Passwordless Authentication?

It’s no secret — passwords can be a real headache, both for the people who use them and the people who manage them. Over time, we’ve created hundreds of passwords, it’s easy to lose track of them, and they’re easily compromised. Fortunately, passwordless authentication is becoming a feasible reality for many businesses. Duo can help you get there.

What is Passwordless Authentication?

Passwordless authentication (or “modern authentication,” as it is known by some) is the term used to describe a group of identity verification methods that don’t rely on passwords. Biometrics, security keys, and specialized mobile applications are all considered “passwordless” or “modern” authentication methods. Because it addresses the ever-pervasive problem of credential theft, some industry experts have even characterized passwordless as the future of authentication.

Passwordless provides secure access for every enterprise use case (hybrid, cloud, on-premises and legacy apps). Through technology partnerships, Duo is innovating toward a true passwordless future that balances usability with stronger authentication. Passwordless gives users a frictionless login experience, while reducing administrative burden and overall security risks for the enterprise.

Why Passwordless Matters

Passwordless authentication isn’t just a nice-to-have — it can actually improve an organization’s security posture and reduce costs associated with password management. Passwords create higher friction for users, slow down business productivity, and are inherently a weak form of user authentication.

Costly and Burdensome to Manage

  • 20-50% of all IT help desk tickets each year are for password resets (Security Boulevard)
  • Each year, U.S.-based enterprises allocate over $1 million to password-related support costs (Forrester

Poor User Experiences

Easily Compromised

  • Passwords that are easily detectable or reused often are vulnerable to phishing attacks. Over 80% of hacking breaches involve brute force or the use of lost or stolen credentials. (Verizon DBIR)

How Passwordless Works

Passwordless authentication ideally involves less user interaction during the login process than traditional forms of authentication. It uses public key cryptography, which authenticates the user with a pair of cryptographic keys — a private key that’s a secret, and a public key that isn’t — and it comes with a lexicon of new (or relatively new) acronyms and standards like FIDO2 standard (FIDO stands for Fast IDentity Online and FIDO2 is just an umbrella term for the combination of WebAuthn and Client to Authenticator Protocol (CTAP)). 

Implementing passwordless is no small task, especially when you’re dealing with large user populations, a substantial number of apps, hybrid infrastructures and complex login flows. Achieving a completely passwordless environment is a journey that involves a phased approach as technology continues to evolve and user adoption increases. Although complete elimination of passwords is still far off, reducing reliance on them is already feasible by implementing MFA, establishing trust in devices, leveraging SSO and implementing adaptive access policies

Why Implement Passwordless?

Passwordless authentication provides a single, strong assurance of users' identities to achieve user trust. For enterprises, this means:

Group 19

Better User Experience

A reduction in user frustration and an increase in user productivity.

Group 13

Reduced IT Time and Costs

A reduction of the administrative burden of password-related help desk tickets and password resets.

Group 4

Stronger Security Posture

The elimination of threats and vulnerabilities related to passwords (phishing, stolen or weak passwords, password reuse, brute-force attacks, etc.).

Is Passwordless A Good Choice For Me?

If your business has a goal of reducing the security risk associated with passwords, the answer is almost certainly “yes.” Identity is becoming the new perimeter, and to secure it, companies must put access controls around both users and their devices — also known as the “workforce.”

To address this new reality, many organizations are adopting a zero-trust security approach, under which trust is verified at each access attempt. The best security should be invisible and have minimal impact on the productivity of users. Passwordless authentication is a key part of verifying user trust, in a more user-friendly, simplified and secure way. 

However, there are a few factors that will determine the level of effort involved in implementing passwordless. If you have a complex hybrid environment, it’s going to be more difficult to transition to passwordless. 

We recommend having a few technical experts assigned specifically to your passwordless project, so that you can address any issues as they arise. When done correctly, however, a passwordless approach significantly minimizes the likelihood of a breach due to stolen credentials.

With security education and multi-factor authentication (MFA), breaches due to stolen passwords can be prevented 99.9% of the time.

The Solution: A Journey to Passwordless

Pairing passwordless technology with strong MFA is a practical way to provide the broadest security coverage today. With MFA in place, you can reduce your reliance on passwords and modify password policies to require less frequent resets, alleviating help desk burden and reducing user frustration. We recommend taking a phased approach to securing access for the workforce, with each step taking you closer to a fully passwordless future:

Identify passwordless use cases and enable strong authentication.

Begin to reduce your reliance on passwords and lower the risk of credential theft by selecting specific enterprise use cases for a passwordless approach.

Streamline and consolidate authentication workflows.

Reduce passwords by using single sign-on (SSO) for SAML-based Cloud applications. For on-premise services, integrate application workflows using access and authentication proxies.

Increase trust in authentication.

Apply adaptive access policies based on the context of the user, device, location, behavior, and more, to ensure the authentication can be trusted.

Provide a passwordless experience.

Enable users to log in using a single biometric authenticator (or security key) to access applications at the point of federation.

Optimize your passwordless toolset.

The final step in the journey is integrating the technology and moving towards continuous improvement. True passwordless will eliminate reliance on passwords for any login workflow, either behind the scenes or throughout your users’ experiences.

How Duo Supports Your Passwordless Journey

Duo creates consolidated solutions that balance security with usability, providing strong MFA, single-sign on, adaptive access policies and establishing device trust for hybrid environments. The building blocks to support a passwordless login experience exist today for access to cloud based applications. Our goal is to support organizations as they move to a passwordless future through the following:

1. Duo MFA

Identify passwordless use cases and enable strong authentication.

With MFA enabled for all applications, users’ credentials are protected by a strong security layer that thwarts account takeover. Once MFA is in place, password policies can be configured to require less frequent resets, getting you one step closer to a password-free user experience.

Duo MFA is available in all Duo editions.

2. SSO and the Duo Access Gateway

Streamline and consolidate authentication workflows.

Leveraging federated logins protected with MFA is an excellent step on the road to a passwordless user experience for your workforce. Use Duo to integrate an existing single-sign-on (SSO) platform, or take advantage of its alternative SSO options for SAML based applications. 

Duo SSO and the Duo Access Gateway are available in all Duo editions.

3. Access Policies and Device Trust

Increase trust in authentication.

Configuring access policies to evaluate contextual signals around each access attempt makes anomalous user behavior obvious and easy to detect. In turn, it’s easier to verify trust in the devices authorized for access, and ensure those devices don’t introduce any level of risk or compromise to an environment.

Access Policies and Device Trust are available in Duo’s Access and Beyond editions.

4. WebAuthn MFA and Agnostic Integrations

Provide a passwordless experience.

Duo supports the use of open standards, such as WebAuthn, as MFA methods for SAML applications, allowing users to authenticate without the use of a password. With this functionality, organizations can establish a passwordless login workflow for cloud applications, without ripping and replacing existing infrastructures.

WebAuthn and Agnostic Integrations are available in all Duo editions.

5. Building Toward A Fully Passwordless Product

Optimize your passwordless toolset.

While federation provides a starting point, enterprise companies are filled with complex use cases, including OS login and protecting legacy applications.  

There is work to be done to provide passwordless homogeneously throughout an environment and organizations will move iteratively towards a true passwordless future, tackling one use case at a time.  

Duo is investing and building tools that will provide the ability to scale a passwordless experience throughout a hybrid environment. Duo is working with industry and technology partners to create a comprehensive ecosystem that can support true passwordless across every enterprise use case.
