The future of authentication is passwordless.

In a world where we have countless online accounts and digital platforms to navigate, passwords have become a necessary evil. We're all too familiar with the frustrations of forgotten passwords, security breaches, and the constant pressure to create complex combinations of letters, numbers, and symbols.

But what if there is a future where passwords are no longer required? A future where authentication is seamless, effortless, and secure. Welcome to the era of passwordless authentication. This innovative digital security approach is revolutionising how we access our online accounts, making our lives easier and safer.

In this article, we'll explore the benefits of passwordless authentication, the technology behind it, and why it's poised to become the new standard in online security. Say goodbye to password hassles and join us as we dive into the exciting world of passwordless authentication.

The problems with traditional passwords

For decades, traditional passwords have been the go-to method for securing our online accounts. However, they come with a set of inherent problems that have become increasingly apparent in today's digital landscape. Firstly, passwords are often difficult to remember, leading to frequent instances of forgotten passwords and the need for password reset procedures. This wastes time causes user frustration and burdens customer support teams unnecessarily.

Furthermore, the practice of using the same password across multiple accounts is alarmingly common. This poses a significant security risk, as a breach in one account can potentially lead to unauthorised access to multiple accounts. Additionally, the requirement for complex passwords with a combination of uppercase letters, lowercase letters, numbers, and symbols often leads to users resorting to predictable patterns or writing passwords down, further compromising security.

Lastly, passwords are susceptible to hacking attempts. Cybercriminals employ various methods, such as brute-force attacks, phishing, and password-cracking software, to gain unauthorised access to accounts. With the increasing sophistication of these attacks, relying solely on passwords for authentication is no longer a reliable or secure option.

What is passwordless authentication?

Passwordless authentication is an authentication method in which a user can log in without entering (and having to remember) a password or any other knowledge-based secret. In most common implementations users are asked to enter their public identifier (username, phone number, email address etc.) and then complete the authentication process by providing a secure proof of identity through a registered device or token.

Passwordless authentication methods typically rely on public-key cryptography infrastructure where the public key is provided during registration to the authenticating service (remote server, application or website) while the private key is kept on a user’s device (PC, smartphone or an external security token) and can be accessed only by providing a biometric signature or another authentication factor which is not knowledge-based. These factors classically fall into two categories:

  • Ownership factors (“something the user has”) such as a mobile phone, OTP token, smart card or hardware token.
  • Inherence factors (“something the user is”) like fingerprints, retinal scans, face or voice recognition and other biometric identifiers.

Some designs might also accept a combination of other factors such as geolocation, network address, behavioural patterns and gestures, as long as no memorised passwords are involved.

Passwordless authentication is sometimes confused with multi-factor authentication (MFA) since both use a wide variety of authentication factors, but while MFA is often used as an added layer of security on top of password-based authentication, passwordless authentication does not require a memorised secret and usually uses just one highly secure factor to authenticate identity, making it faster and simpler for users. "Passwordless MFA" is the term used when both approaches are employed, and the authentication flow is both passwordless and uses multiple factors, providing the highest security level when implemented correctly.

The shift towards passwordless authentication brings a plethora of benefits for both users and businesses. Let's explore some of the key advantages:

Enhanced security

One of the primary advantages of passwordless authentication is enhanced security. As mentioned earlier, passwords are susceptible to various hacking techniques. The risk of unauthorised access is significantly reduced by eliminating passwords and adopting more secure authentication methods, such as biometric data or hardware tokens. Biometric data, such as fingerprints or facial recognition, is unique to each individual, making it extremely difficult to forge or replicate. Additionally, hardware tokens provide an added layer of security as they are physical devices that are not easily compromised.

Improved user experience

Passwordless authentication offers a more streamlined and user-friendly experience. Users no longer need to remember and enter complex passwords, increasing convenience and reducing the likelihood of forgotten passwords. This eliminates the need for time-consuming password reset procedures and reduces the burden on customer support teams. The authentication process becomes faster and more seamless, enhancing the overall user experience.

Reduced risk of credential stuffing attacks

Credential stuffing attacks occur when hackers use stolen usernames and passwords from one website to gain unauthorised access to other websites where users have reused the same credentials. Passwordless authentication significantly reduces the risk of credential stuffing attacks, as there are no passwords to steal and reuse. Each authentication method used in passwordless authentication is unique to the user, making it much more difficult for hackers to gain unauthorised access to multiple accounts.

Scalability and compatibility

Passwordless authentication is highly scalable and compatible with various platforms and devices. Passwordless authentication methods can be seamlessly integrated if users are accessing their accounts from a computer, smartphone, or wearable device. This flexibility allows for a consistent and secure authentication experience across different devices and platforms, catering to the needs of today's multi-device and interconnected world.

How does passwordless authentication work?

Now that we understand the benefits of passwordless authentication let's delve into how it works. The exact implementation of passwordless authentication can vary depending on the specific method being used, but the general principles remain the same.

The process typically involves three main steps:

  1. User enrollment: During the initial setup, users will need to register their preferred authentication method. This could involve capturing and storing biometric data, such as fingerprints or facial recognition scans, or pairing a hardware token with their account. This step ensures the user's unique identifier is securely stored and associated with their account.
  2. Authentication request: When a user attempts to access their account, they will trigger an authentication request. This request can be initiated by entering an email address or username associated with the account or using a mobile app or hardware token. The user's unique identifier is then sent to the authentication server for verification.
  3. Verification and access grant: The authentication server receives the user's unique identifier and matches it against the stored identifier associated with the account. If the identifiers match, the user is granted access to their account. This process can involve additional security checks, such as biometric verification or physical interaction with the hardware token to ensure maximum security.

Common methods of passwordless authentication

There are several methods of passwordless authentication that are commonly used today. Let's explore some of the most popular ones:


A passkey is a digital credential, tied to a user account and a website or application. They are often stored by the operating system or web browser and synchronised between devices from the same ecosystem, however they can also be confined to a single device such as a physical security key. They are normally secured using possession (of the device or security key), and often utilise biometrics as an additional security factor, neither of which requires the user to memorise a password.

Biometric authentication

Biometric authentication utilises unique physical or behavioural characteristics to verify a user's identity. This can involve scanning fingerprints, facial recognition, voice recognition, or even iris scans. Biometric data is highly secure and difficult to replicate, making it an effective and convenient method of passwordless authentication. Many modern smartphones and laptops now come equipped with biometric sensors, making them easily accessible for users.

Mobile app-based authentication

Mobile app-based authentication involves using a dedicated mobile app to verify a user's identity. This method often utilises push notifications, QR codes, or one-time passwords (OTPs) sent to the user's mobile device. The user needs to approve the authentication request on their mobile app to gain access to their account. Mobile app-based authentication is widely used by popular services like Google and Microsoft.

Hardware tokens

Hardware tokens are physical devices that generate unique authentication codes. These tokens can be in the form of USB keys, smart cards, or even wearable devices. When a user needs to authenticate themselves, they plug in the token or interact with it physically to generate a one-time code. This code is then entered into the authentication prompt to gain access to the account. Hardware tokens provide an additional layer of security as they are physical devices that cannot be easily compromised.

Email or SMS verification

Email or SMS verification is a simple and widely adopted method of passwordless authentication. When users attempt to access their accounts, a verification code (or magic link) is sent to their registered email address or mobile phone number. To gain access, the user then enters this code (or clicks on the magic link) into the authentication prompt. While this method is convenient, it is important to note that email or SMS can be vulnerable to interception or social engineering attacks. Therefore, additional security measures should be implemented to ensure the integrity of the process.

Implementing passwordless authentication in your financial services business

The financial services industry is one that can greatly benefit from the adoption of passwordless authentication. Strong authentication practices protect sensitive customer data, prevent fraud, and maintain trust.
