Let’s take one example and say that the user visits the website Enlight Info. Let’s say that the user had already seen Enlight info previously from another device and generated a passkey.

Short Demo on How it works

When the user prefers to login into the device using the passkey from another device, those two devices will connect with each other. Another important thing is that the passkey isn’t itself transferred from devices. Instead, it will offer the user to create a new passkey in the device they will be logging in from.

Why is a passkey so secure?

  • Passkeys cannot be guessed and reused, unlike passwords.
  • They are immune to phishing. Passkeys are exclusive to the program or website they are made for, so a bad actor cannot deceive you into using them on a fake or similar website.
  • Cybercriminals can’t obtain your passkeys by breaking into the provider’s server or database because they are only saved on your device.

Why is a passkey so easy to use?

They are easily created using the device’s security method, Touch Id, Face Id, etc. Since the Passkey that is generated will be stored in the user’s own respective devices in the encrypted format.
