What Is Webauthn?


Webauthn is a new standard for web-based authentication that aims to make it easier and more secure for users to log in to websites and other online services. With webauthn, users can use a variety of different authentication methods, including biometric factors like fingerprints or facial recognition, as well as security keys and other hardware-based authentication devices.

Why Adopt WebAuthn?

One of the key benefits of webauthn is that it allows users to log in to websites without having to remember complex passwords. Instead of using a password, users can simply use their preferred authentication method to verify their identity. This can be especially useful for users who have difficulty remembering complex passwords, or who are concerned about the security of their online accounts.

Another benefit of webauthn is that it can help to reduce the risk of account takeover attacks. With traditional password-based authentication, attackers can often gain access to a user’s account by guessing or cracking their password. But with webauthn, the authentication process is much more secure, making it much harder for attackers to gain access to a user’s account.

One of the key components of webauthn is the use of seccirity key, which are small hardware devices that users can use to authenticate themselves. These security keys are typically USB devices that users can insert into their computer or mobile device, and then use to verify their identity.

The use of security keys can provide a number of benefits over traditional password-based authentication. For example, security keys are much harder to hack or steal than passwords, making them a more secure option for users. Additionally, security keys can be configured to work with multiple online accounts, making it easier for users to manage their online identities.

Application & Adoption

To use WebAuthn, a user must first register their biometric or cryptographic hardware device with the website. This can typically be done through the website’s security settings or account settings page. Once registered, the user can then use their hardware device to log in to the website by simply scanning their fingerprint or inserting their security key into their device.

Some common use cases for WebAuthn include logging in to online banking or other financial services, accessing corporate networks, or logging in to personal accounts on social media or other websites. WebAuthn is also increasingly being used as a way to enable two-factor authentication, providing an additional layer of security for users.


Overall, webauthn is an exciting new standard for web-based authentication that has the potential to make the internet a safer and more secure place for everyone. By providing users with a range of different authentication options, and by making it easier and more secure for users to log in to websites, webauthn has the potential to revolutionize the way we use the internet.
