 API keys are unique identifiers necessary to use the [Scaleway API](https://www.scaleway.com/en/developers/api/). You can generate API keys for yourself or for an [IAM application](/iam/concepts/#application) via the Scaleway console. Each API key is scoped to one [Organization](/iam/concepts/#organization) only (so if you are part of multiple Organizations, you will need a different API key for each one). Each user and application can have multiple API keys in each Organization.
