SSH keys for logging into websites. Like SSH keys there is a public and private key pair, and you never actually send your private key to the website, rather it is confirmed in a challenge/response pattern that proves you have the matching key. This means you can’t accidentally give your passkey to a phishing website or lose it in a data breach (of the website you are logging into) because it never gets sent to a website in the first place. You can register multiple passkeys for a given website/account. You can sync and share passkeys via password managers like 1Password, iCloud Keychain, KeepassXC, etc.
