AWS - Login

The login aws command authenticates with AWS using browser-based authentication. This generates short-lived credentials backed by your AWS Console session, without requiring the AWS CLI.

serverless login aws

Options

• --aws-profile - AWS profile name to configure (defaults to default)
• --region or -r - AWS region to configure

Examples

Login and configure the default profile:

serverless login aws

Login with a specific profile and region:

serverless login aws --aws-profile myprofile --region us-west-2

How It Works

1. The command opens your browser to the AWS sign-in page
2. After authenticating with your AWS Console credentials, you're redirected back
3. Temporary credentials are cached in ~/.aws/login/cache/
4. Your AWS config file (~/.aws/config) is updated with a login_session reference

Note: Sessions expire after 12 hours. Run serverless login aws again to refresh your credentials.
