Definition
A Yubikey is a physical hardware authentication device used in multi-factor authentication. They enhance security by requiring a physical token in addition to passwords.
Example of Using the Yubikey
First, register the device you want to protect on an online service. When logging in, you’ll input your credentials as usual, and then you’ll be prompted to enter the Yubikey and press the button to confirm your authorisation.
How Does Yubikey Work?
Yubikey operates based on 2FA (two-factor authentication) principles and cryptographic methods. It is a small hardware device that connects to your device through a USB port, although some models support wireless connectivity.
Each Yubikey has a unique identifier and cryptographic keys embedded in its firmware to ensure a distinct identity.
What is YubiKey Used for?
- Hardware encryption: Some Yubikey versions offer hardware-based encryption. These may be employed to encrypt emails, files, and other delicate data, offering extra layers of security from data breaches or unauthorized access.
- Secure remote access: Yubikey enables users to access remote networks and systems securely by providing extra authentication.
- Identify verification: Yubikey is a great identity verification tool. For example, it can verify users when performing sensitive operations like digital signatures, online transactions, and safe document exchange.
- Compliance requirements: Yubikey can help to fulfil the compliance requirements of organizations that demand robust security measures.
- Online platforms and services: Yubikey is compatible with multiple online platforms and services, enabling users to strengthen their account security.
- No password sign-in: Yubikey offers a password-free sign-in option, making it more convenient and secure than the traditional authentication password-based methods.
- Password managers: Integrating Yubikey with password managers provides extra protection for retrieval and storage.
