Configure External or Delegated Credentials

Delegated credentials let you authorize Flashgate using provider-native IAM identities and short-lived tokens instead of long-term static secrets.

In practice, this means:

• Cloud Storage: grant access via provider IAM roles/policies at bucket/container scope.

• AI/LLM: use provider-native identity flows (assumed roles, service accounts, managed identities, token exchanges) and pass endpoint + secret/token to Flashgate's existing AI LLM configuration model.

When to prefer delegated access

Use delegated access when you want stronger security controls in production:

• avoid long-lived keys where possible,

• centralize permissions in cloud IAM,

• enforce least privilege at narrow scope,

• rotate or expire credentials automatically,

• improve auditability via cloud provider logs.

Flashgate configuration still uses product fields documented in Configure an AI LLM and Configure a Bucket. Delegated patterns in this section explain how to produce credentials/tokens securely on the provider side.

Delegated Credentials for Cloud Storage

Provider	Description
Amazon Web Services (S3)	Configure delegated external access using IAM role assumption patterns.
Google Cloud Platform (GCS)	Configure delegated external access using service-account impersonation.
Microsoft Azure (Blob)	Configure delegated external access using Entra ID and RBAC role assignments.

Delegated Credentials for AI / LLM (Cloud-hosted providers)

Provider	Description
AWS Bedrock	Use IAM role assumption and short-lived credentials for Bedrock invocation flows.
GCP Vertex AI	Use service accounts and short-lived OAuth tokens (or workload identity) for Vertex AI.
Azure OpenAI	Use Entra ID/RBAC or provider keys, then configure endpoint + secret/token in Flashgate.

Security recommendations

• Grant only required actions (read-only, write-only, or specific inference scopes).

• Prefer short-lived tokens over static keys in production.

• Use separate identities for environments (dev, staging, prod).

• Monitor provider audit trails (CloudTrail, Cloud Audit Logs, Azure Activity/Diagnostic logs).

• Review and rotate trust relationships and role assignments regularly.
