DevOffline I can’t remember if XAMPP uses MySQL or MariaDB because I use WAMP, but, typically speaking the default username is typically “root” with the password field being left empty. I don’t really create my own user when doing things locally because my ports are typically closed locally for obvious reasons 😁 (though I probably should start creating my own dedicated user out of habit for the future 🤔)
As far as port goes, XAMPP will tell you what port it’s using for the DB in your XAMPP control panel within the app itself. As far as DB host goes it’s typically set as “localhost” if I’m not mistaken.
