Proper authentication responses

Summary​

System responses to authentication failures must not indicate which part of the authentication was incorrect.

Description​

Authentication forms are one of the most publicly accessible parts of an application, which makes them more susceptible to be attacked. Most authentication mechanisms require only a username and a password. If the responses to authentication attempts indicate which authentication parameter was incorrect, attackers may be able to obtain a list of valid usernames (user enumeration) that they can use in brute force attacks.
