While a million might sound like a decent pool to choose from, its fodder for hackers. There are only 1 million possible combinations for a six-digit numerical code and a staggering 10,000 with four-digit number codes. Don't Miss: 24 iOS 11 Privacy & Security Settings You Should Check Right Nowįour- and six-digit numerical passcodes are weak.But a four- or six- digit number code isn't strong enough for the password-cracking weapons of today, so you should definitely consider making your passcode stronger. This makes sense since Apple would want the default passcode option to be these short, easy-to-remember PINs so users wouldn't forget their passcodes and get locked out of their devices. You could even have a four-digit numerical passcode if you want, which was the default option in iOS 8 and below. If you're concerned, you can take steps right now to beef up your passcode and prevent outsiders from gaining access to your device.Ĭhances are your iPhone's passcode is six numerical digits long, which is the default passcode option on new iPhone models. New tools from Grayshift and Cellebrite are popping up faster than ever to help government agencies, as well as traditional hackers, break into iPhones. ShuffledString = shuffledString.There has been significant debate over law enforcement's right to access our digital devices in recent years. 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. For someone who is looking for a simplest script.
