![]() Which is where one password manager, in fact 1Password, comes in. These would, of course, need to be random rather than your idea of random. Instead, go for five or six, or more if your memory will allow. Just three words, no matter how random, would make a spectacularly poor master password if you ask me. Rather than go over old ground involving muscle memory, encrypted USB sticks (which need yet another password) or a biometric device (JEMpass) and even dice with multiple patterns rolled randomly into a locked box (DiceKeys), let’s approach this from the three random words angle. Of course, the perennial problem of master password creation rears its very ugly head once more. What I am suggesting is that, rather than getting people to use three supposedly random words, it would be far better to advise them to use some form of secure password manager instead. This is true, and I’m not suggesting that Password, or or even is a super-duper credential to be using. Their argument generally being along the same lines as the NCSC, that adopting a three random words approach will create stronger passwords than those we often see being used and reused today. Look, I perfectly understand plenty of security professionals disagree with me here. “Phrases like young man which come up often in speech are proportionately more likely to be chosen than rare phrases like young table” the research concluded. Its evidence on multi-word passphrases was pretty damning: “By our metrics, even five-word phrases would be highly insecure against offline attacks,” the researchers found, because people naturally sway towards speech rather than randomness. There’s a really interesting piece of research from the University of Cambridge Computer Laboratory, admittedly now almost a decade old but still relevant, that explains this very well. Humans just don’t do randomness well that’s why there are computer-me-bobs for creating truly random stuff, and more on that later. Patterns in both the connections between the words used to make recall easier and patterns between the passphrases themselves to make multiple ones easier to recall. What people will do is, totally subconsciously, adopt patterns in the phrases they come up with. Most people, most of the time, will choose three words that are far from random when constructing a whole bunch of passphrases. This brings me to the second problem I have with the advice: the reality of randomness. Let’s now iterate over a loop in JavaScript, based on the password length configured, and use our randomly generated characters. Iterate Over Password Length, Adding Generated Characters Using JavaScript’s Math.floor() and Math.random() we can be sure we return unique characters each time. Repeatedly outputting randomize function using console.log() ![]() Change the number at the end, and you should see new characters appear each time it runs. ![]() To make more sense of this, you can open your browser’s console tab and paste the return line from one of these functions. This means a string character can symbolize a number added. The built-in omCharCode method can create a new string from an existing character code. Let me start by saying I know these are very confusing to understand! Each function returns a string value. I also used newer CSS variables to avoid repeating myself in a few spots concerning colors. You’ll see I’ve added a gradient for the main background. gradient : linear-gradient ( to right, var ( -teal ), var ( -blue )) īox-shadow : 0 10px 15px -3px rgb ( 0 0 0 / 0.1 ), 0 4px 6px -4px rgb ( 0 0 0 / 0.1 ) ![]() I added the following code within the head tags of the HTML page so the font renders. There’s a Generate button and a Copy button to make it easy to grab the password for quick use.įor the body of the page I’ll use a Google font called Lexend. The generator has a text input where the final password will display and a set of controls to configure the password character types, including numbers, symbols, and length. ![]()
