When attempting to login with an invalid username, you get the error message "Invalid username".
When attempting to login with a valid username & invalid password, you get the error message "Invalid password".
I can't think of any website which gives this kind of feedback to someone attempting to login of which of the username/password fields are incorrect. This would allow an attacker to keep guessing usernames and Filerun to tell them if they are valid or not.
In my opinion, if any part of the username/password are invalid, it should give the same login error to the user so there is no indication what part of the credentials are incorrect.
