Top 10 Passwordless Authentication Solutions for Customers

Passwords are broken. They’re the weakest link in our digital security chain, costing businesses billions.

According to a study by Forbes Advisor, 46% of Americans have had their passwords stolen in the past year.  Traditional password-based authentication is weak and makes individuals and businesses vulnerable. But what if we didn’t have to use passwords at all?

Passwordless authentication isn’t just a technological upgrade; it’s a fundamental shift in protecting our digital identities and assets. It’s time to move beyond passwords and embrace a more secure, user-friendly approach.

What are passwordless authentication solutions for customers?

Passwordless authentication enables customers to log into services, devices, or applications without traditional passwords, often using methods like biometrics or temporary passcodes. Common examples include smartphones’ fingerprint scanners or face IDs. Besides improving user experience, passwordless authentication has increased security over passwords. Passwordless authentication stops users from sharing or reusing weak passwords.

However, it’s important to remember that passwordless authentication is not foolproof and should be fortified with additional security measures to ensure maximum protection against cyber threats.

Common Forms of Passwordless Solutions


5 Types of Passwordless Authentication Solutions for Customers

Here are five common types of passwordless authentication solutions that are changing the way we log in.

  1. Biometrics (Fingerprint, Facial Recognition): Biometric authentication uses unique physical traits like fingerprints or facial features to verify users. Advancements in AI are making these systems a more reliable and secure way to log in.
  2. Magic Links (One-Time Codes): Magic links are temporary codes sent via email or SMS that allow users to log in without passwords.
  3. Authenticator Apps: Authenticator apps generate time-based codes that users enter along with their credentials for added security.
  4. Hardware Tokens: These small physical devices generate one-time codes that users enter for authentication, adding an extra layer of security. 
  5. Passkeys: Passkeys are digital credentials tied to user accounts, offering improved phishing resistance but still vulnerable to certain attacks, highlighting the importance of robust security measures even in passwordless environments.

Benefits and Drawbacks of Passwordless Authentication Solutions for Customers


  • Reduced Phishing Risk: Passwordless authentication eliminates the primary target of phishing attacks: the password itself. Biometric factors (fingerprint, facial recognition) and possession factors (one-time codes, security keys) are significantly harder to steal or replicate remotely.
  • Enhanced Multi-Factor Authentication (MFA): Passwordless methods seamlessly integrate into MFA schemes, replacing the knowledge factor (password) with something the user is (biometric) or something the user has (OTP, security key). This significantly strengthens overall account security.
  • Reduced Account Takeover (ATO) Risk: While not eliminating ATO entirely, passwordless authentication raises the bar significantly. Attackers can no longer rely on stolen credentials alone. They would need to compromise additional factors, making attacks more complex and less likely to succeed.

Technical Challenges & Mitigations: 

  • SIM Swapping: Attackers can gain control of a user’s phone number to intercept one-time codes (OTPs). Mitigations include app-based OTP generators, push notifications, or hardware security keys.
  • Biometric Spoofing: Sophisticated attackers can bypass biometric authentication using fake fingerprints or facial replicas. Mitigations include liveness detection (checking for genuine biological traits), multi-modal biometrics (combining multiple biometric factors), and behavioral biometrics (analyzing user interaction patterns).
  • Man-in-the-Middle (MitM) Attacks: Attackers can intercept communication between the user and the authentication server to steal authentication tokens or session cookies. Mitigations include strong encryption, secure channels (HTTPS), and device binding (linking authentication sessions to specific devices).
  • Malware and Phishing: Malware can steal biometric data or OTPs stored on a device, while phishing attacks can trick users into revealing sensitive information. Mitigations include:
    • Educating users about safe practices.
    • Using anti-malware software.
    • Employing robust authentication methods for sensitive operations.

Key Features of Passwordless Authentication Solutions for Customers

When choosing a passwordless authentication solution, prioritize the following key features:

  • Security Strength: Assess the security measures such as encryption standards, resistance to phishing attacks, and the robustness of authentication protocols. Data security posture management (DSPM) can be a valuable tool to assess and maintain the security posture of your authentication solution.
  • User Adoption: Prioritize intuitive and familiar solutions that don’t require technical expertise. A complex authentication system may lead to customer churn. 
  • Scalability: Always be prepared for growth. You want to choose a solution that can scale when business comes in. Ensure the solution can accommodate increasing numbers of users and transactions without compromising performance or security.
  • Compatibility: Adopting a passwordless solution incompatible with your existing systems is cost-prohibitive. Look for solutions that offer robust APIs, SDKs, and support for industry-standard protocols.
  • Regulatory Compliance: Consider regulatory requirements and compliance standards relevant to your industry and geographic location. Your compliance with GDPR, HIPAA, or PCI DSS relies on any third-party solutions you integrate into your systems. A strong IT security policy can help ensure compliance and mitigate risks associated with passwordless authentication.
  • Reliability and Uptime: Choose solutions with high availability and resilience to ensure uninterrupted customer access. Look for providers with a proven track record of reliability and uptime backed by robust infrastructure and disaster recovery capabilities.
  • Cost and Value: Consider upfront costs, ongoing maintenance fees, and potential savings from reduced support overhead and security incidents.
