What is a Passkey?
A passkey is a cryptographic key pair stored on your device. To log in: site sends a challenge → iPhone signs it with private key → done. No password to type, no password to phish, no password to leak.
Why Passkeys Are Safer
- Phishing-proof — passkey only works on real domain
- Breach-proof — server only stores public key
- No reuse — different passkey per site
- Biometric-locked — Face ID/Touch ID required to use
- Backup via iCloud — never lose if device dies
Sites That Support Passkeys (2026)
Google, Amazon, GitHub, Apple ID, Microsoft, PayPal, eBay, Best Buy, Costco, Target, X (Twitter), Adobe, Discord, Bestbuy, Walmart, TikTok, Robinhood. Most major banks coming 2026-2027.
How to Set Up a Passkey
- Visit site (e.g., amazon.com)
- Account → Security → 'Set up Passkey'
- iPhone Face ID prompt → confirm
- Done. Next login: Face ID instead of password.
If You Lose Your iPhone
Passkeys are backed up to iCloud Keychain (encrypted with your Apple ID password). Get a new iPhone, sign into Apple ID, all passkeys restore. As safe as iCloud is — which is very safe.
