Each provider may need optional authentication. This might be a persistent API key, a short-lived OAuth2
access token or a refreshable OAuth2 token. There is a single credential for each provider instance.
Credentials are ephemeral -- they may be purged after the specified TTL.
Credentials are associated with the same ABAC access attributes and permissions as other
resources in the system.
Credentials are associated with the logged in user. If no user is logged in, the credentials
are associated with the anonymous user.
It is recommended to store these credentials using Envelope Encryption. The storage could
be a regular KVStore, but you should use a secure Key Management Service for encrypting
