Many organizations today are quickly moving towards efficient and secure authentication methods for their day-to-day operations. The debate is usually between single sign-on (SSO) and multi-factor authentication (MFA) – two of the most popular forms of authentication used for technology-driven operations. In this article, we will be examining the differences between SSO and MFA in detail, including how they are used to secure data in various companies, their respective advantages and disadvantages, as well as the best authentication technology for businesses to adopt. From understanding the basics of authentication to learning the differences between SSO and MFA, this article provides a comprehensive overview of single sign-on vs multi-factor authentication methods.
1. What is Single Sign On (SSO) and Multi-Factor Authentication (MFA)?
Single Sign On (SSO) is an authentication process that enables users to access multiple applications with one set of login credentials. It eliminates the need for users to remember multiple usernames and passwords, reducing the chances of making errors. Instead, a single identity is used to access a range of services, resulting in fewer login steps and fewer passwords to remember.
Multi-factor authentication (MFA) provides an additional layer of security beyond a username and password when accessing an application. It requires users to provide additional credentials such as a unique code that’s sent to their mobile device, biometric factors, or answers to security questions. MFA is an effective way to add extra protection to your online accounts, making them much harder for hackers to breach.
2. Benefits of Single Sign-On vs Multi-Factor Authentication
Single Sign On (SSO) is a simple way to provide secure access to multiple services with one username and password. SSO offers a number of advantages over multiple-factor authentication (MFA) such as enhanced convenience, greater access control, and a reduction in IT costs.
Here are the primary benefits of SSO compared to MFA:
- Enhanced convenience: SSO reduces user frustration by eliminating additional sign-in requirements, ensuring that users can quickly access multiple web applications with a single set of credentials.
- Greater access control: With SSO, users are granted access to multiple service providers with just a single account. This helps strengthen security and prevent unwanted access to unauthorized users.
- Reduced IT costs: SSO substantially reduces IT costs associated with password updates and authentication. It also helps minimize user support costs related to account creation and maintenance.
Overall, SSO is a more cost-effective and efficient solution for user authentication than MFA. It provides a secure way to access multiple services with just one sign-in while also saving time and money.
3. Potential Drawbacks of SSO and MFA
Increased Security Issues
Despite uniquely enhanced security features such as MFA (Multi-Factor Authentication), SSO (Single Sign-On) solutions can still be vulnerable to hackers. Cyber-attacks are no longer limited to existing authentication methods, such as usernames and passwords, but now are also targeting other layers of authentication. Therefore, having too many restrictions in place for SSO and MFA can potentially lead to more security issues.
High Login Friction
Although Single Sign-On is meant to reduce the number of steps users need to take in order to access their accounts, the implementation of such a system can still be quite cumbersome. This can be especially frustrating if users are required to re-authenticate themselves multiple times for the same set of resources, leading to an increase in login friction. For example, they may have to provide multiple forms of authentication, such as their SSO credentials, MFA authentication, and a secondary set of passwords. This could lead to users feeling overwhelmed and potentially deter them from using the service.
4. Making the Right Choice: SSO vs MFA
When it comes to online security, organizations often have to make a decision between two popular options: Single Sign-On (SSO) or Multi-Factor Authentication (MFA). Here are the key differences between the two to help you make the right choice.
- SSO is a centralized authentication service that eliminates the need for users to remember multiple usernames and passwords when logging into multiple accounts. With SSO, they can access all their accounts with just one set of credentials.
- MFA requires users to provide two or more independent authentication factors in order to gain access. These can include something you know (like a password), something you have (like a hardware token or mobile phone) and something you are (like biometric information).
The main benefit of SSO is its convenience – it makes it easier for users to access their accounts. On the other hand, MFA is a more secure option since it requires multiple levels of authentication. Organizations that need to protect confidential data or regulate access should opt for MFA.
Both authentication methods can be used together or separately, depending on the security needs of the organization.
Single Sign-On (SSO) and Multi-Factor Authentication (MFA) are two methods of authentication designed to enhance security for users accessing online resources and applications. SSO allows users to log in only once to gain access to multiple applications, increasing user convenience and presenting a security risk if the single authentication method is compromised.
On the other hand, MFA requires users to provide multiple forms of verification, such as passwords, fingerprints, retina scans, or one-time codes, adding layers of security to the authentication process. Companies like Progress Software and Sunvera Software offer robust protection through complete MFA solutions, ensuring that only authorized users can access sensitive information. While SSO may be more convenient for users, MFA provides improved security against threats like social engineering attacks or brute force attacks.
By implementing a combination of SSO and MFA, organizations can strike a balance between user convenience and security requirements, effectively protecting their digital assets from malicious actors and potential security breaches.

| Primary Advantage | Enhanced convenience | Increased security |
| Access Control | Users can access multiple services with a single account | Requires multiple levels of authentication |
| IT Costs | Reduces IT costs associated with authentication | May increase IT costs due to additional security measures |
| User Experience | Minimizes steps for users to access accounts | This can lead to increased login friction |
| Security | Less secure compared to MFA | More secure due to multiple authentication factors |
Q&A
Q: What is the difference between Single Sign On (SSO) and Multi Factor Authentication (MFA)?
A: Single Sign On (SSO) lets you access multiple accounts with a single account. Multi Factor Authentication (MFA) requires you to provide additional forms of identification to securely access an account. In other words, SSO simplifies authentication by using one set of credentials, while MFA is more secure because you must prove who you are with additional authentication methods.
Q: What are the advantages of Multi-Factor Authentication over Single Sign On?
A: MFA provides an extra layer of protection against unauthorized access by adding additional factors such as biometric scans, one-time passwords, or security tokens. This enhances user security and reduces the risk of phishing attacks compared to relying solely on a single login.
Q: How does Multi-Factor Authentication impact user experience?
A: While MFA may add an additional step to the login process, it ultimately improves user security without causing too much friction for the user. With the rise of authentication methodologies like push notifications and fingerprint scans, MFA offers a streamlined experience for users while maintaining a high level of security.
Q: What are some common types of additional factors used in Multi-Factor Authentication?
A: Some common types of additional factors used in MFA include biometric authentication (such as fingerprint or facial scans), one-time passwords generated by an Authenticator app, and physical tokens like security keys.
Q: How does Multi-Factor Authentication help enterprises balance between convenience and security?
A: By adding an extra layer of protection to the authentication process, MFA helps enterprises strike a delicate balance between providing users with a seamless login experience and ensuring robust defense against cyber threats. This helps organizations meet regulatory requirements and protect sensitive systems and data.
