Need to store customer's API keys in Bubble app

How can I securely store sensitive data (API keys of my customers) in Bubble?
I’ve heard about environment variables, but have no idea how to implement them.


If you are building an app, you can go to “Data” tab and then “Privacy” to define who should be able to read data (like the API keys of your customers).

If you are building a Plugin, you can go to the “Shared” tab and define your keys there or pass them in as arguments from an app in “Actions” or “Element Actions”.
