    Emojis are known to break systems in certain circumstances due to the way they’re interpreted in certain character sets.

    I guarantee people doing this will not only lock out their own accounts, but may even freeze some authentication servers.

      The website should feed your password straight into a well known hashing algorithm or key derivation function that has undergone a decade or more of careful scrutiny, without any other processing. The output will usually be a fixed length base64 or hex string.

      There’s a short list of about three options that are currently considered acceptable, and a few more are probably fine but are a little too easy to crack these days (e.g. anything that shares the same math as bitcoin… what if someone throws a mining datacentre at your password?)

      If the site breaks, maybe you don’t to be a customer of that service.

        It’s not the processing on the server that’s the problem. To reach the server the password needs to go through several layers of character encoding, if any of them fails the server will receive something different from what you meant. And when you try to login from another device and the layers will be different you’ll effectively be sending a different password.

      Sounds like a crappy implementation of the authentication server then, and the sysadmin deserves a paddlin’ for not stripping non-UTF characters (or making sure they work).

      My problem with using emojis as part of the password would rather be that while I might be able to enter them on my personal Android phone using the exact keyboard app I have installed right now, I might find myself struggling on a desktop computer or any other phone that doesn’t have this exact keyboard installed. After all, the graphical representation of the same emoji might look different there, and there is a chance I couldn’t even recognize it.

      So if anything, I’d say use a non-UTF keyboard like Thai or Chinese, but then a standard character in that specific type. Keyboards layout can be installed across devices and are fully standardized, even if the same character looks slightly different.

          Not from passwords, from password fields. In the same way that ", ’ and various types of brackets can’t be used since they could be used for code injections.

            That’s not how any of this works.

            First of all, stripping passwords is never okay. You can reject the password and let the user choose a new one, but never just modify it on your own.

            Then, if your system is at risk of code injection by certain characters in user input, please just shut it down and never turn it on again.

            Doing that is actually a great way to tell attackers that you’re vulnerable to that type of attack.

            Bypassing those front end restrictions is super easy, and the attackers don’t need an account or a password to attack you.

            It’s like putting a sign that says “lock fragile; don’t tug” on the door to your business.

        In my experience the only one that works with any degree of reliability is YouTube. Even the Netflix one can be fairly intermittent.

        Also a lot in the time you’ll go away and the hotel you’re in will have a smart TV and the software was last updated in 2011 so you have to sign in on the device.

      I like doing entire phrases with some rhymes thrown in. Makes it easier to remember them.

      “BonyTonyMoansHe’sOnlyGrownLonely” has a shitload of characters, and a full sentence (even a nonsensical one like that) is more memorable to me than a random handful of disparate words.

      The more ridiculous, the better. (And, naturally, don’t forget your numbers and symbols)

        You can’t compare a 46 random character password to a password composed out of words, the entropy of each is very different. Your kind of password is vulnerable to dictionary attacks which are way more common and easy than brute forcing every possibility. A 50+ characters unique random password for each service that is stored in a password manager which is encrypted with a 20+ characters random password is the most secure and future proof (for now).

          Dictionary attacks aren’t some magic bullet. There are a lot of english words and just four of them IS comparable in cracking difficult to a standard 8-char password that is as random as you can make it. There are a lot more words than there are symbols. Four words is obviously not as good as 46 totally random chars

            Dictionary attacks are definitely not a magic bullet, they require a lot of processing power, just like any other brute-force attack, but not more because of their longer length, as has been implied.

            True, there are a lot of english words, but the amount of common words is relatively small. Most people aren’t going to choose a password like “MachicolationRemonstranceCircumambulationSchadenfreude”, even if it were generated for them (which is unlikely).

            Sure, it is comparable to a standard 8 characters passward, but even that kind of password is verging on the insecure (it is the absolute minimum, which should be avoided when possible).

            There are also a lot of symbols when you count emojies and the entire Unicode standard.

      I prefer picking a sentence or so that has meaning to me, using the first letters, and then adjusting for numbers/symbols. So if I wanted to make that a pw, it’d be 1ppa505thm2m,utfl,atafn/5. -looks completely unintelligible, but as long as you can remember the sentence and have some ideas of how you would have encoded it, easy enough to remember/recreate.

          It’s as easy to remember a bunch of those as it is remembering 4 random words with no association, I think. And besides, just use that for the big, important, pws likw your pw manager.

    As a software developer who has worked with a lot of symbols and emoji… PLEASE DON’T DO THIS.

    Software doesn’t all handle these symbols the same way, and without tech knowledge (or even with, but having an understanding why) , it’s very possible to not be able to log in easily. I’m kinda drunk rn, but I’ll try to explain as simply as I can…

    For example… skintone emojis are actually two characters, a face and a skin tone modifier. I think those ones are always two characters but some of these “multi-char” characters can be normalized into a single character. But not everyone handles this the same way. For example, Safari might normalize the emoji, but Firefox might treat it as two separate characters… And this would probably make your password not match. But basically… text has lots of edge cases; I’d advise to use normal passwords please (also maybe a password manager)

      Thanks for the feedback! I’ll be sure to use non-printing characters instead of emojis for my passwords! (They can’t guess it if it’s invisible right?)

      In all seriousness, why are people so adverse to using password managers? People are plenty willing to use the browsers built-in “remind my password” instead of a proper password solution such as bitwarden…

      Emojis are standardized exactly the same way as text is, both are defined by the unicode standard. They might not be rendered uniformly, the same way that text rendering depends on the font.

      Yes there is, Unicode (Emoji's) . I would say most modern devices/systems utilize it too. The reason they may look different from device to device is because the presentation style can be modified by vendors, somewhat similar to using different fonts to make letters look styled.

        I’m convinced emojis are what has been missing from language for a long time. They are great way to portray emotions through texts, which otherwise could not be achieved.

        This way there is a difference between:

        “You are so amazing 😁👍”

        and

        "You are so amazing 🙄 "
