Reacting to Auth Events using Stitch Triggers | MongoDB Blog` Reacting to authentication events has become easier with the addition of authorization triggers in MongoDB Stitch. These triggers allow developers to execute functions based on specific authorization events such as user creation, deletion, and login. With authorization triggers, developers can automate tasks like updating user data in a collection without having to write complex code. The example provided demonstrates how to use authorization triggers to update a user's profile information after they log in or create an account, making it easier to manage user data in a secure manner.
