About

The AWS Security Token Service (STS) is a web service that enables you to request temporary limited-privilege credentials for:

• AWS Identity and Access Management (IAM) users
• or for users that you authenticate (federated users).

These credentials can then be used to call the AWS API. When a user successfully authenticates, you got a JWT as credentials.
