Most websites will send a password reset via email, so set the password for that email account to something completely different, just in case you ever forget the main password!.Using UPPER or lower case will produce different passwords, when using this for the first time it’s a good idea to use the 'Show Password' tickbox to check for any typos.Not all websites will accept 20 character passwords yet, though support is improving all the time, see also the 15 character version.For any website that's not on the list, just type the name into the 'Custom' box (the last one in the list) and press Generate.Using a different PC? you can re-generate the same set of passwords at any time by returning to this page and entering the same main password.

Copy and paste the new password(s) into the website and set your web browser to remember them.Īll the websites get different passwords, but you only have to remember one!īecause the generator uses a one-way SHA-256 hash, knowing one password does not allow working backwards to discover the main password or any of the others. So, the idea is that you memorise just one, reasonably long, secure main password and use that to generate a set of non-dictionary passwords.
It looks great on the iPhone and is at least fully functional (if not always so pretty) on all other HTML5 platforms.Using the same password for multiple email, shopping and social networking websites is risky, it means that a security breach at one website will compromise all your accounts, possibly even leading to identity theft. The symbols were selected to be easy to get to on an iPhone, that is, they reside only on the first page of symbols without needing to shift first to symbol mode, then shift to the alternate symbol mode. You can tell it the number of words you want and whether you’d like a separating symbol between them, which increases the difficulty in someone’s attempt to brute-force your password. This generator is a little more flexible than the Python script I used. Also, because this is entirely offline, you can add it to your iPhone’s or iPod Touch’s home screen and it will act exactly like a native application, with no network access required. Nefarious people watching the bits and bytes flowing over the network can only see that you downloaded a list of words, but not what combinations of words the generator has come up with. You can verify this by viewing the page’s source. All of the logic to generate passwords runs only in your browser and never touches a server once the page has loaded. This “application” lives entirely in JavaScript and contains all the right mojo to run 100% offline. My iPhone is ubiquitous, so I thought I’d write an app, but realized that more people would find an HTML5 “app” useful than a native iPhone app. It would be nice to have something portable. My main problem with this script is that when I’m first setting up a new machine, I don’t always have the script available. I usually have to run it a dozen times until I get two words that “work” for me and my brain. You end up with things like “tine^miner”. It consults your computer’s dictionary file, grabs two random words, then joins them together with a letter or symbol in the middle. I have no idea where I originally found this script, but I always try to have it around. The password-choosing technique that I have used for about as long as I can remember is based around a Python script called password.py. It’s only marginally more secure than picking a dictionary word.
Usually people pick a word and use “leet speek” to convert letters to numbers and think that’s secure. A while back, the web comic XKCD had a great observation on picking passwords and password strength.
