AWS Okta Keyman

This is a simple command-line tool for logging into Okta and generating temporary Amazon AWS Credentials. This tool makes it easy and secure to generate short-lived, logged and user-attributed credentials that can be used for any of the Amazon SDK libraries or CLI tools.


Key features listed here. Keep scrolling for more details.

  • MFA support
  • Multiple AWS role support
  • Automatic reup/refresh mode
  • Dynamic AWS/Okta integration list
  • Automatic username selection
  • Okta password caching
  • Command wrapping
  • Screen/shell only output
  • GovCloud support
  • Adjustable key lifetime
  • Console login URLs
  • Config files
  • Interactive config generation
  • Installation via pip and Homebrew
  • Linux, Windows, and OSX support

Benefits vs other similar tools:

  • Runs without external dependencies; no servers or lambdas required
  • No API keys required; just your Okta username and password
  • No analytics or metrics collection; this tool does not call home in any way
  • Open source distributed as source; you can see what you're running
  • Wide Python version support; works on Python 3.6+

Optional MFA Authentication

If your organization or integration requires MFA we will automatically detect that requirement during authentication and prompt the user to complete the Multi Factor Authentication.

In particular, there is support for standard passcode based auth, as well as support for Okta Verify with Push and Duo Auth. If both are available, Okta Verify with Push will be prioritized and a push notification is automatically sent to the user. If the user declines the validation, then optionally the Passcode can be entered in manually.

For Duo Auth Duo wants you to use a web page to load their iframe to pick your factor and then move forward from there. That is one option and the one most likely to keep working. This tool now also has an alternative browserless option that attempts to use Duo for MFA without a browser. This may eventually be stopped/prevented by Duo but makes this tool work on remote servers or in any other case where you may not be able to use a browser.

Supported MFA Solutions

  • Okta Verify
  • Duo Auth (push, call, or OTP via CLI)
  • Duo Auth (push, call, or OTP via web browser)
  • Okta OTP
  • Google Auth OTP
  • Call OTP
  • Question/Answer

Windows Hello, U2F, email, and physical token (RSA, Symantec) are not supported at this time.

Multiple AWS Roles

AWS Okta Keyman supports multiple AWS roles when configured. The user is prompted to select the role they wish to use before the temporary keys are generated.

Re-Up Mode .. Automatic Credential Re-Generation

Amazon IAM defaults to Federated Login sessions that last up to 1 hour. For developers, it can be painful to re-authenticate every hour during your work day. This is made much worse if your organization requires MFA on each login.

You may run the AWS Okta Keyman in "reup" mode to get around this. The tool will continue to run in a sleep loop periodically reaching out to Okta, generating a new SAML Assertion, and then generating updated Amazon AWS credentials. This can run for as long as your Okta administrator has allowed your Login Session to be - often a full work day.

In the case of application-level MFA you will be prompted every 50 minutes or so to complete the MFA again.

See the --reup commandline option for help here!

AWS Accounts from Okta

AWS Okta Keyman can pull the AWS Accounts that have been assigned from Okta itself which means the app ID value no longer needs to be provided in the command line or in the config file. A config file can still optionally be used to ensure account names or order if preferred. This means with no configuration saved you only need to provide your organization.

Automatic Username

AWS Okta Keyman will use the current user as the username for Okta authentication if no username has been provided.

Keyring Password Cache

AWS Okta Keyman can use your local keyring to store your Okta password to allow you to run the tool repeatedly without needing to type your password in each time. For details on how this is accomplished check out keyring.

aws_okta_keyman -P    # Enable the password cache
aws_okta_keyman -R    # Reset the cached password in case of mistaken entry or password change

Command Wrapping

Command wrapping provides a simple way to execute any command you would like directly from Keyman where the AWS access key environment variables will be provided when starting the command. An example of this is provided here:

$ aws_okta_keyman --command "echo \$AWS_ACCESS_KEY_ID"


14:07:17   (INFO) Wrote profile "default" to /home/nathan/.aws/credentials 💾
14:07:17   (INFO) Current time is 2020-01-10 22:07:17.027964
14:07:17   (INFO) Session expires at 2020-01-10 23:07:16+00:00 ⏳
14:07:17   (INFO) Running requested command...


Screen-only Key Output

Screen-only output for cases were the key needs to be copied elsewhere for use. This makes using the temporary keys in other apps simpler and easier. They will not be written out to the AWS credentials file when this option is specified.

$ aws_okta_keyman --screen


14:14:04   (INFO) Assuming role: arn:aws:iam::1234567890:role/Admin
14:14:04   (INFO) AWS Credentials:

AWS_SECRET_ACCESS_KEY = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
AWS_SESSION_TOKEN = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

14:14:04 (INFO) All done! 👍

GovCloud Support

AWS Okta Keyman now works with AWS GovCloud. Use the --region command-line option to specify the AWS region to get the keys from.

Preferred Key Duration

You can set a key lifetime other than the default 1 hour by setting --duration when calling Keyman. If AWS rejects the request for a longer duration the default 1 hour will be used instead. You can request key durations from a minimum of 15 minutes (900 seconds) or up to 12 hours (43200 seconds). These limits are enforced by AWS and are not a limitation of Keyman.

AWS Console Logins

AWS Console login links can optionally be generated when yo request keys with Keyman. The console login link will be output on the screen for you to use. Just provide the --console parameter when running Keyman.

Config file .. predefined settings for you or your org

The config file, which defaults to ~/.config/aws_okta_keyman.yml, allows you to pre-set things like your username, Okta organization name (subdomain), and AWS accounts and App IDs to make this script simpler to use. This also supports username assumption based on the current user when the username or email is configured as automatic-username if usernames only are an option or if you need full emails. Arguments will always be preferred to the config file so you can override what's in the config file as needed on each run of the tool.

Example config file:

org: example
  - name: Dev
    appid: exampleAppIDFromOkta/234
  - name: Prod
    appid: exampleAppIDFromOkta/345

When used you'll get a similar interface to AWS Role selection but for your AWS accounts.

Interactive Configuration

For interactive configuration and creation of the config file you can start the tool with just config as a parameter and you will be propted to provide the basic information needed to get started. An example of this is shown here:

$ aws_okta_keyman config
14:21:41   (INFO) AWS Okta Keyman 🔐 v0.7.0
14:21:41   (INFO) Interactive setup requested

What is your Okta Organization subdomain?
Example; for enter 'co'

Okta org: example

What is your Okta user name?
If it is nathan you can leave this blank.

Username: nathan.v

Next we can optionally configure your AWS integrations. This is not
required as the AWS integrations can be picked up automatically from
Okta. If you would prefer to list only specific integrations or prefer
to specify the friendly names yourself you can provide the following
information. You will be prompted to continue providing integration
details until you provide a blank response to the app ID. If you are
unsure how to answer these questions just leave the app ID blank.

What is your AWS integration app ID?
Example; 0oaciCSo1d8/123
App ID: 0oaciCSo1d8/123

Please provide a friendly name for this app.
App ID: AWS Prod

What is your AWS integration app ID?
Example; 0oaciCSo1d8/123
App ID:

14:21:58   (INFO) Config file written. Please rerun Keyman

Python Versions

Python 2.7.4+ and Python 3.5.0+ are supported.

Support for older Python versions will be maintained as long as is reasonable. Before support is removed a reminder/warning will be provided.

Troubleshooting information is available on the project Github wiki.

Okta Setup

Before you can use this tool, your Okta administrator needs to set up Amazon/Okta integration using SAML roles.


This is a hard fork of nd_okta_auth by, Inc.. I decided to move ahead this way as I wanted to be able to move quickly and add features independently of the existing implementation. A big thank you to @diranged for the original work that this comes from.

The original code is heavily based on the previous work done by ThoughtWorksInc on their OktaAuth and AWS Role Credentials tools.
