Question

Warning: mysqli_connect(): (HY000/1045): Access denied for user \'username\'@\'localhost\' (using password: YES) in C:\\Users\\xampp\\htdocs\\PHP_Login_Script

Answer 1

Make sure that your password doesn't have special characters and just keep a plain password (for ex: 12345), it will work. This is the strangest thing that I have ever seen. I spent about 2 hours to figure this out.

Note: 12345 mentioned below is your plain password

GRANT ALL PRIVILEGES ON dbname.* TO 'yourusername'@'%' IDENTIFIED BY '12345';
