What is SSO? Know about Single Sign On and How to Use it

What is Single Sign-On (SSO)

Single Sign-On SSO Introduction

Since you are on this post, it is safe to assume that you want to know what is SSO. Well, SSO stands for single sign on. It is an authentication system that allows users to sign in to various independent software using a single ID.

With a true SSO, you can sign in once and access services without having to go through the authentication process again. An easy version of single sign on can be achieved over IP networks using cookies. However, it is only possible if the sites have a common DNS main domain.

To learn more about “what is single sign on SSO,” you should read through this post. We have explained all the important things related to single sign authentication in the lines below.

What is Single Sign-On?

So what is single sign on? Many of you are confused about what single sign on means, so let’s clarify the answer once and for all.

SSO id meaning is related to an authentication system that allows users to use a single set of login credentials – password and username to sign into multiple software. It is widely used by businesses and enterprises. However, it can also come in handy for some individuals.

If you ask us which of the following is an advantage of using SSO, we would say that it makes the management of multiple login credentials easy.

Now that you know SSO ka full form and the meaning of single sign on, we can get deeper into the topic.

How does Single Sign-On work?

A common question asked is “what is SSO in terms of cloud service security?” Well, SSO authentication is a federated identity management arrangement. It is also known as identity federation.

An Open authorization (OAuth) system enables a user’s login credentials to be used by third-party services without revealing the user’s account information.

OAuth serves as an intermediary on behalf of the user by permitting specific account details to be shared. When a user tries to log into the software, a request is sent by the service provider for authentication. The login request is verified by the service provider, after which the user is allowed to sign in.

In the case of single sign on authentication, an agent module on the software service retrieves the specific account information for an individual user from a dedicated single sign on the server. At the same time, it also verifies the user against a user repository – for example, the Lightweight Directory Access Protocol directory.

Once the user is authenticated, the person can sign into all the applications. The user also has the right to remove future password requests for individual software during the same session. 

In short, giving a username in access control is called single sign-on. After discussing SSO full form and SSO meaning, let’s move on to greater details.

More About Single Sign-On

We have already discussed what is SSO in terms of cloud security mean. Now let’s talk about what is SSO login.

You need to understand that single sign authentication works based on a trust relationship between a service provider and an identity provider. It works based on a certificate that is exchanged between the two mentioned parties. This certificate is used to sign identity details that are being exchanged between the service provider and the identity provider coming from a reliable source.

In the case of SSO authentication, identity information takes the form of tokens, containing identifying bits of data about the end user. For example, the user’s SSO password or username.

To login flow looks somewhat like this:

  • A user browses the website or the application they want to access.
  • A token is sent by the service provider which contains information about the user such as their email ID, to the SSO login system. This is sent as a part of a single sign on authentication request.
  • The identity provider will now check if the user is already authenticated, in which case, the user will be granted access to the application.
  • In case, the user is not signed in, they will be prompted by the identity provider to provide their single sign on login details. This includes an SSO id and password. In some cases, it can be some other form of authentication such as a One-Time password.
  • After the single sign-on google credentials are validated by the identity provider, it will send a token back to the service provider to confirm the authentication.
  • The token sent by the identity provider will pass through the user’s browser to the service provider.
  • The token for login SSO received by the service provider is authenticated based upon a trust relationship between the service provider and the identity provider.
  • Now the user is permitted to access the service provider.

If you try to access a different application or website, it would have to have a similar trust relationship configured with the single sign-on methods, followed by the same steps as discussed above.

You can also receive login credential received by phone calling. By now you should know the SSO full form and meaning of single sign on. In the next few sections, we will learn more single sign-on example, which will help you to understand SSO meaning further.

To figure out what is SSO, you should check out a single sign-on demo online. For this, you need to search for tutorials on the SSO portal.

What is an SSO token?

After discussing what is SSO login, now it’s time to learn about the SSO token. To put it in simple words, an SSO token is a collection of information or data that is transferred from one system to another during the SSO integration process. It can be a user’s email ID and data about the system that is sending the token.

Tokens need to be signed so they can be verified by the token receiver. This is to prove that the token is coming from a reliable source. The certificate used for the digital signature is exchanged during the configuration process.

Now that you know the single sign on meaning, the concept of SSO tokens should be easier for you to understand. Knowing what is single sign on SSO helps you to understand other things that are related to it.

Is SSO secure?

We have already answered the question of what is single sign on. The next common question is if SSO is secure. Well, it’s not possible to answer this question with a simple yes or no.

SSO. login can help improve security in many ways. It can simplify passwords and usernames for both administrators and users. It allows users to use a single set of usernames and passwords for all the applications. This saves time and lets users access their software quickly.

SSO id sign in also reduces the time needed by the help desk to retrieve lost passwords. It allows administrators to have full control over the system. They can also relinquish login benefits across the board when a user exits the organization.

However, the SSO token has certain drawbacks that cannot be overlooked. For example, you may have some software that you want to secure a bit more. In this case, you will need an SSO solution that includes an additional authentication factor. Or it will prevent users from accessing the software unless they are connected to a secure network.

After reading the above paragraphs, we have got the answer to the question of what is SSO authentication. Along with that we also learned a few important things related to it.

How is SSO implemented?

In this section, we will tell you how single sign on login is implemented in organizations. This will help you to understand the SSO login meaning further.

The basics of implementation will vary depending on the SSO database you are using. Regardless of the steps, you should have a set goal or objective for your implementation. Before you start, you need to answer a few questions.

  • What type of users are serving and what are the different requirements?
  • Is API access needed?
  • What are the systems that need to be integrated?
  • What are the important features needed to ensure that only trusted users are signing in?
  • Is this solution right for your company? Will it meet the requirements of your company?
  • Do you need a cloud-based solution or an On-Premise solution?

SSO On First Login

For single sign-on Auth0, the Central Service is the Auth0 Authorisation Server. With that said, let’s take a look at the steps when a user logs into the SSO portal for the first time.

  • Your application will take the user to the main login page.
  • Auth0 will check for an SSO cookie.
  • If there’s no cookie present, the user will be asked to sign in using a configured connection.
  • After signing in, Auth0 will set an SSO cookie. On the other hand, the user will be redirected to the application and sent a token containing the identity data.

So now you have an idea of what the SSO portal looks like when you log in for the first time. We have also covered the SSO full form in one of the above sections. If you read the post mindfully, you will understand the system better.

SSO On Subsequent Logins

Now that you know how SSO id looks when logging in for the first time, let’s move on to further details. In this section, we will give you an example of how SSO jsw login looks when a user returns to your application or website.

  • The user will be redirected to the login page by the application.
  • Auth0 will check if there’s an existing cookie.
  • Since the user is a returning one, a cookie should be present.
  • The system will update the cookie if necessary. 
  • Once that is done, the user will be redirected to the application and sent a token containing the identification data. The user will no longer be shown the login page.

Knowing the SSO meaning will help you to understand how SSO login works and how everything is connected.

Check the User’s SSO Status

In case, you didn’t know you can check the SSO gem login status using a particular application. All you have to do is use the checkSession method of auth0.js. The user will be authenticated within an iFrame by SDK.

It will indicate if the authentication is successful or not. It will also let you know if the user has an active SSO cookie or not.

Along with the full form of SSO, we have discussed several important things related to how SSO work

What are the advantages of SSO?

There’s no doubt that SSO is a time-saving system. With SSO, you don’t need to sign into multiple applications every day. Instead, it permits signing in only once for all the applications. This automatically reduces the number of usernames and passwords that users need to remember. It wouldn’t be wrong to say that SSO makes an organization more secure.

The main benefits of SSO are:

  • Reduces the number of passwords

Managing a lot of passwords is difficult. You also can’t use the same password with little variation. This is because if one application gets hacked, the hacker will easily hack the other applications. This is where SSO comes in handy. It allows you to eliminate the need to have multiple short passwords. One strong password is enough to log you into multiple applications. Also, a complex password is not easy to crack.

  • Helps fix unsafe password storage habits

SSO can reduce the need for password managers, passwords written on sticky notes, or passwords stored in spreadsheets. It makes password management easier and quicker. It will make sure that your passwords are safe and don’t get revealed to the wrong people.

  • Keeps you safe from hackers

SSO is known to simplify the management of user accounts. With the help of this system, administrators gain more centralized control over authentication requirements. When a user exits an organization, administrators can remove permissions for the user account in just a few simple steps.

  • Help simplify regulatory compliance

Another good thing about SSO is that it makes it easier to meet regulatory requirements for the protection of data access control and personal identity information. It also comes in handy for specific requirements and regulations such as HIPAA. 

Risk Of SSO

Despite all the good things, SSO is not completely free of faults. There are a few things that need to be taken into account before implementing this system in your organization.

Since SSO uses the same login credentials for all applications, it poses a huge threat to users. If one application gets hacked, the others will get hacked too.

Even though it requires users to create long and complex passwords, it is not completely safe to use. If you are using log in SSO, you need to be careful with the encryption part.

The best way to use SSO is with multi-factor authentication. It requires users to provide at least one authentication factor along with the password. This could include a fingerprint, an ID card, or a mobile phone. These additional credentials cannot be stolen by hackers.

By now you should know what single sign on means or SSO full form in computer. It is a useful system, but risky at the same time.
