![]() ![]() Remember to destroy any paper record once you have it memorized. Telephone number and social security number, even though they aren't Week you will have it memorized, just like you can remember your Write it down and keep it in your wallet (not on your monitor or anywhere not private). Twice, to ensure that you can type it in reliably. When picking a suggestion, do not cut and paste! Type in the password Option 2: Another option is to login to our accounts page, follow the "Set/Disable Password" link on the left hand column, and pick one of the suggestions the system offers. Note that you need to come up with your own phrase the examples above should not be used. You can pick anything you want, so it should be relatively easy to find something you can remember. Option 1: The easiest way is to use a passphrase that is more than 15 characters long. It must contain at least two types of characters (lowercase, uppercase, numbers, punctuation).It must not include your username or real name.Passwords longer than 15 characters must follow these rules:.For example, these would not be valid passwords: It must contain characters in more than one of these groups: lower case, upper case, numbers, and punctuation.It must not contain common words or substitutes.Passwords of 9 to 15 characters in length have a number of restrictions:.However, I realize that it's difficult to write a (maintainable and efficient) regular expression to check for dictionary words.Passwords must be at least 9 characters long. should point out that technically none of these passwords should be acceptable because they use dictionary words, which have about 2 bits of entropy per character instead of something more like 6. \d) into (?=.\d.*\d).įor your test cases, if you are worried that it would only check the first criteria, then write a test case that makes sure each of the following passwords fails (because one and only one of the criteria is not met in each case): Just for fun I reversed the order of expectation of each character set, though it probably won't make a difference unless someone removes/forgets the ?= at some future date. If you still have to find groups of two characters, why not just repeat each pattern? For example, make (?=. Entropy per character would depend roughly on the number of characters, the range of character sets they use, and maybe how often they switch between character sets (I would guess that passwords like HEYthere are more predictable than heYThEre).Īnother note: do you plan not to count the symbols to the right of the keyboard (period, comma, angle brackets, etc.)? I recommend counting bits of entropy and making sure they're greater than 60 (usually requires a 10-14 character password). Users will tend to get frustrated and write passwords down if they have to abide by too many password rules (which make the passwords too difficult to remember). You can get the same degree of randomness by letting people make longer passwords. Personally, I think a password policy that forces use of all three character classes is not very helpful. Matcher match = pattern.matcher(password) įrom what I see if it evaluates to true it will throw the value in password back to me else it is an empty string. Any thoughts on this? Pattern pattern = pile(regEx) The password I am using is the following string "$$QiouWER1245", the behavior I am experiencing at the moment is that it randomly chooses to pass or fail. ![]() Thanks to Ken and Gumbo on helping me with this. Well as it stands in my haste to validate the expression I forgot to validate my string length. This is for a password, however the requirement is that it needs to be in regex form based on the package we are utilizing. The question I have is how do I make it check for 2 of each of these? Also I ask because it is seemingly difficult to write a test case for this as I do not know if it is only evaluating the first set of criteria that it needs. is the regex I am currently using which will evaluate on 1 of each: upper,lower,digit, and specials of my choosing.
