A Quick Guide to Single Sign-On (SSO)

A Quick Guide to Single Sign-On (SSO)

Do you have multiple accounts for different websites and applications? If so, you’re not alone. With the rise of online services, having multiple accounts has become increasingly common. However, managing all of those usernames and passwords can be a hassle. Fortunately, single sign-on (SSO) is made for this particular problem. 

This article will discuss single sign-on, how it works, and how you can start using it today!


What is Single-Sign-On (SSO)?

Single-sign-on authentication allows users to use one set of credentials to authenticate securely with multiple applications and websites. With SSO, users will only need a single username and password to access all of their online accounts. 

This level of convenience and security makes SSO a popular choice for businesses and individuals. As a result, SSO implementations are usually adopted and integrated by companies in the form of enterprise-level software. 

With the advent of cloud computing and the constant rise of SaaS (Software as a Service), many companies worldwide are shifting focus to access management strategies that enhance user experience and security. The implementation of SSO can cater to both aspects.


How Does Single-Sign-On Work?

Single sign-on works based on a trust relationship set between an application (Service Provider) and an identity provider (the user). The most common identity provider type is a directory service, such as Active Directory or LDAP. 

This trust relationship is often established by exchanging a certificate between the identity provider and the service provider. This certificate can sign identity information sent from the identity provider to the service provider. This way, the service provider can be sure that the information comes from a trusted source. 


There are two common ways to set up a single sign-on:



Federation is a method of sharing identity information between two or more systems. For example, in the context of SSO, a federation can share authentication information between an identity provider and a service provider.

The most common type of federation protocol is SAML (Security Assertion Markup Language). SAML is an XML-based protocol that enables the sharing of authentication information between systems.



A proxy is a server that serves as an intermediary between a client and another server. In the context of SSO, proxies can pass authentication information between an identity provider and a service provider.

One of the most common proxy protocols is CAS (Central Authentication Service). CAS is a server that provides single sign-on capabilities for web applications.


The SSO procedure usually looks like this:

  1. A user browses the website or application (the Service Provider).
  2. The Service Provider will then send a token containing information about the user, like their email address, to the SSO system (the Identity Provider) as part of a user authentication request.
  3. The Identity Provider will then check to see whether the user has already been authenticated, granting the user direct access to the Service Provider application (skip to step 5).
  4. However, if the user hasn’t logged in, the Service Provider will prompt them to do so by providing the right credentials required by the Identity Provider. It could simply be a username/password combination or include other forms of authentication, such as a One-Time Password (OTP).
  5. Once the Identity Provider Validates the credentials, it will send a token back to the Service Provider, confirming a successful authentication.
  6. This token is then passed on via the user’s browser and onto the Service Provider.
  7. The token the Service Provider receives is validated and verified according to the trust relationship set between the Identity Provider and Service Provider during the initial configuration.
  8. Once everything is confirmed, the user will gain access to the service provider.


Remember that every new website will have a similar trust relationship configured with the SSO solution. In addition, the authentication flow would also follow the same steps.


Is SSO Secure?

Yes, SSO is a secure way to authenticate users because it uses strong encryption methods to protect user credentials. In addition, SSO solutions are often integrated with other security solutions, such as two-factor authentication, to further secure user accounts.

However, keep in mind that there are always security risks inherent in any authentication system, so it’s important to understand the potential threats and take steps to mitigate them. When configuring an SSO solution, consult with a security expert to ensure your system is as secure as possible.


How To Implement SSO?

Implementing SSO for your business or organization can have potential drawbacks. However, they will give your users a better experience and make your life as an administrator much easier. When you’re ready to implement SSO, there are a few things that you should keep in mind:


Choose The Right SSO Solution

Not all SSO solutions are created equal. When choosing an SSO solution, consider your organization’s specific needs and requirements.


Set Up A Secure Connection

When setting up an SSO solution, use a secure connection (HTTPS) to encrypt communication between the identity provider and the service provider.


Configure Single Logout

Single logout (SLO) is a feature of SSO that allows users to log out of all applications with a single click. When configuring your SSO solution, enable single logout to provide your users with a better experience.

In addition, there are a few other things that you should keep in mind when configuring your SSO solution, such as:

  • The authentication methods that you will use
  • The security policies that you will implement
  • The user experience that you want to provide


Test Your SSO Solution

Once you have your SSO solution configured, be sure to test it thoroughly before rolling it out to your users. This will ensure that there are no problems with the implementation and that your users have a positive experience.

When you’re ready to implement SSO, keep these things in mind to ensure a smooth and successful deployment. Remember that the specific steps of implementing an SSO solution will differ depending on what exact SSO solution you will use. So, be sure to consult the documentation of your chosen SSO solution for specific instructions.
