Readers reply: Experts say we should use passkeys, but can a smartphone pin really be safer than a password?
Summary
Passkeys, which use a device-based code or biometric data like a fingerprint, are being recommended as safer than traditional passwords. Unlike passwords, passkeys are stored only on your device and are hard for hackers to steal or reuse, even if a website is hacked.Key Facts
- Passkeys can be a PIN on your phone or a biometric check like facial recognition.
- They do not get stored on company servers, making them less vulnerable to hacking.
- If your phone is lost or stolen, you can quickly cancel your passkeys to protect accounts.
- Passwords are “shared secrets” sent to websites; if hacked, they can be stolen and reused.
- Passkeys use complex math so only a proof (not the key itself) is sent to websites, keeping the passkey safe.
- Passkeys are easier to use and less likely to be “phished” (tricked out of you).
- Users can enable extra phone security features like “Stolen Device Protection” and “Lockdown Mode” for better safety.
- Some people still find passkeys confusing and prefer traditional passwords and two-factor authentication.
