The problem I am facing is :

I have developed a user login form. However, even when only the email part is entered incorrectly, I get the message “both your email address and password are incorrect”. When the email is entered incorrectly, I want to get a message that only the email address is incorrect.

The solution I was waiting for:

When an e-mail address is entered incorrectly, the user should only be shown an error message that the e-mail address is incorrect. Similarly, if the password is entered incorrectly, only the password error message should be shown.

The event that took place :

Currently, the message “both your email address and password are incorrect” is shown, even when only the email is entered incorrectly.
