AWS Auth Methods

Method	How to Use
Bearer token	`AWS_BEARER_TOKEN_BEDROCK` env var or `--bearer-token`
Environment variables	Set `AWS_ACCESS_KEY_ID` + `AWS_SECRET_ACCESS_KEY`
Credentials file	Configure `~/.aws/credentials`
Named profile	`--profile my-profile` or `AWS_PROFILE` env var
Direct keys	`--access-key AKIA... --secret-key ...`
Temporary credentials	Add `--session-token` with direct keys
IAM instance role	Auto-detected on EC2/ECS/Lambda
AWS SSO	Run `aws sso login` first

Auto-detection order: direct keys → profile → bearer token → env vars → credentials file → instance role → SSO.
