How to Enable Single Sign-On on Multiple WordPress Sites?

Using a single set of credentials, users can access multiple enterprise applications with Single Sign-On (SSO), a centralized authentication and authorization method. An identity provider (IDP) is in charge of managing SSO. It verifies user identities and grants access to authorized resources. Users only need to enter their credentials once with single sign-on (SSO), which saves time and effort when logging in to multiple applications. This likewise upgrades security by limiting the gamble of password related weaknesses and breaks.

SSO is often used in a business setting when user applications are assigned and managed by an internal IT team. Additionally, SaaS-based remote workers can benefit from SSO. Using SSO also helps remote workers who use software as a service. Numerous identity and access management (IAM) or access control solutions include SSO as an important component. In order to determine which permissions each user should have, user identity verification is essential. It can lessen managerial above related with dealing with various records and passwords for every client, further develop security by decreasing the quantity of passwords that should be made due, and increment client effectiveness by diminishing how much time spent signing in to various applications.

SSO utilizing OAuth and OpenID convention?

OAuth allows clients to access server resources securely on behalf of a resource owner. This standard was created through collaboration between Google and Twitter to simplify online logins. Even if you are not aware of it, you have probably used OAuth before, as it is utilized behind the scenes when a website requests that you log in using your Google or Facebook credentials.

OAuth is a framework or open-standard authorization protocol that explains how unrelated servers and services can allow authenticated access to their assets without sharing the same initial logon credential. In authentication jargon, this is referred to as secure, third-party, user-agent, delegated authorization.

Based on the OAuth 2.0 framework, OpenID Connect (OIDC) is a free and open authentication protocol. OpenID is a framework for installing Single Sign-On for multiple WordPress sites that makes use of OAuth2. The current version is called “OpenID Connect.” It lets you select an identity provider (such as Google) to serve as your OpenID identity provider.

If a site supports OpenID, users can now log in with their nominated identity provider’s credentials, which means they just have to remember one set of security credentials. User only discloses the password to the OpenID provider, who then verifies that the user is who they say they are to the websites they visit. Your password is never seen by anybody other than your provider, and you can choose which of your data a dependent party has access to.

How can SSO be incorporated into your WordPress website?

Users no longer need to remember multiple passwords to access network resources, and multiple logins no longer slow them down. This is likewise advantageous to assist work area faculty, who willingly need to deal with less demands for failing to remember passwords.

The website offers a few SSO plugins. WordPress SSO with miniOrange OAuth & OpenID Connect plugin allows for unlimited login/SSO (Single Sign On) with any identity provider that supports the OAuth/OpenID protocol. One of the plugins that can provide you with seamless SSO with widely used Identity Provider is OAuth Single Sign On – SSO (OAuth Client). Additionally, it permits authorized users to Login and Register on the WordPress website because it supports unlimited user authentication via the OAuth and OpenID Connect protocols.

Any OAuth/OpenID-compliant Identity Provider (IdP) can be used to sign in using the WordPress Single Sign-On SSO plugin.

How to implement Single Sign-On on multiple WordPress Sites?

Single sign-on (SSO) is a common practice among large organizations that operate multiple WordPress sites. This approach can boost productivity and enhance security measures for employees and IT personnel. SSO is especially effective when used in tandem with Risk-Based Authentication (RBA), as it can reduce password fatigue and streamline the user experience. Nowadays, complex websites like subscription-based platforms and online learning portals are adopting SSO as a way to simplify access control.

If you prefer not to rely on third-party Identity Providers such as Google, Facebook or any other provider, you have the option to configure one of your websites as an OAuth server. This allows you to connect multiple clients to your designated main site. With the WP OAuth Server plugin, you can easily create a main server site that can be linked to various clients, simplifying the installation of Single Sign-On for multiple WordPress sites.

A) To enable seamless user authentication across multiple WordPress sites, consider installing the WP OAuth Client plugin on a designated “client site.” By incorporating an SSO (single sign-on) on this site, users can securely log in using their server credentials. So the user credentials will be stored at only one place, that is the WordPress server site eliminating the risk to manage users on multiple sites.

For example, if a user manages five different WordPress sites and wants to implement auto-login functionality, installing the OAuth Server plugin on one of the sites can serve as the main server site. By installing the OAuth Client plugin on the other four sites, a user who logs in to the main server site will automatically be logged in to the other four sites, streamlining the authentication process.
Additionally, users have the option to store their user data on alternative platforms, such as ReactJS, and utilize it as a server site by installing the OAuth server plugin on said platform. By installing the WP OAuth Client plugin on a WordPress site, users can establish it as a client-side interface for authenticating and facilitating automatic login for their users.

B) Also, users can keep their credentials in a centralized Identity Provider (IAM) instead of making one of the WordPress Sites as a server. This is because if anyone has a non-WordPress site or other web applications, users can use the same Identity Provider’s credentials to login into multiple applications.

Why is it recommended to have a centralized IAM to store your user credentials?

Centralized IAM allows users to access all the resources and applications with a single set of credentials. This eliminates the need to remember and maintain multiple sets of credentials for each application, which inturn improves the user experience and reduces cyber attacks.

Below are some of the benefits of enabling Identity and Access Management in your organization:

  • Easy Accessibility: IAM helps you access any platform anytime and anywhere just by his/her Identity verification.
  • Improved Productivity: Identity and Access Management automates the new entries and provides access to all the components integrated with that organization. This takes less time than manual work.
  • Centralized Access Control: IAMs are managed centrally so, implementing the IAM helps organizations strengthen their security according to the policies, configurations, and norms. After implementation of IAM, it is easy for organizations to withdraw unwanted access privileges, identify security violations, and revoke access privileges due to the centralized system and transparency.
  • Improves User Satisfaction: Identity and Access Management (IAM) significantly reduces the challenges associated with manual procedures. By leveraging automation, IAM empowers users to handle account management and requests through self-service methods, such as password resets. This allows users to select personalized and distinctive passwords according to their preferences.

Furthermore, IAM incorporates the Single Sign-On (SSO) technique, enabling users to utilize the same password across various systems within the organization. This approach effectively diminishes the burden of remembering multiple passwords, thereby minimizing security risks. As a result, once successfully implemented, IAM becomes user-friendly and straightforward for end users.
