What are passkeys and how do they make online accounts safer?

Passwords have protected online accounts for decades, but many websites and apps are now offering a simpler alternative called passkeys. Instead of remembering long passwords or typing verification codes, you can sign in using your fingerprint, face recognition or your device’s PIN.

According to Finansmagasin.no, passkeys are designed to make logging in both easier and more secure. While the technology may sound complicated, getting started is often much simpler than many people expect.

What are passkeys?

A passkey is a digital credential securely stored on your phone, tablet or computer. Rather than entering a password every time you log in, you simply verify your identity using your device’s built-in security features, such as Face ID, fingerprint recognition or a PIN.

As Finansmagasin.no explains, passkeys rely on cryptographic key pairs. One part of the key is stored securely on your device, while the matching public key is stored by the website or service you’re using. Only your device can complete the authentication process, making it far more difficult for attackers to gain access.

Why passkeys are more secure

Traditional passwords can be guessed, stolen, reused or exposed in phishing attacks and data breaches. Passkeys eliminate many of these risks because there is no password for users to type or accidentally reveal.

Even if a company’s servers are compromised, attackers cannot use the stored public key to access your account. The private portion of the passkey never leaves your device, significantly reducing the risk of credential theft.

Everyday benefits

Beyond stronger security, passkeys make signing in much faster.

Instead of entering your email address, password and a one-time verification code, logging in often requires nothing more than unlocking your device with your fingerprint, face or PIN.

According to Finansmagasin.no, this can save time while also reducing the frustration of forgotten passwords and repeated password resets.

What you need to get started

Most modern smartphones, tablets and computers already support passkeys.

Before setting one up, make sure your device is running a recent version of its operating system, whether that’s iOS, Android, Windows or macOS. You’ll also need to have a screen lock enabled using a PIN, fingerprint or facial recognition.

Many platforms also synchronize passkeys through your Apple, Google or Microsoft account, allowing them to be securely available across multiple devices.

Setting up your first passkey

Although the exact steps vary slightly between services, the process is generally similar.

First, sign in to a website or app using your existing password. Then open the account’s security or login settings and look for an option such as “Create Passkey” or “Add Passkey.”

Choose the device you’d like to use, confirm your identity using your fingerprint, face recognition or PIN, and complete the setup. Once finished, you can test the new sign-in method by logging out and selecting the passkey option when signing back in.

Using passkeys across multiple devices

Many people wonder whether a passkey only works on the device where it was created.

Finansmagasin.no notes that, in many cases, passkeys automatically sync through your device manufacturer’s cloud account, making them available on your phone, tablet and other trusted devices.

When signing in on a computer, you may also be asked to scan a QR code with your smartphone. After confirming your identity on your phone, the computer login is completed without requiring a password.

How passkeys work with two-factor authentication

Passkeys already provide a high level of security because authentication requires both your physical device and a way to unlock it, such as biometrics or a PIN.

Some services continue to offer additional security measures, including hardware security keys or authentication apps. These extra layers can be especially valuable for important accounts such as email, banking or financial services.

What if you lose your phone?

Losing a device is one of the most common concerns for new passkey users.

Fortunately, most platforms allow you to recover your passkeys by signing into your Apple, Google or Microsoft account on a replacement device. Once your account is restored, you can continue using passkeys without starting from scratch.

Finansmagasin.no also recommends maintaining a strong, unique password for your primary account and considering a physical security key as an additional recovery option for your most important services.

Start small and build confidence

There’s no need to replace every password immediately.

Instead, begin with one account you use frequently, such as your email or a favorite app, and become comfortable with how passkeys work before expanding to additional services.

As Finansmagasin.no points out, authentication technology continues to evolve, so interfaces and setup processes may change over time. Taking a few moments to read on-screen instructions and keeping your devices updated will help ensure a smooth and secure experience as passkeys become increasingly common.
