Google Chooses Passkeys Over Passwords: Examining the Security Benefits for Linux Users

While Apple’s iOS is next in line, this widespread rollout marks a significant milestone in the broader trend of passwordless authentication. Let's examine the security benefits passkeys offer over passwords and how you can get started with passkeys on Linux today! 

Understanding Passkeys vs. Passwords

When evaluating the pros and cons of passwords and passkeys, it is important to highlight their distinct characteristics and advantages. Passwords are a universally accepted and understood authentication method, offering a straightforward approach for users. However, they come with significant drawbacks, such as susceptibility to brute force and phishing attacks, the necessity for users to remember complex characters, and the fact that even when stored as hashes, they can still be cracked with sufficient computational power.

On the other hand, passkeys present a more secure alternative, notably resistant to phishing and brute force attacks. They provide a streamlined user experience, primarily using biometrics or device PINs for authentication, and their end-to-end encryption ensures that even companies like Google cannot access the key. Despite these advantages, passkeys currently have a limited rollout and require compatible devices, making them dependent on hardware for biometric authentication.

How Do Hackers Crack Passwords?

Hackers employ several methods to crack passwords, including:

• Brute Force Attacks: Involves systematically trying every possible combination until the correct one is found. Although effective, it requires significant computational power.
• Phishing: Deceptively obtaining user credentials by masquerading as a legitimate entity.
• Keylogging: Using malware to record keystrokes as users type their passwords.

Most services store passwords as hashes—a one-way math function that converts plaintext to a fixed-length binary sequence. However, with enough computational resources, even hashed passwords can be cracked using brute force.

How Do Passkeys Mitigate Risk?

Passkeys mitigate these risks by eliminating the need for raw password strings. Since passkeys rely on device-specific cryptographic keys and biometrics, hacking attempts would require physical access to the user's device and biometric data, making remote attacks near impossible.

Getting Started with Passkeys on Linux

Ready to make the switch? Linux users can get started using passkeys to improve their online security and privacy by following these steps:

• Ensure Your System is Updated: Ensure your OS and Google Chrome are updated to the latest versions supporting passkeys.
• Set Up Google Password Manager: Use the built-in password manager in Chrome, setting a strong PIN for added security.
• Enable Biometric Authentication: If your device supports biometrics, enable this in your system settings.
• Sync Across Devices: Log into your Google account and sync the passkeys across your devices.

Security Considerations

Although passkeys offer inherent security benefits, it is crucial to engage in the following security best practices when using them:

• Device Security: Ensure your device is secure from physical theft and unauthorized access.
• Strong PINs: If using a PIN instead of biometrics, ensure it is strong and unique.
• Regular Audits: Review your security settings to ensure they align with best practices.

Our Final Thoughts on Passkeys vs. Passwords for Improved Security

Google's move towards integrating secure passkey sign-ins across various devices signifies a pivotal step towards a passwordless future. By leveraging passkeys, users can enjoy a more secure, seamless authentication process that dramatically reduces the risk of traditional password-related attacks. As we move further into this new era of cybersecurity, embracing technologies like passkeys will undoubtedly play a crucial role in protecting our digital identities.
