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 app 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 app

Log in to the Bitwarden web app and open the Admin Console using the product switcher:

Product switcher
Product switcher

Open 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 and select SAML from the the Type dropdown. Keep this screen open for easy reference.

You can turn off the Set a unique SP entity ID option at this stage if you wish. Doing so will remove your organization ID from your SP entity ID value, however in almost all cases it is recommended to leave this option on.

tip

There are alternative Member decryption options. Learn how to get started using SSO with trusted devices or Key Connector.

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.

This automatically-generated value can be copied from the organization's SettingsSingle sign-on screen and will vary based on your setup.

Audience URI (SP Entity ID)

Set this field to the pre-generated SP Entity ID.

This automatically-generated value can be copied from the organization's SettingsSingle sign-on screen and will vary based on your setup.

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 app

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

Expect signed assertions

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 certification 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).

Allow outbound logout requests

Login with SSO currently does not support SLO.

Want Authentication Requests Signed

Whether Okta expects SAML requests to be signed.

note

When completing the X509 certificate, take note of the expiration date. Certificates will have to be renewed in order to prevent any disruptions in service to SSO end users. If a certificate has expired, Admin and Owner accounts will always be able to log in with email address and master password.

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:

Log in options screen
Log in options screen

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!

note

Bitwarden does not support unsolicited responses, so initiating login from your IdP will result in an error. The SSO login flow must be initiated from Bitwarden. Okta administrators can create an Okta Bookmark App that will link directly to the Bitwarden web vault login page.

  1. As an admin, navigate to the Applications drop down located on the main navigation bar and select Applications.

  2. Click Browse App Catalog.

  3. Search for Bookmark App and click Add Integration.

  4. Add the following settings to the application:

    1. Give the application a name such as Bitwarden Login.

    2. In the URL field, provide the URL to your Bitwarden client such as https://vault.bitwarden.com/#/login or your-self-hostedURL.com.

  5. Select Done and return to the applications dashboard and edit the newly created app.

  6. Assign people and groups to the application. You may also assign a logo to the application for end user recognition. The Bitwarden logo can be obtained here.

Once this process has been completed, assigned people and groups will have a Bitwarden bookmark application on their Okta dashboard that will link them directly to the Bitwarden web vault login page.
