What is Google Passkeys Default Sign-in?

Passwords are a weak point of signing in online: people have to remember them, and attackers try to steal them through phishing and similar remote attacks, so passkeys are an alternative. A passkey is a pair of cryptographic keys, so you can prove who you are without revealing a secret key. Google Passkeys Default Sign-in is Google's setting that offers passkeys as the default way into personal Google Accounts, so you unlock your device with a fingerprint, face scan or phone screen lock instead of typing a password. Google's help page says that, unlike passwords, passkeys can't be shared, copied or written down. Google announced the change on October 10, 2023.
