In today’s digital age, protecting your personal information and online accounts is more critical than ever. Cyberattacks targeting computers, accounts, and sensitive data occur daily, making robust security measures essential. For years, traditional passwords have been the primary method of safeguarding our digital lives. However, passwords come with significant vulnerabilities — many people reuse them across multiple sites, and even strong passwords can be compromised through data breaches. Fortunately, a new technology called passkeys promises to transform online authentication by offering a safer, faster, and more convenient alternative.
**What Are Passkeys and Why Should You Care?**
Passkeys represent a cutting-edge way to verify your identity online without relying on traditional passwords. Instead of typing a password, passkeys use cryptographic technology to prove who you are. When you create a passkey for a website or app, your device generates a pair of keys: one public and one private. The public key is sent to the website, while the private key remains securely stored on your device. During login, your device uses the private key to confirm your identity without ever transmitting it. This process effectively blocks phishing attacks and password theft because your private key never leaves your device, and the website never stores it.
This method not only enhances security but also speeds up the sign-in process since you no longer need to remember or type long, complicated passwords. Passkeys work across most modern devices and browsers, making them a versatile tool for everyday users.
**Can You Use Passkeys Without Biometric Hardware?**
A common question is whether passkeys require biometric features like fingerprint readers or cameras. The answer is no. Passkeys are designed to work on virtually any device, whether or not it includes biometric hardware. For example, on Windows PCs, you can unlock passkeys using your Windows Hello PIN. On Apple devices, you can use Touch ID, Face ID, or your passcode. The key requirement is that your operating system and browser are up to date and support passkeys.
This flexibility means you don’t need to upgrade your computer hardware to take advantage of passkeys. Even if your desktop lacks biometric sensors, you can still use passkeys securely and conveniently.
**Using Passkeys with Password Managers for Cross-Platform Convenience**
While passkeys simplify authentication, they do not completely replace the need for password managers. Password managers remain essential tools as they securely store not only traditional passwords but also passkeys. They can synchronize these credentials across different devices and operating systems — a critical feature since passkey syncing isn’t yet universally supported.
For instance, Apple’s iCloud Keychain securely syncs passkeys within the Apple ecosystem, but it doesn’t extend this functionality to Windows or Android devices. Here, third-party password managers that support passkeys fill the gap by acting as a central vault. This allows you to access passkeys on non-Apple devices or browsers that don’t natively support them. As a result, using a password manager alongside passkeys offers both enhanced security and seamless convenience across platforms.
**Current Limitations and the Importance of Backup Methods**
It’s important to note that not every website supports passkeys yet. Many online services still rely on passwords, and until widespread adoption occurs, you’ll need to maintain strong, unique passwords for those accounts. Passwords also act as a backup if you lose access to your device or encounter issues using your passkey.
Because of this transitional period, password managers are invaluable. They provide a secure storage solution that bridges old and new authentication methods, allowing you to store passwords and passkeys together. This dual approach ensures you can smoothly navigate online security regardless of the site or device you’re using.
**How to Set Up and Use Passkeys on Your Devices**
Setting up passkeys is generally straightforward. On Apple devices, enabling iCloud Keychain is the first step. Once activated, eligible apps and websites will prompt you to create a passkey during login. Simply follow the on-screen instructions to complete the process. For Windows users, passkeys can be accessed and approved using the Windows Hello PIN, even if the device lacks biometric sensors.
If your device does not support automatic passkey syncing, using a password manager that supports passkeys is an excellent alternative. These managers securely store your passkeys and make them accessible across desktops, laptops, and mobile devices. This setup is especially helpful if you use a mix of operating systems, such as Mac and Windows or iOS and Android.
