Thank you Sandip,
When a user attempts to login with a valid user name and invalid password the error message reads ERROR:The password you entered for username alice is incorrect.?Lost Your Password?
When a user attempts to login with both invalid user name and invalid password the error message reads ERROR:The password you entered for username cat is incorrect.?Lost Your Password?
It’s the same message perhaps leading the user (or a hacker) to believe that the user name is valid. When both user name and password are incorrect the message should say so. I’m not getting the error message you quoted above.
