Okta SAML Implementation

This article contains Okta-specific help for configuring Login with SSO via SAML 2.0. For help configuring login with SSO for another IdP, refer to SAML 2.0 Configuration.

Configuration involves working simultaneously within the Bitwarden web vault and the Okta Admin Portal. As you proceed, we recommend having both readily available and completing steps in the order they are documented.

Open SSO in the web vault

Navigate to your organization's SettingsSingle Sign-On screen:

SAML 2.0 Configuration
SAML 2.0 Configuration

If you haven't already, create a unique SSO Identifier for your organization. Otherwise, you don't need to edit anything on this screen yet, but keep it open for easy reference.

tip

If you are self-hosting Bitwarden, you can use alternative Member Decryption Options. This feature is disabled by default, so continue with Master Password decryption for now and learn how to get started using Key Connector once your configuration is complete and successfully working.

Create an Okta application

In the Okta Admin Portal, select ApplicationsApplications from the navigation. On the Applications screen, select the Create App Integration button:

Okta create app integration
Okta create app integration

In the Create a New Application Integration dialog, select the SAML 2.0 radio button:

SAML 2.0 radio button
SAML 2.0 radio button

Select the Next button to proceed to configuration.

General settings

On the General Settings screen, give the application a unique, Bitwarden-specific name and select Next.

Configure SAML

On the Configure SAML screen, configure the following fields:

Field Description
Single sign on URL Set this field to the pre-generated Assertion Consumer Service (ACS) URL retrieved from the Bitwarden SSO Configuration screen.

For cloud-hosted customers, this is always https://sso.bitwarden.com/saml2/your-org-id/Acs. For self-hosted instances, this is determined by your configured server URL, for example https://your.domain.com/sso/saml2/your-org-id/Acs.
Audience URI (SP Entity ID) Set this field to the pre-generated SP Entity ID retrieved from the Bitwarden SSO Configuration screen.

For cloud-hosted customers, this is always https://sso.bitwarden.com/saml2. For self-hosted instances, this is determined by your configured server URL, for example https://your.domain.com/sso/saml2.
Name ID format Select the SAML NameID format to use in SAML assertions. By default, Unspecified.
Application username Select the Okta attribute users will use to login to Bitwarden.

Advanced settings

Select the Show Advanced Settings link and configure the following fields:

Advanced Settings
Advanced Settings
Field Description
Response Whether the SAML response is signed by Okta.
Assertion Signature Whether the SAML assertion is signed by Okta.
Signature Algorithm The signing algorithm used to sign the response and/or assertion, depending on which is set to Signed. By default, rsa-sha256.
Digest Algorithm The digest algorithm used to sign the response and/or assertion, depending on which is set to Signed. This field must match the selected Signature Algorithm.

Attribute statements

In the Attribute Statements section, construct the following SP → IdP attribute mappings:

Attribute Statements
Attribute Statements

Once configured, select the Next button to proceed to the Feedback screen and select Finish.

Get IdP values

Once your application is created, select the Sign On tab for the app and select the View Setup Instructions button located on the right side of the screen:

View SAML setup instructions
View SAML setup instructions

Either leave this page up for future use, or copy the Identity Provider Single Sign-On URL and Identity Provider Issuer and download the X.509 Certificate:

IdP Values
IdP Values

Assignments

Navigate to the Assignments tab and select the Assign button:

Assigning Groups
Assigning Groups

You can assign access to the application on a user-by-user basis using the Assign to People option, or in-bulk using the Assign to Groups option.

Back to the web vault

At this point, you have configured everything you need within the context of the Okta Admin Portal. Return to the Bitwarden web vault to complete configuration.

The Single Sign-On screen separates configuration into two sections:

  • SAML Service Provider Configuration will determine the format of SAML requests.

  • SAML Identity Provider Configuration will determine the format to expect for SAML responses.

Service provider configuration

Configure the following fields according to the choices selected in the Okta Admin Portal during app creation:

Field Description
Name ID Format Set this to whatever the Name ID format specified in Okta, otherwise leave Unspecified.
Outbound Signing Algorithm The algorithm Bitwarden will use to sign SAML requests.
Signing Behavior Whether/when SAML requests will be signed.
Minimum Incoming Signing Algorithm Set this to the Signature Algorithm specified in Okta.
Want Assertions Signed Check this box if you set the Assertion Signature field to Signed in Okta.
Validate Certificates Check this box when using trusted and valid certificates from your IdP through a trusted CA. Self-signed certificates may fail unless proper trust chains are configure within the Bitwarden login with SSO docker image.

When you're done with the service provider configuration, Save your work.

Identity provider configuration

Identity provider configuration will often require you to refer back to the Okta Admin Portal to retrieve application values:

Field Description
Entity ID Enter your Identity Provider Issuer, retrieved from the Okta Sign On Settings screen by selecting the View Setup Instructions button. This field is case sensitive.
Binding Type Set to Redirect. Okta currently does not support HTTP POST.
Single Sign On Service URL Enter your Identity Provider Single Sign-On URL, retrieved from the Okta Sign On Settings screen.
Single Log Out Service URL Login with SSO currently does not support SLO. This option is planned for future development, however you may pre-configure it if you wish.
X509 Public Certificate Paste the downloaded certificate, removing -----BEGIN CERTIFICATE----- and -----END CERTIFICATE-----.

The certificate value is case sensitive, extra spaces, carriage returns, and other extraneous characters will cause certifiation validation to fail.
Outbound Signing Algorithm Select the Signature Algorithm selected during Okta app configuration. If you didn't change the Signature Algorithm, leave the default (rsa-sha256).
Disable Outbound Logout Requests Login with SSO currently does not support SLO. This option is planned for future development.
Want Authentication Requests Signed Whether Okta expects SAML requests to be signed.

When you're done with the identity provider configuration, Save your work.

tip

You can require users to log in with SSO by activating the single sign-on authentication policy. Please note, this will require activating the single organization policy as well. Learn more.

Test the configuration

Once your configuration is complete, test it by navigating to https://vault.bitwarden.com, entering your email address, selecting Continue, and selecting the Enterprise Single-On button:

Enterprise single sign on and master password
Enterprise single sign on and master password

Enter the configured organization identifier and select Log In. If your implementation is successfully configured, you will be redirected to the Okta login screen:

Log in with Okta
Log in with Okta

After you authenticate with your Okta credentials, enter your Bitwarden master password to decrypt your vault!
