Passkeys: The Password Replacement That Actually Works
No more passwords to remember, reuse, or lose to phishing. Here’s how passkeys work and how to migrate your most critical accounts today.
The short version
Passkeys aren’t just better passwords — they’re a different category
Most people assume the gold standard is a strong password plus an authenticator app. Passkeys beat that combination — not marginally, but structurally. They’re faster to use, impossible to phish, and require zero memorization. If a site supports them, there’s no reason to use anything else.
Password + MFA
A real-time phishing proxy can steal your password and MFA code simultaneously as you type them. The attacker relays them to the real site before the code expires. Both factors, captured in one attack.
Passkeys
Your device signs a challenge that’s cryptographically bound to the exact domain. A phishing site at a lookalike URL gets nothing — the signature won’t verify against the real site’s public key. No code to steal. No secret to replay.
Three threats passkeys eliminate — and one password + MFA can’t fully stop
Logging in with a passkey takes a single biometric confirmation — Face ID, Touch ID, or Windows Hello. No typing, no switching to an authenticator app, no waiting for a code to arrive by SMS. It’s genuinely faster than any password-based flow, including autofill. Security and convenience usually trade off. Passkeys are the rare case where the more secure option is also the more convenient one.
How passkeys actually work Technical overview
Passkeys are the consumer implementation of the FIDO2/WebAuthn standard, a protocol developed by the FIDO Alliance (Apple, Google, Microsoft, and hundreds of other members) specifically to replace password-based authentication.
Registration: When you create a passkey, your device generates a unique public/private key pair for that specific site. The private key never leaves your device. The site receives and stores only the public key.
Sign-in challenge: When you log in, the site sends a cryptographic challenge — a random string tied to the exact domain and timestamp. Your device signs the challenge with the private key.
Verification: The site uses the stored public key to verify the signature. If it checks out, you’re in. No password was transmitted. No secret was shared. A fake site can’t forge a valid signature.
Local authentication: Before signing, your device confirms it’s actually you — via Face ID, Touch ID, Windows Hello, or your device PIN. This local check stays on-device; biometric data is never sent to the server.
Most passkeys today are synced passkeys — stored in iCloud Keychain, Google Password Manager, or 1Password, and restored automatically on new devices. All three are good options, with one gotcha: each passkey must be stored somewhere independent of the account it protects. See the storage section below for details.
Some high-security contexts use device-bound passkeys, where the private key is locked inside a hardware authenticator like a YubiKey and cannot be exported. For most people, synced passkeys in iCloud Keychain or 1Password strike the right balance.
Setting up passkeys on major accounts Setup: ~2 min per account
Start with accounts that have the highest risk: email (controls account recovery everywhere), financial accounts, and development platforms. Below are the exact paths for the most common services.
Google Account
Your Google passkey requires special attention. Do not store it in Google Password Manager — you need to already be signed into Google to access GPM, which makes it useless as the key to unlock Google itself. Store it in iCloud Keychain (Apple devices) or 1Password instead.
Apple Account
Apple devices automatically create and manage a passkey for your Apple Account — nothing to set up. For other sites you visit, passkeys are saved to Settings → Passwords on iPhone, or System Settings → Passwords on Mac, and sync across your Apple devices via iCloud Keychain.
GitHub
Critical for developers. A compromised GitHub account can mean code injection into your projects or your employer’s.
Keep your existing password (stored in your password manager) as a fallback until passkeys are broadly supported across all your devices. Some sites require a password for certain flows, like adding a new device when all your passkey-capable devices are offline.
Where to store your passkeys
All three major options — iCloud Keychain, Google Password Manager, and 1Password — are solid choices for most passkeys. The one exception that trips people up: your Google passkey specifically cannot live in Google Password Manager.
GPM requires you to be signed into Google to access it — so it can’t be the key that signs you into Google in the first place. It’s a deadlock. GPM is perfectly good for your bank, GitHub, airline accounts, and everything else. Just store your Google account passkey in iCloud Keychain or 1Password, which are independent of Google.
iCloud Keychain
Free, E2E encrypted, syncs across iPhone, iPad, and Mac. The right default for Apple users. Independent of Google — safe for your Google passkey.
1Password
Works across Apple, Android, Windows, and Linux. Independent of any single platform — can safely hold your Google passkey, Apple passkey, and everything else in one place.
Google Password Manager
Free, built into Android and Chrome. Great for non-Google accounts — your bank, travel sites, social accounts. Not for your Google account itself (see gotcha above).
Apple, Google, Microsoft, and third-party managers like 1Password and Bitwarden all have their own passkey sync systems — and they don’t talk to each other. If you create a passkey in Chrome on a Mac, it may land in Google Password Manager. Do the same in Safari and it goes to iCloud Keychain. End up with passkeys scattered across multiple systems and you’ll find yourself unable to sign in from a device that doesn’t have the right one. Pick one manager as your home base and consistently direct passkeys there.
1Password stores and syncs passkeys across Apple, Android, Windows, and Linux — keeping them alongside your existing passwords in one place, independent of any single platform.

Where passkeys still fall short
Passkeys are a genuine leap forward, but adoption is still uneven. Knowing the limitations helps you avoid getting locked out.
Not all sites support them yet
Most banks, insurance companies, and government services haven’t implemented passkeys. Keep your password manager for these — and push for passkey support when sites offer feedback forms.
Account recovery is on you
If you lose access to all your passkey-capable devices and your backup manager, recovery depends on the site’s fallback process — usually email-based. Keep recovery codes for critical accounts in an offline location (printed and stored securely).
Shared account access is awkward
Passkeys are tied to the device that created them. Sharing login access with a partner means using a shared manager (like 1Password Family) or maintaining a backup password for that account.
Malware on your device is still a threat
Passkeys eliminate phishing and server breaches, but they don’t protect against malware that can observe your authenticated session after login. Keep your devices patched. See the foundational security guide for baseline device hygiene.
