Login Failure Message Best Practice
error message is better when users entered a wrong password? up vote 3 down vote favorite Is there any differences between the following two error messages from security point of view when users entered a wrong password? Wrong username or password. Wrong password. For example, when you enter a wrong password on the Gmail.com, it will tell you "The username or password you error message for password length entered is incorrect". Is there any considerations for security reasons? I think the error message: "The password you entered is incorrect" is more clear to users, And, What's more, it's very easy to check whether a username is exists on the Gmail.com: just click "Can't access your account?" and enter the username. If the username doesn't exists, it will tell you. login passwords security share|improve this question asked Feb 17 '13 at 14:30 luin 764818 1 I'm sure if you tried the "can't access your account" trick a few thousand times it'd soon be noticed. –Paul Collingwood Feb 17 '13 at 14:32 add a comment| 3 Answers 3 active oldest votes up vote 7 down vote accepted The idea is to not give hackers extra information. If you say wrong password, you've told a hacker that they have a correct username, and vice-versa. Although what you've said is true, on some sites it is possible to determine if you've guessed a username via other means. share|improve this answer answered Feb 17 '13 at 14:33 Mike C. 2,2361814 add a comment| up vote 2 down vote In some cont

it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top Generic error message for wrong password or username - is this really helpful? up vote 60 down vote favorite 15 http://stackoverflow.com/questions/14922130/which-error-message-is-better-when-users-entered-a-wrong-password It is really common (and I would say it is some kind of security basic) to not show on the login page if the username or the password was wrong when a user tries to log in. One should show a generic message instead, like "Password or username are wrong". The reason is not to show potential attackers which usernames are already taken, so it'll be harder to 'hack' an existing account. Sounded reasonable for me, but then something different came http://security.stackexchange.com/questions/62661/generic-error-message-for-wrong-password-or-username-is-this-really-helpful on my mind. When you register your account, you type in your username. And when it is already taken, you get an error message - which is not generic! So basically, an attacker could just grab 'correct' user names from the register page, or am I wrong? So what is the point about generic messages than? Non-generic messages would lead to a much better UX. passwords authentication share|improve this question asked Jul 7 '14 at 19:41 verbose-mode 403158 3 There are sites like Yahoo mail for example, where enter the right username and incorrect password gives the generic message. On entering "Incorrect Username" it gives a message "This username is not taken ..." so much for security. I think this is a relic from old days and does not have place in today's scheme of things. –Dheer Jul 8 '14 at 6:47 Additionally, when you mistype your password on the Win7 lockscreen (where the username is preselected by default) you still get the generic message... –Nicktar Jul 9 '14 at 11:54 2 I prefer the "Forgot password" function, which also tells me if the username is valid or not in many cases. The link is usually near the password field, no need to go the "Register" detour. –basic6 Jul 9 '14 at 14:57 add a comment| 9 Answers 9 active oldest votes up vote 51 down vote accepted No, you are correct that at some point
