This article goes into detail about the importance of using good passwords and how to create them. To that end, there are many ways to create strong passwords, the primary of which is through a password generator. ![]() However, it can be difficult to think of the perfect password that will keep your account safe from any hacker. To effectively protect your accounts from being hacked, it’s important that you have a strong password with each account that you create. Hackers can get into online accounts and computers by guessing passwords, which means that your personal information would be available to them if you use a weak password. Many of these accounts contain highly sensitive information. Whether you use the internet for several hours every day or only browse it on occasion, you have likely created numerous accounts on streaming services, financial services, and online storefronts like Amazon. Randomly assigns Alpha, Numeric, Caps and Special per character then validates the password.Create Strong Passwords with a Password Generator Password=password.split('').sort(function() while (!isValidPassword(generatedPassword)) Hold = (password.length%2=0)?(hold.toUpperCase()):(hold) Ĭharacter += punctuation.charAt( entit圓 ) Var string = "abcdefghijklmnopqrstuvwxyz" //to upperĮntity1 = Math.ceil(string.length * Math.random()*Math.random()) Įntity2 = Math.ceil(numeric.length * Math.random()*Math.random()) Įntit圓 = Math.ceil(punctuation.length * Math.random()*Math.random()) Personally, I have this little bookmarklet saved in my browser bookmarks bar, for quick and reasy access whenever I need to generate a site-specific username: The idea here is to split the generated string into an array of characters, and then sort that character array with cryptographical randomness, and finally joining it back into a string. You may also optionally shuffle the final order, which is easily accomplished with this chaining "oneliner" password.split('').sort( I generally use 4, which gives me rougly 48-52 random alphanumeric characters, upper and lower cased. Length is the number of 64 bit words to join. Index % 2 ? curr.toString(36).toUpperCase() : curr.toString(36) Or we could make a fancy generic generator which uses Array.reduce to concatenate multiple random 64 bit words, alternating between uppercasing each stanza: (new BigUint64Array(length)).reduce( We could do this either by just repeating the process twice: console.log((new BigUint64Array(1)).toString(36).toUpperCase() + (new BigUint64Array(1)).toString(36)) However, to make it more secure we also want it to be longer and with mixed upper and lower cases. It should give you a truly random string roughly 10-13 characters long. Here we are generating 1 word with 64 bits of random data, and cast it to a base36 string (0-9 and a-z). The idea is the same, we're just utilizing window.crypto instead. However, for reference, I'll show a solution based on an actual CSPRNG. Since you only want passwords 8 characters long, I assume you're not interested in this. Please be aware that Math.random() was never designed or meant to be cryptographically secure. Though, you could solve this by simply concatenating two strings, and then slice it back down to 8 characters again. If you are running in an old browser, or Safari, this might mean (in worst case scenario) you get a shorter password than 8 characters. However, please be aware that different browsers and javascript implementations give different bit depth results for Math.random(). The idea is to cast a random number (in the range 0.1) to a base36 string (lowercase a-z plus 0-9), and then fetch the first 8 characters after the leading zero and decimal point.
