Emerging passwordless authentication methods
Benefits of passwordless authentication technologies
In recent years, industry-leading companies have gravitated toward passwordless authentication. This shift marks a pivotal evolution in securing digital identities. Emerging technologies such as biometric verification, hardware tokens, and single-use codes are gaining traction since these methods enhance security while improving the user’s experience. As more organizations pivot to passwordless authentication, they realize the benefits and potential for the future of digital security. Businesses that adopt these more innovative approaches are better positioned to enhance cybersecurity and combat threats.
There are significant advantages for companies and users when they move beyond traditional passwords and toward these and other digital security authentication technologies. First and foremost, they offer enhanced security. Traditional passwords can be weak or reused and compromised in data breaches. Alternatively, biometrics such as fingerprints and facial recognition make it difficult for attackers to impersonate users.
- Hardware security tokens. These devices generate unique authentication codes when connected to a computer or tapped on a phone, providing a physical layer of security.
- One-time passwords (OTPs). OTPs are short-lived codes sent via SMS, email, or authentication apps. Users enter the OTP for secure, one-time access to an account.
- Biometric authentication. This method uses unique biological features to authenticate users, including facial recognition, fingerprints, or voice recognition. This technology is commonly used in smartphones, laptops, and enterprise systems.
- Push notifications. Users receive a push notification on their mobile devices when they attempt to log in. They can confirm or deny the login attempt without a password, ensuring a secure login experience.
- QR code authentication. Users scan a QR code with their mobile device to log in to an application, creating a secure link between the device and the service.
Passwordless authentication minimizes human error as well. Users often create weak passwords and reuse them across multiple accounts. Moving to biometrics and other passwordless methods reduces the reliance on error-prone human actions. Since passwordless authentication eliminates the need to remember and manage multiple passwords, the user experience is improved, and login processes are smoother and more convenient.
To overcome these challenges, it’s critical for organizations to invest in infrastructure to manage authentication, such as securing hardware tokens or biometric data storage, while maintaining privacy and regulatory compliance. It’s important for companies to implement new technologies gradually, starting with smaller teams or use cases, offer extensive user training and support, and ensure interoperability with existing systems. Businesses can also work with experienced vendors who provide comprehensive passwordless solutions and develop strong policies to protect data.
Companies effectively implementing passwordless authentication
While the benefits are significant, companies face inherent challenges when implementing these solutions. Legacy systems may not support modern authentication methods requiring costly upgrades or replacements. Also, user adoption of new technologies can be slow, especially if employees or customers resist change or find the latest methods challenging to understand. In 2023, Microsoft reported that only 28 percent of its users had enabled multifactor authentication. Moreover, ensuring compatibility across devices and platforms can be complex, as some devices may not support specific passwordless technologies.
Several forms of passwordless authentication are utilized widely today. The most common include:

Challenges in implementing passwordless solutions
Traditional password-based authentication presents several weaknesses for companies, employees, and customers. These systems are vulnerable to cyberattacks, putting sensitive data and information at risk. In addition to security issues, password-based systems are costly to maintain and create user-experience challenges, including remembering multiple, often complex passwords. Examples of high-profile security breaches at companies like MGM Resorts, Dish Network, and Go Daddy underscore the need for better, more secure solutions.
The momentum behind passwordless authentication shows no signs of slowing, and its evolution will reshape the future of digital security. Looking ahead, new and emerging technologies such as behavior biometrics, which analyzes patterns in how users interact with their devices (e.g., typing speed, swiping gestures), will redefine how people log into websites, apps, and other systems. Additionally, innovations such as decentralized identity systems, zero-trust frameworks, and adaptive authentication are critical for creating more secure and user-friendly experiences. Companies that pave the way to a passwordless future will help shape industry standards for robust, seamless, and cost-effective security practices and establish a foundation for a digital ecosystem that prioritizes convenience and trust.
Companies and their IT teams also save time and money when moving away from traditional passwords. Managing password resets, breaches, and user support around passwords consumes valuable resources. Shifting away from passwords reduces IT costs and the burden on IT teams.
Organizations are successfully implementing these innovative and secure authentication systems. Microsoft adopted passwordless authentication through Windows Hello, which allows users to log in using biometric features like facial recognition or fingerprint scanning. According to Microsoft, 99.9 percent of its compromised accounts do not have multifactor authentication enabled. Google offers hardware-based two-factor authentication that users can employ alongside their accounts as well as through secure keys and the FIDO2 standard. Duo Security (acquired by Cisco) uses two-factor authentication, a method that combines push notifications, SMS codes, and biometric verification. Okta leverages passwordless login solutions, including biometrics, adaptive authentication, and multi-factor approaches.
