Fix error 1045. Default passwords for XAMPP and MAMP, and how to log in on Linux where root uses socket login.

MySQL error 1045 means the username or password was rejected. The right login depends on your setup, so check the defaults below first.

sudo mysql

Create a normal user (inside MySQL)

CREATE USER 'app'@'localhost' IDENTIFIED BY 'Change-me-123';
GRANT ALL PRIVILEGES ON appdb.* TO 'app'@'localhost';
FLUSH PRIVILEGES;

Your app still gets access denied: The username and password in your app’s config must match exactly. Check the .env or wp-config.php file.
phpMyAdmin cannot log in: If you changed the root password, update config.inc.php in the phpMyAdmin folder.
Forgot the root password: Stop MySQL, start it with --skip-grant-tables, log in, set a new password, then restart normally. Only do this on your own computer.
Use a separate user: Create one user per project instead of using root everywhere. See the .env generator.
