How to change API key of MongoLab user account
Each user of your MongoLab account has an API key by which client code can access MongoLab resources via REST API. To regenerate or change this key, you …
1. Log into MongoLab.
2. Click Account.
3. Under the Account User tab, click the user of the API key to change.
4. At the bottom of the page, click the “Regenerate API key” button.
5. A prompt asks you if you are sure. This can not be undone. And client code that is using your existing key will no longer work; they will have to use the new key. If you are sure, click regenerate.
