About Mysql

Mysql is one of the most popular relational databases in the market. It's open source and free to use, popular Mysql alternatives like MariaDB, Percona, and Aurora Database from Amazon are all derived from Mysql and offer full (or very near) compatibility with the original Mysql.

Security/Other Concerns

The reason you want to create custom user/password and permission grants is 1) Security: you want restrict permissions of each application to the bare minimum, this will reduce blast radius of whatever problem you may face with exploits, 2) Monitoring: different users allows you to monitor database usage per application, impose limits, debug/troubleshoot problems, pinpoint the root cause earlier.
