Bedrock supports bearer-token authentication (via the AWS_BEARER_TOKEN_BEDROCK environment variable or programmatically) as an alternative to full AWS SigV4-signed credentials — useful in corporate environments needing Bedrock access without managing IAM roles/AWS credentials directly. Bearer-token auth is supported in the C#, Go, and Java SDKs; the PHP, Python, TypeScript, and Ruby SDKs use AWS SigV4 signing only.
