I want to make an Android application that CRUD performs on a MYSQL database.
I've already figured out that the way to do this is to use Webservice .
I'm new to this area but I've already done a simple PHP via REST and I've been researching about them. However, so far I have not seen a Webservice that has access authorization system as a common database. That is, anyone who accesses the address of my webservice will have access to any information from my database .
I would like to know if there is any that uses a security system to not allow undue access that is more targeted to the medium I am using, in this case Android.
Edit: After reading the comments and searching and searching, I'm thinking of creating an Access Control system myself. Is it recommended or not?
