Register & Login Page (custom authentication) | Firebase v9 | Javascript 

ATTENTION: BUG: there is a bug in this code which lets the user sign in, with just the username. REASON: code decrypt the password with passwordInp's value as key, so if you keep the passInp value empty then it will get decripted wrong and decrypting password function ends up return empty string. Solution: function AuthenticateUser() { let user = document.getElementById('userT').value; let pass = document.getElementById('passT').value; if (isNullOrWhiteSpaces(user) || isNullOrWhiteSpaces(pass)) { alert("cannot leave username/password field empty"); return; } const dbRef = ref(db); get(child(dbRef, 'UsersList/' + user)).then((snapshot) => { if (snapshot.exists()) { let dbpass = decPass(snapshot.val().Password, pass); if (dbpass == pass) { login(snapshot.val()); } else { alert("username or password not valid"); } } else { alert("username or password not valid"); } }); } function isNullOrWhiteSpaces(value) { value = value.toString(); return (value == null || value.replaceAll(' ', '').length < 1); }
