Does it make sense for a rest service to use user authorization using mysql?

Question

MySQL

hello, I'm developing a small rest-service. I wanted to know if it is technically possible to check user rights to access data using the built-in authentication in mysql or another relational database. To what extent would such an option be acceptable and safe?

Answer 1

is it technically possible to check user rights

Well, yes.
How fast and safe it will be depends on your code.
