Sign in with MySQL/MariaDB credentials directly instead of app username

[timint]

What problem are you trying to solve?

Hi. Love the attempt of making a drop in replacement for phpMyAdmin.

I'm missing the most crucial drop in replacement to ask the user for the mysql/mariadb credentials during login rather than Ledger app username password. I understand that's not possible, but that would be making this a true drop in replacement.
