Welcome to password creation hell
- Zhenya 9y agoThis seems to significantly narrow down the possibilities of passwords - why would they do this?
- incomplete 9y agosomeone had a "really good idea", apparently. :\
- justin_oaks 9y agoOne word: incompetence
- stretchwithme 9y agoDoh! You guessed my password.

- daurnimator 9y agoQuoting password requirements here for discussion: > Your new password must contain 9 numbers, and include at least 4 different numbers but cannot include the same number more than three times. > To create a new password you will need to confirm some basic personal details (name, date of birth and National Insurance number). > These must match the details recorded on your Devon Home Choice application.
- danso 9y agoI wish I were clever enough to do a back-of-the-napkin calculation quickly; maybe someone else can do it. What are the number of possibilities given the constraints above, and some reasonable assumptions of human behavior: - At least 2 to 4 numbers will be reference to a specific year, such as the user's birth year or the current year, e.g. 17, 1965, 2017. - As many as 3 to 4 numbers will be a predictable pattern, such as an incremented sequence or repetition of numbers not likely to be a birth year or of `2017`, e.g. `1234`, `987`, `1010`
- glandium 9y ago> Your new password must contain 9 numbers Why is everyone assuming this means the password must only contain 9 numbers? I mean, it's very likely, but it's ambiguous enough that I was wondering if they accept other characters and want 9 numbers as well.
- taftster 9y ago> "Your new password must contain 9 numbers, and include at least 4 different numbers but cannot include the same number more than three times." Talk about reduction of password entropy.
- notacoward 9y agoThere is a silver lining here. It practically eliminates the possibility of reusing a password from another site ... because nobody else is stupid enough to have rules like these. At least when somebody cracks your password here it won't do them any good anywhere else.
- copperx 9y agoIf this site is used often enough, the password will be eventually used for other sites.
- snug 9y agoNot if my password is 123456789
- wrycoder 9y agoWe're sorry, that password is already in use.
- eat_veggies 9y agoWe're sorry, user "wrycoder" is already using that password.
- pcorey 9y agoPSA: Passwordless authentication is a valid and easy-to-implement authentication technique: http://www.east5th.co/blog/2017/04/24/passwordless-authentication-with-phoenix-tokens/ http://www.east5th.co/blog/2017/04/24/passwordless-authentic... https://auth0.com/passwordless https://auth0.com/passwordless
- c22 9y agoAnother PSA: SMS and email are both less secure channels than your average https login. My doctor doesn't trust these channels to communicate my test results, so I guess don't use this for anything more sensitive than that.
- kedwards 9y ago9 digits. I wonder what fraction of these passwords are SSNs
- resf 9y agoSince Devon is in the UK, presumably very few.
- eam 9y agoI also hate ADP's password requirements: > Your password must be 8 to 20 characters and may include upper or lowercase letters (A-Z and a-z), numbers (0-9), spaces (except at the beginning or end), and special characters. You must use at least one letter and one number. You cannot use the same character in four or more consecutive positions (for example, AAAa is valid, but AAAA is not valid) and you cannot use four or more sequential characters, in ascending or descending order, in a row (for example, ABCD and 4321 are not allowed). It almost feels like a riddle... Because I have to choose a complicated password that I can't remember, every single time I go back (maybe twice a month) I pretty much have to use the password reset functionality and make another non-memorable password. Even setting up the password takes some thinking as you can read the requirements that you have to conform with. Ugh. It's pretty annoying.

- falcolas 9y agoNote the "pronounceable" caveat in the original message. Still important to note, but the implementation above is not at risk.
- peterwwillis 9y ago> Please do not use the browser back button, only use the Back button at the bottom of the page. This amazes me a lot more than a ridiculous password scheme. You can always come up with a justification for a stupid password scheme. But there's no justification for "I don't know how sessions work" after 20 years of web development history. It was the #1 most frequent developer mistake IN 1999. https://www.nngroup.com/articles/the-top-ten-web-design-mistakes-of-1999/ https://www.nngroup.com/articles/the-top-ten-web-design-mist...

- dawnerd 9y agoOh please add it here: https://github.com/duffn/dumb-password-rules https://github.com/duffn/dumb-password-rules
- logicallee 9y agopfff. the Satan of that hell needs to be fired. I could do WAY better: " Your password must conform to the following rules: - It must be exactly 6 characters - The first character must be @ or # - The second character must be a digit except 0. - The third character must be a lowercase, uncommon letter. Uncommon letters are q, x and z. - The fourth character may be any uppercase vowel, with the exception of U. Y is not considered a vowel. - The fifth character must be a lowercase letter differing from the third character. - The sixth character must be an underscore (_). Your password must be changed after every third log-in. You may not use any of your previous ten passwords nor any password you have used in the past 180 days.
- justin_oaks 9y agoI wrote a program to check how many 9 digit numbers met the criteria. The answer I got was 897,674,400. I used the following Java code, which may be flawed, to count: public static void main(String[] args) throws Exception{ int count=0; int[] digitCount=new int[10]; mainLoop: for(int i=0; i<=999999999; i++){ Arrays.fill(digitCount,0); digitCount[i / 1 %10]++; digitCount[i / 10 %10]++; digitCount[i / 100 %10]++; digitCount[i / 1000 %10]++; digitCount[i / 10000 %10]++; digitCount[i / 100000 %10]++; digitCount[i / 1000000 %10]++; digitCount[i / 10000000 %10]++; digitCount[i / 100000000 %10]++; int differentNumbers=0; for(int index=0; index<10; index++){ if(digitCount[index]>3){ continue mainLoop; } if(digitCount[index]>0){ differentNumbers++; } } if(differentNumbers>4){ count++; } } System.out.println("count: "+count); }
- schoen 9y agoGood call on the leading zeroes. I was trying to write a Python program to do the same and I would have implicitly ignored leading zeroes, which should be considered here because a password could be, for example, 000123456.
- ThrustVectoring 9y agoThe analytic solution also isn't particularly difficult, just tedious to work through by hand. There's 10 valid ways to choose the first digit. You either repeat that digit one or zero times. If once, there are 8 ways to do this, and then you have the same sub-problem except with 9 remaining characters to use and 7 remaining places to fill. If none, there's one way to do it, and then you have the same problem except with 9 remaining characters to use and 8 remaining places to fill.
- soneil 9y agofwiw, I'd start the loop at i=1000000, on the assumption that anything less is going to fail the "three digits" test once zero-padded. A bit silly granted, but it'll let you ditch half the zero-padding. (Only half, but if they're going to be repeated n times, it might be worth it).
- osteele 9y agoOn the plus side: The web site not only has a text size selector – there also is a “Text Only” link that does exactly what it says, and reveals a “Colour Scheme” menu: Black on white, black on cream, white on blue, yellow on black. Some dev has been having fun with this while all the product people are away. As a creator of useless side projects, I can relate.
- HarryHirsch 9y agoYou'd think that this is to conform to accessibility regulations, this is a British site, and the British are very strict on that front. Nothing wrong with high-contrast schemes especially when you have cataracts.

- flukus 9y agoThis should be a browser feature and not a site feature. It kind of is with reader mode.
- twunde 9y agoI can't wait until NIST finalizes their new password rules. I wonder how many companies are forced into these inane password rules because of compliance requirements

- NamTaf 9y agoAt least it's served via HTTPS?
- NamTaf 9y agoMy bank is almost as awful: To change your Internet Banking password, please enter your current password and then enter your new password to confirm. Password requirements: Must be between 6 and 8 characters and can contain letters, numbers or both Will be case sensitive so check your caps lock Can't contain special characters (eg. $%&#) or spaces Can't be your Customer ID Can't contain consecutive numbers (eg. 123456) Shouldn't contain part of your name, date of birth, drivers licence or anything that would be in your wallet
- hughes 9y agoFind and ridicule many other examples here: http://password-shaming.tumblr.com/ http://password-shaming.tumblr.com/
- normalocity 9y agoYeah - guessing after reading that, nearly everyone's password is 123456789 If you can figure out what they use for user IDs (emails, or perhaps another 9-digit number), you'll own all these user accounts. This is what happens when cleverness meets ignorance of security.
- tmrmn 9y agoJust reminded me of the new rules set by my University. I had a really hard time coming up with one. Password needs a minimum of 10 digits. Low and upper characters, at least 2 numbers and could include special characters. These chars are not allowed: ! & ' ` $ % ; § ~ ^ @ \ € ä ö ü ß. It will be checked against last two former passwords and it couldn't be include 3 or more identical characters. Theres not many spacial characters left. Also this is a german University and äöüß are not allowed.
- BenjiWiebe 9y agoWhy don't websites say something like this: Your password must be 6 or more characters long. Any character goes. If you use a weak password and your account gets hacked, it's your fault. And then maybe have a brief explanation of what makes a password weak, but let the user decide if they want to get hacked or not.
