Can't access PHPadmin

because don’t have a password, is there any way to retrieve my data.
I am used to other hosting provider that doesn’t require password to access php admin once you’re logged into your account

Your DB user name and password shows up in the panel under MySQL Databases. Click on the username and it’ll show you its access privileges and password.
