Best 8 digit password8/17/2023 With a modern computer, it’s quick.īrute Force Attack: As the name suggests, brute force is used to determine the password by methodical, logical means, but in relentless volume and at speed. A dictionary attack smashes “The Dictionary” – and variants – at the password entry point. Hacker methods employed, in general terms from a compute perspective:ĭictionary Attack: There are according to the Oxford Dictionary, some 600,000+ words in the English dictionary, past & present. Putting aside the casual glance by someone looking over your shoulder or finding the password scribbled on a Post-it note under your keyboard, this leaves the prospect of a computer focused on deciphering it.Ĭomputers capability is sheer speed and being able to reference different datasets to “smash” a bunch of combinations quickly, mindlessly and efficiently. But how do you remember it?Īt the heart of a good password is two things: Increasing the length to at 16 characters is ideal, which would take a much more acceptable “1 trillion years” for a computer to crack. Recently I was asked if the “Recommended by the Bank” 8 character uppercase, lowercase, number and special character password is still appropriate in 2020.įor example the password: d)4M*L&K meets all the requirements of the typical “good” 8 character password, whilst also not being easy to remember upon cursory glance.Ĭhecking the password strength tool here at “ it shows its broken by a standard computer in 8 hours. ShuffledString = shuffledString.Originally appeared on Var randPassword = new Array(pwdLen).fill(0).map(x => (function(chars) ).join('') Three-liner: var pwdChars = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz" assumes that crypto.getRandomValues and Array.fill() are both available.it uses only native Javascript- no installation or other libs required.it's more concise than other answers (for general solution, 3 lines max can be one-liner) (OK well, sort of depending on how much you squint your eyes looking at a "line"). it's more secure than accepted/highest-voted answer, and also more versatile, because first, it supports any case-sensitive character (including any of the ~150k (at the time of this writing) unicode chars, rather than just one of 36 case-insensitive alphanumeric ones), and second, it uses a secure random generator that is applied uniformly.Anyway, fwiw this update addresses both, which I don't believe any other answer does. Many other answers berate the use of Math.random() and then go on to use a better random number generator that is non-uniformly applied, with an end result that (just like using Math.random!) is not cryptographically secure. Many answers (including the original of this one) don't actually answer the letter- and number-count requirements of the OP.īelow are two solutions: general (no min letters/numbers), and with rules as specified in the OP. map((x) => wishlist)īookmarklet javascript:prompt("Random Uint32Array(o))).map(o=>n).join(""))())Īom(crypto.randomFillSync(new Uint32Array(length)))Ĭhars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890-" var generatePassword = (Īom(crypto.getRandomValues(new Uint32Array(length))) No while (true), no if/else, no declaration.īase on mwag's answer, but this one uses crypto.getRandomValues, a stronger random than Math.random.
