AWS services require that you provide credentials when you access them. The console requires your password. You can create access keys for your AWS account to access the command line interface or API. However, it is not recommended to access AWS using the credentials for your AWS account. Use [[#IAM_.28AWS_Identity_and_Access_Management.29|IAM]] instead.

To create an AWS account, go to http://aws.amazon.com, and then click Sign Up.
 
For more details see http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/get-set-up-for-amazon-ec2.html.
 
=IAM (AWS Identity and Access Management)=
 
AWS Identity and Access Management is a web service that enables Amazon Web Services (AWS) customers to manage users and user permissions in AWS. The service is targeted at organizations with multiple users or systems that use AWS products such as Amazon EC2, Amazon RDS, and the AWS Management Console. With IAM, you can centrally manage users, security credentials such as access keys, and permissions that control which AWS resources users can access.
 
Without IAM, organizations with multiple users and systems must either create multiple AWS accounts, each with its own billing and subscriptions to AWS products, or employees must all share the security credentials of a single AWS account. Also, without IAM, you have no control over the tasks a particular user or system can do and what AWS resources they might use.
 
IAM addresses this issue by enabling organizations to create multiple ''IAM users''.
 
 
=IAM User=
 
An ''IAM user'' is a person, system, or application who can use AWS products, each with individual security credentials, all controlled by and billed to a single AWS account. With IAM, each user is allowed to do only what they need to do as part of the user's job.

=API Access Keys=
 
Each [[#IAM_User|IAM user]] has a set of API access keys. These keys are needed when the user attempts to make programmatic calls to AWS or EC2, using [[Amazon EC2 CLI]] tools for example. The user can create, modify, view and rotate these access keys.
 
There are two types of access keys:
 
# '''Access key ID''' (example <tt>AKIAIOSFODNN7EXAMPLE)</tt>)
# '''Secret access key''' (example: <tt>wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY</tt>)
 
When creating an access key, IAM returns the access key id and the secret access key. The secret access key is only accessible at the time it was created. If the secret access key is lost, the corresponding access key must be deleted and recreated.

The access keys can be managed here: https://console.aws.amazon.com/iam/home?#security_credential by navigating to Users -> username -> Security Credentials -> Access Credentials.
 
More about access keys for IAM users: http://docs.aws.amazon.com/IAM/latest/UserGuide/ManagingCredentials.html
 
For details on how access keys can be set in the local environment, see [[Amazon EC2 CLI Installation#Set_the_Access_Keys|Setting the Access Keys during Amazon EC2 CLI Installation]].
