Passwords

There are numerous ways to remember a password including trying to come up with a phrase that will have its words beginning with the letters of the password. In our case we also have the numbers and symbols to worry about so it may not be feasible.

It has been long proven that the best learning exercise is a simple repetition. We have come up with a script that would allow you do that right while you looking at the password.

Random Number Generator

The random number generator used above is considered to be a pseudo-random number generator. That is, it is not a purely random process but rather one that has been obtained following a set combination of instructions to make it look as if it were random. Usually a starting point, called a seed, is picked and then transformed into a random-looking data.

Ever since invention of computer systems it became required to produce random numbers for computer application (i.e. gambling sites, security passwords, etc.). There have been invented various truely random number generators for these reasons. We will not go into detail about such processes as you can easily read them on random.org - introduction to randomness and random numbers.

For the purpose of this site though, pseudo-random process of creating passwords is good enough.

Javascript Source Code

The following is the current javascript source code in use:

// create a list of all available characters // uppercase uc = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; // lowercase lc = "abcdefghijklmnopqrstuvwxyz"; // numbers num = "0123456789"; // symbols acceptable in most passwords sym = "!#%&'()*+,-./~:;<=>?@[\]^_`{|}"; // generates a random character function get_random_char() { possible_characters = ""; // check to see which boxes have been selected if (document.getElementById("ucletters").checked == true) possible_characters += uc; if (document.getElementById("lcletters").checked == true) possible_characters += lc; if (document.getElementById("numbers").checked == true) possible_characters += num; if (document.getElementById("symbols").checked == true) possible_characters += sym; // return new random character return possible_characters.charAt( Math.floor(Math.random()*possible_characters.length) ); } // generates a password of certain length function generate_password() { pass = ""; // get new characters for the length specified // *** make sure that symbols are not used as the initial character for (i=0;i<=document.getElementById("wordlength").selectedIndex;i++) { ch = get_random_char(); if (i==0 && (sym.indexOf(ch)!=-1 || num.indexOf(ch)!=-1)) i--; else pass += ch; } // display the newly created password document.getElementById("password").value=pass; } function practice_password() { pass = document.getElementById("password").value; for (i=0;i<=pass.length;i++) { user_entry = prompt("With each correct password entry, we will remove one letter. "+(pass.length-i+1)+" more times!\nPassword: "+((i==pass.length) ? "[enter entire password now]" : pass.substring(i)),""); if (user_entry != null && user_entry != pass) { alert("Incorrect, try again!"); i--; } else if (user_entry == null) break; } alert("Hopefully you now remember the password, try again if you still need to practice!"); }

You may simply copy the code and use it as you like, make sure to create valid form fields for the code to work.
