Passwords have been the weakest link in online security for decades. They get phished, leaked in breaches, reused across sites, and stored in databases that hackers target relentlessly. Passkeys are the long-awaited replacement — a fundamentally different approach to authentication that eliminates passwords entirely while giving you stronger privacy protections. With over 800 million Google accounts already using passkeys and 87% of enterprises deploying them in 2026, the shift is well underway. Here is everything you need to know to make the switch.
What Are Passkeys?
Passkeys are a new type of login credential based on the FIDO (Fast Identity Online) standard. Instead of typing a password, you authenticate using something already built into your device — your fingerprint, face scan, PIN, or screen lock pattern.
Behind the scenes, passkeys use public-key cryptography. When you create a passkey for a website, your device generates two keys:
- A private key — stored securely on your device in a hardware-protected secure enclave
- A public key — shared with the website and stored on their server
When you sign in, the website sends a challenge to your device. Your device uses the private key to sign the challenge, and the website verifies it with the public key. At no point does a password, secret, or biometric data travel over the internet.
Why Passkeys Are Better for Privacy Than Passwords
The privacy advantages of passkeys over traditional passwords are substantial:
No Shared Secrets
With passwords, both you and the website know your secret. If the website gets breached, your password is exposed — often along with millions of others. Passkeys eliminate this entirely. The website only has your public key, which is useless to attackers on its own.
Phishing Resistance
Passkeys are cryptographically bound to the specific website they were created for. If a phishing site mimics your bank's login page, your passkey simply will not work on it. The authentication fails silently because the domain does not match. This makes passkeys immune to the phishing attacks that compromise millions of passwords every year.
Your Biometric Data Never Leaves Your Device
This is one of the most important and misunderstood privacy benefits. When you use a fingerprint or face scan to authenticate with a passkey, your biometric data stays entirely on your device. The website receives only a cryptographic signature — it never sees your fingerprint, face data, or any biometric information. Your biometrics are verified locally by your device's secure hardware, not transmitted or stored anywhere online.
Passkeys Cannot Be Intercepted
Unlike passwords that can be captured by keyloggers, shoulder surfing, or man-in-the-middle attacks, passkeys are cryptographic credentials that cannot be intercepted, reused, or stolen. Even if someone watches you sign in, they cannot replicate your authentication.
No Password Reuse Problem
Password reuse is one of the biggest security risks online. When one site gets breached, attackers try those credentials on every other major service. Since each passkey is unique to each site and cannot be extracted from your device, this entire category of attack disappears.
How to Set Up Passkeys on Major Platforms
Setting Up Passkeys with Google
- Go to myaccount.google.com and sign in
- Navigate to Security and then Passkeys and security keys
- Click Create a passkey
- Follow the prompts to verify your identity with your device's biometric or screen lock
- Your passkey is created and synced across your Google devices via Google Password Manager
Google has been one of the strongest advocates for passkeys, with over 800 million accounts now using them. Once set up, you will be prompted to use your passkey instead of your password when signing in.
Setting Up Passkeys with Apple
- On your iPhone or Mac, go to a supported website or app
- When prompted to create an account or sign in, choose the passkey option
- Authenticate with Face ID, Touch ID, or your device passcode
- Your passkey is automatically saved to iCloud Keychain and synced across all your Apple devices
Apple stores passkeys in iCloud Keychain with end-to-end encryption, meaning even Apple cannot access your passkeys. They sync seamlessly across your iPhone, iPad, and Mac.
Setting Up Passkeys with Microsoft
- Go to account.microsoft.com and sign in
- Navigate to Security and then Advanced security options
- Under sign-in methods, select Add a new way to sign in
- Choose Face, fingerprint, PIN, or security key
- Follow the prompts to create your passkey using Windows Hello or your mobile device
Microsoft supports passkeys across Windows, Edge, and Microsoft 365 services. Windows Hello provides the local biometric verification on Windows devices.
Which Sites Support Passkeys?
Passkey adoption has accelerated dramatically. Hundreds of websites and apps now support passkey authentication, including:
- Major tech platforms: Google, Apple, Microsoft, Amazon (175 million users created passkeys in its first year), GitHub, Nintendo
- Financial services: PayPal, Robinhood, Coinbase, many major banks
- Social media: X (Twitter), LinkedIn, TikTok
- Password managers: 1Password, Dashlane, Bitwarden
- Communication: WhatsApp, Uber, Best Buy, Target, Shopify stores
The directory at passkeys.directory maintains an up-to-date list of all services that support passkey authentication. Check it regularly as new sites add support every week.
Passkeys Deliver Better User Experience Too
Beyond privacy and security, passkeys are simply faster and more reliable. Google reports that passkey sign-ins are 20% more successful than password-based sign-ins — no forgotten passwords, no mistyped characters, no waiting for SMS codes. Authentication takes seconds.
How Passkey Syncing Works
One common concern is what happens if you lose your device. Passkeys are designed to sync securely across your devices:
- Apple devices: Passkeys sync via iCloud Keychain with end-to-end encryption
- Android devices: Passkeys sync via Google Password Manager with end-to-end encryption
- Windows devices: Passkeys sync via Windows Hello and your Microsoft account
If you lose a device, you can access your passkeys from any other device signed into the same account. You can also revoke passkeys for lost devices through each service's security settings.
Cross-Platform Use
Need to sign in on a device that does not have your passkey synced? Most implementations support cross-device authentication. You can use your phone to scan a QR code displayed on a computer, then authenticate with your phone's biometric to complete the sign-in on the other device.
Tips for Transitioning to Passkeys
Making the switch does not have to happen all at once. Here is a practical approach:
- Start with your most important accounts — email, banking, and cloud storage should be your first priorities
- Keep your passwords active during transition — most sites let you use both passkeys and passwords while you get comfortable
- Set up passkeys on multiple devices — ensure you have backup access by creating passkeys on your phone and computer
- Use a password manager that supports passkeys — managers like 1Password and Dashlane can store passkeys alongside your remaining passwords
- Remove passwords after you are confident — once you have verified your passkeys work reliably, consider removing password-based sign-in where the option exists
Do Not Delete Your Password Manager Yet
Many sites still do not support passkeys, and you will need passwords for those accounts for the foreseeable future. Keep your password manager active and continue using strong, unique passwords for sites that have not adopted passkeys. The transition will take time.
Passkeys as Part of Your Overall Privacy Strategy
Passkeys are a powerful step forward, but they are one piece of a broader privacy strategy. Strong authentication protects your accounts, but your personal data is still exposed through data brokers, old breaches, social media oversharing, and public records.
A complete privacy approach combines passkeys for account security with tools like PrivacyOn for removing your personal information from data broker sites, dark web monitoring to catch breach exposures early, and regular privacy audits to stay ahead of new threats.
The era of passwords is ending. Passkeys offer a future where signing into your accounts is simultaneously easier and more private. Every passkey you create today is one fewer password that can be phished, leaked, or stolen tomorrow. Start with your most critical accounts this week — it takes less than five minutes per account, and the privacy benefits last a lifetime.
