How does Passwordless Work?

Introduction: Traditional Password-Based Authentication vs. Passwordless Authentication

Traditional password-based authentication has long been the standard method for securing online accounts. However, with the rise of more sophisticated cyber threats, the need for a more secure and convenient alternative has emerged. Passwordless authentication offers a solution that mitigates many of the risks associated with traditional password-based systems. In this article, we will explore the key differences between these two authentication methods, how passwordless authentication works, and the benefits it offers for both users and organizations.

Understanding Traditional Password-Based Authentication

Traditional password-based authentication relies on a user providing their username and password as a means of verifying their identity when accessing an online platform or application. This method is widely used due to its simplicity and familiarity. However, it has several inherent weaknesses, such as susceptibility to password theft, phishing, and brute force attacks.

Exploring Passwordless Authentication Methods

Passwordless authentication offers an alternative to traditional passwords by utilizing various methods to confirm a user’s identity without the need for a password. These methods include:

  1. Biometric authentication: Verification through unique physical characteristics, such as fingerprint scans, facial recognition, or iris scans.
  2. FIDO2 security keys: Hardware devices used to authenticate a user’s identity on websites and apps securely.
  3. Time-based one-time passwords (TOTPs): Temporary codes generated on a user’s device, which expire after a short duration.

The Passwordless Authentication Process

To access a website or app using passwordless authentication, users must first verify their identity through one of the methods mentioned above. For instance, biometric authentication requires scanning a fingerprint or face, while using a FIDO2 security key involves connecting the key to the user’s device. In the case of TOTPs, users must input the generated code displayed on their device. Upon successful verification, users gain access to the desired platform or application.

Advantages of Passwordless Authentication

Adopting passwordless authentication presents numerous benefits for users and organizations alike, such as:

  1. Enhanced security: Passwordless authentication reduces the risk of cyberattacks, as it is significantly more challenging for hackers to compromise biometric data or physical security keys compared to stealing passwords.
  2. Greater convenience: Users no longer need to remember or input passwords, streamlining the login process and reducing password fatigue.
  3. Reduced IT costs: Organizations can save on IT expenses by minimizing the number of password resets required, as users are less likely to forget their authentication method or become locked out of their accounts.


As cyber threats continue to evolve, it is crucial for organizations to adopt more secure and user-friendly authentication methods. Passwordless authentication offers a reliable and convenient alternative to traditional password-based systems, providing increased security, improved user experience, and reduced IT costs. Embracing passwordless authentication can help organizations stay ahead of the curve in the ongoing battle against cybercrime.
