This article will provide an overview of YubiKey and WebAuthn, outlining their differences and similarities and discussing which one may be better for a specific use case.
- Yubikey
- WebAuthn
- Multi-factor Authentication (MFA)
YubiKey and WebAuthn are two different technologies that provide strong authentication for online services. YubiKey is a hardware-based authentication device produced by Yubico, while WebAuthn is a standard for web authentication developed by the World Wide Web Consortium (W3C).
YubiKey provides two-factor authentication (2FA) by requiring something that is possessed (the YubiKey device) and something known (a password or PIN). The YubiKey generates one-time passwords (OTP) or FIDO2 tokens, which can be used to authenticate with a wide variety of online services. YubiKey devices are available in various form factors, including USB, NFC, and Lightning, and can be used with a wide range of devices, including desktops, laptops, smartphones, and tablets.
WebAuthn, on the other hand, is a standard for web authentication that enables users to authenticate with online services using a wide range of devices, including YubiKeys. WebAuthn allows users to authenticate with their devices using biometric data, such as fingerprint or facial recognition, or by using a PIN or password. WebAuthn is supported by all major web browsers and can be used with a wide range of online services.
Which is better really depends on the specific use case and requirements. YubiKey provides a more secure 2FA option, as it requires a physical device to authenticate, while WebAuthn provides a more flexible authentication option, as it allows users to authenticate using a wide range of devices and methods. However, it's worth noting that YubiKey can be used with WebAuthn, so it's possible to combine the two technologies for even greater security and flexibility.
