“Passkeys, unlike user-created passwords, are strong and unique by default. These are produced and saved on your devices, and they are never shared with our cloud service,” according to the business. “Passkeys are also immune to phishing, and they feature a full 256 bits of entropy to prevent cracking – offering even more safety than our Secret Key. Biometrics and hardware-level security protect them. And we’re making them portable across all of your devices and platforms.”
