The Next Measure toward Cybersecurity

Key takeaways

• Passwords are no longer effective against hackers because of their enhanced potential in recent years.
• Credential stuffing is a cyberattack in which user accounts are accessed without authorization by using lists of username, email addresses, and accompanying passwords taken from users’ accounts.
• When compared to the penalties and damages brought on by a data breach, the expense of deploying passwordless is negligible.

Passwords are no longer effective against hackers because of their enhanced potential in recent years. How many times have you created a complicated password using a mix of letters and numbers just to forget it yourself?

Studies show that weak or stolen passwords are involved in 81% of breaches. As a solution to these password breaches, passwordless authentication has been introduced. Passwordless authentication is a way of verifying a user without using any passwords. Interesting, right?

Passwordless authentication employs more secure substitutes, such as biometrics, registered devices, or one-time passwords (OTPs). This article is going to introduce you to the concept of passwordless authentication.

How Does Passwordless Authentication Work? #

In passwordless authentication, we remove the option of passwords for security (pretty obvious from the name), and instead replace it with various authentication factors that are potentially more secure. A user-provided password is compared to the database’s entries during password-based authentication.

Similar comparisons take place with password-free systems like biometrics, although in these systems, the user’s unique traits are compared rather than passwords. Comparisons may take place in various ways in other passwordless systems, like as OTPs.

For instance, a system may send an SMS or email with a one-time passcode to a user’s mobile device, who then enters it in the login box. The system then matches the passcode entered by the user to the one it had previously sent.

The same concepts that govern digital certificates apply to passwordless authentication: a cryptographic key pair with a private and a public key. Consider the public key as the padlock and the private key as the real key that unlocks it, even though they are both referred to as keys. The user’s local device houses the private key, which is only accessible with an authentication factor.

Types of Passwordless Authentication #

As discussed before, there can be various ways to achieve passwordless authentication. Here are three ways:

Biometrics #

A person may be uniquely identified by physical characteristics like fingerprints or retinal scans as well as behavioral characteristics like typing and touch screen dynamics. Certain physical attributes can now be faked thanks to contemporary AI, but behavioral traits are still very difficult to do so.

Aspects of possession #

Authentication by possession of an item that the user is carrying. A hardware token, an OTP sent through SMS, or a code produced by a smartphone authenticator app are a few examples.

Magic links #

When a user inputs their email address, the system automatically sends them an email. The email includes a link that, when clicked, gives the user access.

Benefits of Passwordless Authentication #

By expediting the authentication process using passwordless authentication, you may improve the user experience by eliminating the need to remember secret passwords. Here are some other benefits of passwordless authentication:

It provides better security #

By now, everyone is aware that user-controlled passwords pose a serious risk due to the ease with which users may exchange and reuse passwords. Passwordless authentication removes that risk.

It prevents password spraying #

An assault known as “password spraying” aims to get access to several accounts using a small number of widely used passwords. This can be avoided with passwordless authentication.

It prevents credential stuffing #

Credential stuffing is a cyberattack in which user accounts are accessed without authorization by using lists of username, email addresses, and accompanying passwords taken from users’ accounts. The risk of credential stuffing is reduced by eliminating user-generated passwords.

Reduces Total Cost of Ownership (TCO) #

Removing passwords will decrease support requests and enable IT to handle actual problems because passwords are costly and require regular maintenance from IT workers.

Controls phishing #

Phishing hacks are hacks that look legitimate but are actually attempts to trick users into giving over sensitive data.

In an effort to persuade the targets that the communications are genuine, spear phishing messages are customized to the targets by obtaining personal information about the victim.

It terminates brute force attack #

Brute force attacks entail making several login attempts while attempting to guess passwords using every available letter, number, and character combination. That can be stopped via passwordless authentication.

Challenges in Passwordless Authentication

Although the world is slowly warming up toward this technology, passwordless authentication still faces a lot of challenges.

User skepticism #

People are used to using passwords, particularly ones that are simple to remember or that we can keep in our browsers. Because of this, it is hard to imagine a future without passwords, and many people doubt its viability.

Even without having to use the new authentication factors for each login session, learning new technologies, and configuring new hardware and programming, biometric authentication factors may be irritating.

Deployment expense and work #

The implementation of passwordless authentication is not a simple process. A thorough, step-by-step strategy is necessary to integrate new software or hardware and educate staff. The development and implementation of a project and change management strategy consume time that may be spent on other chores or strategic projects.

Deployments with passwordless authentication are similarly expensive. If you choose the hardware path, you must purchase gadgets, tokens, or cards for each employee, as well as extras in case any are damaged or lost in the future.

Security restrictions #

Although passwordless authentication is a vast improvement over traditional password systems, it is not a panacea. Assaults like malware, man-in-the-browser attacks, and others are still conceivable with passwordless authentication.

Attackers have copied even voice recordings and other biometric elements. Nevertheless, selecting the authentication factor(s) will restrict these threats.

BottomLine: Is the future passwordless? #

Passwords are simple and inexpensive, but passwordless is predicted to become the norm in the near future. Cyberattacks have increased more than ever during the past two years. With increasing expenditures being made on biometrics and adaptive authentication, this is raising red flags in many businesses. Additionally, a lot of businesses now understand that passwords are the main cause of data breaches. When compared to the penalties and damages brought on by a data breach, the expense of deploying passwordless is negligible.
