authentication

Flow will be configured and will authenticate using the same methods defined by aws-cli.

Currently it supports authentication with:

• A EnvProvider which retrieves credentials from the environment variables of the running process. Environment credentials never expire. Environment variables used:

  • Access Key ID: AWS_ACCESS_KEY_ID or AWS_ACCESS_KEY

  • Secret Access Key: AWS_SECRET_ACCESS_KEY or AWS_SECRET_KEY

• A SharedCredentialsProvider which retrieves credentials from the current user's home directory, and keeps track if those credentials are expired.

  Profile ini file example: $HOME/.aws/credentials

• A AssumeRoleTokenProvider with enabled SharedConfigState which uses MFA prompting for token code on stdin. Go to session doc for more details.
