Passwordless authentication | How Passkeys Work | Johor Web Design

Passwords have been part of our online lives for a long time, but they come with a lot of problems. They’re hard to remember, easy to guess, and often stolen in data breaches. Many people reuse the same password across different sites, which makes things even riskier.

Now there’s a better way to sign in called passkeys. Passkeys are safer, easier to use, and don’t require you to remember anything. In this post, we’ll explain what passkeys are, how they work, and why they could replace passwords in the near future.

What Are Passkeys?

A passkey is a digital credential that replaces your password. Instead of something you have to remember (like “Tr0ub4dor&3”), a passkey uses cryptographic keys stored on your device. It is a FIDO-based authentication credential that allows users to log in to apps and websites using the same method they use to unlock their devices such as a fingerprint, facial recognition, or a PIN.

Here’s how it works:

• When you sign up for a site using a passkey, your device creates a pair of keys: one public, one private.
• The public key is saved on the website’s server.
• The private key stays safely on your device.
• To log in, you confirm your identity using something like Face ID, a fingerprint, or a PIN. Your device proves it has the private key and there is no password required.

This method is built on a secure standard called WebAuthn, developed by the FIDO Alliance in partnership with major tech players.

Are Passkeys Secure?

1. They Can’t Be Phished

Passkeys only work with the original website. So even if a scammer builds a fake login page, it won’t fool your device into handing over your credentials.

2. There’s Nothing to Steal

Since the private key never leaves your device, there’s no password database to hack. A major breach won’t expose your login info.

3. They’re Super Convenient
Logging in with a passkey is as easy as unlocking your phone. No typing. No forgetting. No “Reset My Password” loop.

4. They Work Across Devices

Thanks to cloud syncing, passkeys can follow you across your devices, whether you’re on iOS, Android, macOS, or Windows (depending on your ecosystem or password manager).

Where Can You Use Them?

Passkeys are already supported on:

• Apple devices (iPhone, iPad, Mac)
• Android and Chrome
• Windows 10/11 with Edge
• Password managers like 1Password and Dashlane

Major platforms like Google, PayPal, Amazon, and TikTok have rolled out support. And many more are on the way.

Conclusion

We’ve been using passwords for decades, but they’ve caused more trouble than security. Keys offer a cleaner, safer, faster way to log in, and they’re here. If you’re ready to say goodbye to passwords, try enabling Passkey on your Google or Apple account. It’s surprisingly easy, and once you do, you may never want to go back.
