# Create global keys to use with all of your Ada APIs

Until now, if you've used multiple Ada APIs, you've had to create and manage different keys for each one. Now, you have the option to create one or more global keys that work across all of Ada's current and future platform APIs.

All of your existing API-specific keys will continue to work, and will still be specific to the APIs they were originally generated for. They'll be marked as legacy keys in your dashboard, so you can tell them apart from your global keys.

For more information, see [Authorize API integrations](/reference/introduction/authentication) in our Developer Docs.
