Zero Trust Network Access (ZTNA) is a security solution that provides secure remote access to corporate resources based strictly on identity and context. Identity verification for every person and device is required continuously regardless of network location or whether they have previously accessed a resource or not. No one is trusted from inside the network or outside, which is a tighter ship than the traditional approach of one being universally trusted as long as they are inside the network.

 authentication allowing web servers to authenticate users with asymmetric cryptography instead of passwords. Users can use their own devices, like security keys or smartphones, to authenticate themselves to a website. By eliminating passwords altogether, WebAuthn provides a more secure and convenient way for users to access their personal information and accounts online.

WebAuthn, or Web Authentication API, is a standard developed by W3C and FIDO, launched in 2018, and became the 

 for passwordless logins, supported by Chrome, Firefox, Safari, Microsoft Edge, Windows 10 and Google Android.


WebAuthn is very secure in that it uses public key cryptography ensuring that only a user’s device can authenticate that user to a website and that the keys involved are specific to that origin or domain. This removes the many risks that revolve around passwords and the broader danger of phishing attacks. In addition, the fact that users no longer need to remember or maintain complex passwords make WebAuthn very convenient as they can simply use their device to authenticate. And as a bonus, WebAuthn is considered multifactor in itself because it’s something you have (their device) with something you are (biometric).


WebAuthn utilizes asymmetric, public key cryptography. This means upon initial registration two keys are created:

A public key, which can be shared publicly and will be encrypted and stored by the website or service.

A private key, which should always remain private, is stored locally in a trusted platform module and can’t be stolen like a password. The private key is used to sign an attestation from the user, verifying that the user is indeed who they say they are.

The public key can be decrypted only with the private key, and the public key alone cannot mathematically reveal the private key in any way.

Now there are three key terms that must be defined to understand how the WebAuthn flow works:

 This is a website or application that needs to authenticate users.

 This is an operating system or browser used by the user to authenticate.

 This is a mechanism that accepts the user input to authenticate the user’s credential for the relying party. It can be an internal authenticator such as a secure enclave via fingerprint reader or facial recognition, or an external authenticator such as a Yubikey connected to your computer.

Let’s imagine that a user named Alice wants to sign up for online banking with a new bank that supports WebAuthn. Here’s what the registration flow would look like using our key terms above:

Alice initiates the action to register a new account with her bank. The relying party (bank application) makes a 

 request to the client (Alice’s browser) with some data such as user information, information on the relying party, and a challenge (needed to prevent “replay attacks”).

The request, with its data, gets sent to the authenticator.

The authenticator prompts the user to take some action (tap a security key, touch the fingerprint module) upon which it will create a unique set of credentials, a public and private key pair.

The authenticator sends the public key to the relying party along with other data verifying the origin that came in the request.

The relying party verifies the response and saves the user data together with the new public key. The origin data it receives from the request helps to prevent phishing attacks. The registration is now finished.

Going forward when Alice logs in, instead of a 

 request will be sent to the client, and instead of the authenticator creating unique keys, the authenticator sends a response signed with the private key, and the relying party will verify.
