Check login with arrays

Question

Hello! I am trying to make a code that allows checking if a given email and password are within certain arrays, so far this code works, however I can’t make the code detect errors like: if the email is in the array but does not match the password, thus releasing an Alert.

function Entrada_login() {
            var password = document.getElementById("Password").value;
            var email = document.getElementById("Email").value;
            for (var i = 0; i < emails.length; i++) {
                if ((email == emails[i]) && (password == passwords[i])) {
                    i = i;
                    alert("funciona");

                    break;
                }
            }
        } 

Thank you!!

You can’t just add one else if? For example:

function Entrada_login() {
    var password = document.getElementById("Password").value;
    var email = document.getElementById("Email").value;
    for (var i = 0; i < emails.length; i++) {
        if ((email == emails[i]) && (password == passwords[i])) {
            i = i;
            alert("funciona");

            break;
        } else if ( (email == emails[i]) ) {
            i = i;
            alert("achou o email mas a senha nao confere");

            break;
        }
    }
}
