What is Single Sign-on?

Single Sign-On (SSO) is a user authentication process that allows a user to access multiple applications with one set of login credentials (such as a username and password). This means that the user needs to log in only once and can use various services without the need to authenticate again at each of them.

Example: A common example of SSO is Google’s authentication system. When you log into your Google account, you can access various Google services like Gmail, Google Drive, Google Calendar, and YouTube without needing to log in separately for each service.

Benefits of Salesforce Single Sign-On (SSO)

Salesforce Single Sign-On (SSO) streamlines the user experience and enhances security across an organization’s Salesforce applications.

By implementing SSO, users can access all their Salesforce tools with a single set of credentials, eliminating the need for multiple passwords and reducing the likelihood of password fatigue. This simplifies the login process, improves user productivity, and reduces the time spent on password management.

Additionally, SSO centralizes the authentication process, allowing IT departments to better manage and secure user access. This centralization makes it easier to enforce robust security policies, such as two-factor authentication, enhancing overall security posture.

How Salesforce Single Sign-On (SSO) Works

Salesforce Single Sign-On (SSO) integrates with an organization’s identity provider (IdP) to authenticate users. When a user attempts to access Salesforce, the system redirects them to their IdP.

After the user logs in with their corporate credentials, the IdP verifies these details and sends a secure token to Salesforce, confirming the user’s identity.

Salesforce then grants access based on this token, allowing the user to use the platform without needing to enter separate login credentials for Salesforce. This process leverages standards like SAML (Security Assertion Markup Language) to ensure secure and seamless authentication.

Third-Party Integrations with Salesforce Single Sign-On (SSO)

  • Seamless Access Across Applications: Salesforce SSO allows users to access not only Salesforce but also various third-party applications integrated with their Salesforce environment. This seamless access enhances user productivity by reducing the number of logins required.
  • Standardized Protocols: Salesforce SSO supports standardized authentication protocols such as SAML 2.0, OAuth, and OpenID Connect, which facilitate secure and straightforward integration with a multitude of third-party services and applications.
  • Enhanced Security and Compliance: Integrating third-party applications with Salesforce SSO centralizes the authentication process, which helps enforce consistent security policies across all applications. This centralization is crucial for maintaining compliance with security standards and regulations.
  • Customizable User Experience: Organizations can customize the login and user authentication experience across integrated applications, ensuring a consistent and branded experience that aligns with corporate standards.
  • Efficient Administration: Admins benefit from the centralized management of user access and credentials, which simplifies the administrative burden associated with managing multiple separate authentication systems across various applications.

Frequently Asked Questions (FAQs)

  1. What is Salesforce SSO? Salesforce Single Sign-On (SSO) is an authentication service that allows users to access multiple authorized network resources, including Salesforce applications, with a single set of login credentials (such as username and password). This system simplifies the user experience by reducing the number of times a user has to log in to access various applications and services integrated with Salesforce.
  2. How to enable SSO in Salesforce? To enable SSO in Salesforce, follow these general steps:
    • Choose an Identity Provider (IdP): Select an IdP that supports SAML 2.0 or another supported protocol like OAuth or OpenID Connect.
    • Configure the IdP with Salesforce: Set up a connection in Salesforce by navigating to the ‘Single Sign-On Settings’ under Setup. Here, you will create a new SSO setting and input the necessary details such as the IdP’s entity ID, SSO URL, and the X.509 Certificate from the IdP.
    • Set up Domain Management: Implement My Domain in Salesforce to use custom domains, which is a prerequisite for setting up SSO.
    • Configure User Profiles: Assign the SSO-enabled profile to users who will use SSO to log into Salesforce.
    • Test the SSO Configuration: Before going live, test the SSO setup to ensure that users can authenticate via the new system without issues.
  3. Will Salesforce enforce MFA for SSO? Salesforce strongly recommends the use of Multi-Factor Authentication (MFA) to increase security, especially when using SSO. While Salesforce itself does not enforce MFA for SSO, organizations are advised to configure their IdP to require MFA. This setup ensures that even if SSO is used, the authentication process is secured by an additional layer of validation beyond just username and password. Starting February 1, 2022, Salesforce requires customers to use MFA for accessing Salesforce products to enhance security measures, which indirectly encourages MFA use with SSO configurations.
  4. How do you update an SSO certificate in Salesforce? Updating an SSO certificate in Salesforce involves a few key steps:
    • Navigate to Single Sign-On Settings: From Setup, go to the ‘Single Sign-On Settings’ and select the SSO setting you want to update.
    • Update Certificate Details: Click on ‘Edit’ and replace the old certificate with the new certificate details. This includes uploading the new certificate file (usually a .crt or .pem file) provided by your Identity Provider (IdP).
    • Save Changes: After updating the certificate and any other necessary settings, save your changes.
    • Communicate with Users: Inform users of the change as there may be a brief period when SSO is not available due to the update.
    • Test the New Configuration: Always test the new settings with a test user account to ensure that the SSO login process works seamlessly with the updated certificate.
  5. What are the advantages of Single Sign-On (SSO) in Salesforce?
    • Simplified Access Management: Users log in once and gain access to multiple systems without being prompted to log in again at each of them.
    • Increased Productivity: Reduces the time users spend entering passwords for multiple applications, leading to a more streamlined workflow.
    • Enhanced Security: Reduces the likelihood of password fatigue from managing multiple credentials, which can lead to weaker security practices. It also centralizes the control of user access, making it easier to implement security measures like MFA.
    • Improved User Experience: Provides a smoother, more integrated experience across various applications, enhancing user satisfaction and efficiency.
    • Reduced IT Costs: Decreases the need for IT support for password resets and account lockouts, as users manage fewer passwords.
  6. What is the difference between SAML and OpenID in Salesforce SSO?
    • SAML (Security Assertion Markup Language): SAML is an XML-based standard used to exchange authentication and authorization data between an identity provider and a service provider. In the context of Salesforce, SAML is used for web-based applications to allow secure, cross-domain communication between Salesforce and other services.
    • OpenID Connect: OpenID Connect is a simple identity layer on top of the OAuth 2.0 protocol. It allows clients to verify the identity of the end-user based on the authentication performed by an authorization server, as well as to obtain basic profile information about the end-user in an interoperable and REST-like manner. In Salesforce, OpenID Connect can be used for mobile and web applications, providing a more flexible and simpler way to implement SSO compared to SAML.

To determine if Single Sign-On (SSO) is enabled in Salesforce, you can follow these steps:

  1. Log into Salesforce: Use your administrator credentials to log into your Salesforce account.
  2. Navigate to Setup: Click on the gear icon in the upper right corner of the Salesforce interface and select “Setup” from the dropdown menu.
  3. Access the Single Sign-On Settings:
    • In the Quick Find box, type “Single Sign-On Settings” and select it from the dropdown results.
    • This page will display if any Single Sign-On settings are configured and active.
  4. Review SSO Configurations:
    • On the Single Sign-On Settings page, you can see all SSO configurations that have been set up.
    • Check for any configurations listed as “Active” to confirm if SSO is enabled.
  5. Inspect Specific SSO Details:
    • For each active SSO configuration, you can view details such as the SSO method (e.g., SAML), the identity provider used, and the status of the configuration.
    • If there are multiple SSO configurations, they will be listed here, and you can identify which are enabled and in use.

Understanding the terminology related to Single Sign-On (SSO) is crucial for effectively implementing and managing SSO systems. Here are some key terms and concepts commonly associated with SSO:

1. Identity Provider (IdP)

The Identity Provider is a service that stores and verifies user identities. It is responsible for providing authentication services to other services (relying parties) using SSO. The IdP sends a token or assertion to the service provider that indicates a user has been authenticated.

2. Service Provider (SP)

The Service Provider is a system that offers services to users, relying on an Identity Provider to authenticate those users. In the context of Salesforce, Salesforce itself acts as the Service Provider when it trusts an external IdP to authenticate users.

3. SAML (Security Assertion Markup Language)

SAML is an XML-based standard used to exchange authentication and authorization data between an IdP and a SP. It is one of the most commonly used protocols for implementing SSO, allowing secure cross-domain communication.

4. OAuth

OAuth is an open standard for access delegation commonly used as a way for Internet users to grant websites or applications access to their information on other websites but without giving them the passwords. It is often used in SSO implementations to authorize services without sharing credentials.

5. OpenID Connect

OpenID Connect is a simple identity layer on top of the OAuth 2.0 protocol, allowing for the authentication of end-users and the conveying of user profile information in a REST-like manner. It’s a more modern alternative to SAML, used primarily in mobile and web applications.

6. Assertions

Assertions are statements about a user’s identity or attributes, such as the user’s email address or authorization level, provided by the Identity Provider to the Service Provider. These are used by the SP to make access decisions.

7. Federation

Federation is the practice of linking together different identity management systems. In the context of SSO, federation allows the sharing of identity information across disparate systems and organizational boundaries, enabling users to authenticate across networks owned by different organizations.

8. Token

A token is a small piece of digital data used to facilitate the SSO process. After a user is authenticated by the IdP, a token is generated and sent to the SP. This token acts as proof of authentication that the SP trusts to grant access to the user.

9. Session

A session refers to the period of activity between a user and a service provider after the user has been authenticated via SSO. The session typically lasts until the user logs out or the session expires.

10. Multi-Factor Authentication (MFA)

Multi-Factor Authentication is an additional layer of security that requires more than one method of authentication from independent categories of credentials to verify the user’s identity for a login or other transaction. It is often recommended to be used alongside SSO to enhance security.
