Tailscale has introduced passkeys, a secure and convenient alternative to passwords. Passkeys do not require the user to remember yet another password and are unique for each account and site visited. Synchronized across devices using services like Google Password Manager, iCloud Keychain from Apple, and 1Password, each passkey is tied to the specific app or website it was created for, and cannot be phished by a lookalike domain name or fake login page design. Passkeys are available in beta for all tailnets and can be used with various passkey providers, including Apple’s macOS and iOS, Google Chrome and Android, and Yubikey.
