Introduction

AWS sts: Assume-role returns temporary security credentials, like ID/Password or one-time entry key that one can use to access Amazon Web Services resources. These temporary credentials can include an access key ID, a secret access key, and a security token. As the AWS STS Assume Role Example illustrates, one uses AssumeRole within your account or cross-account access.

As depicted in the below AWS STS Assume Role Example, the temporary security credentials created by AssumeRole can be used to make API calls to any Amazon Web Services with some exceptions:

- You cannot call the STS GetFederationToken API Operations
- You cannot call the GetSessionToken API Operations

1. Understand the AWS STS Assume Role in detail

The user account administrator delegates the permission to the user who wishes to access a role in a different account. Upon requesting access to Amazon resources, the admin is compelled to attach a policy that lets the user call the AssumeRole for the ARN of the role in the other account.

- An account admin has to attach a policy to the user
- An account admin adds the user as a principal directly in the role's trust policy

In simpler words, sts:AssumeRole action is how temporary credentials are obtained. Several organizations use it where a user or application calls the API using some already-obtained credentials and returns a new set of credentials to act as the role.
