Access bubble data from seperate application

Suppose I want to create a website with bubble, and a mobile application myself from scratch. I need to be able to register and log in the same set of users on both my app and bubble, and access other data associated with user accounts. Is this possible with bubble’s built in database, or am I better off running my own SQL database and connecting with the SQL database connector.

Bubble API Connector plugin should work just fine. You can find more details by searching through the forum.
