## Features
|
||
|
|
### 1. **Two-Factor Authentication (2FA):**
|
||
|
|
- YubiKey supports one-time password (OTP) generation, adding an extra layer of security to your accounts by requiring something you know (password) and something you have (YubiKey).
|
||
|
|
### 2. **Universal Second Factor (U2F):**
|
||
|
|
- YubiKey implements the U2F standard, allowing it to be used as a hardware token for two-factor authentication with websites and services that support U2F.
|
||
|
|
### 3. **OpenPGP and Smart Card Support:**
|
||
|
|
- YubiKey can be configured to act as an OpenPGP smart card, enabling secure [email](../internet/eMail.md) communication and digital signatures.
|
||
|
|
### 4. **FIDO2 and WebAuthn:**
|
||
|
|
- YubiKey supports FIDO2 and WebAuthn standards, providing passwordless authentication for a growing number of online services and platforms.
|
||
|
|
### 5. **NFC (Near Field Communication):**
|
||
|
|
- Some YubiKey models include NFC support, allowing for easy authentication with mobile devices by tapping the YubiKey.
|
||
|
|
|
||
|
|
## Getting Started
|
||
|
|
### 1. **Registering YubiKey:**
|
||
|
|
- To use YubiKey with supported services, you typically need to register it. Follow the service-specific instructions to associate your YubiKey with your account.
|
||
|
|
|
||
|
|
### 2. **Configuration and Personalization:**
|
||
|
|
- Use the [YubiKey Personalization Tool](https://www.yubico.com/products/services-software/personalization-tools/) to configure and personalize your YubiKey. This includes setting up static or dynamic passwords and enabling or disabling specific features.
|
||
|
|
|
||
|
|
### 3. **Using YubiKey:**
|
||
|
|
- When prompted for authentication, insert your YubiKey into a USB port or tap it on an NFC-enabled device. The YubiKey generates or validates the required authentication codes.
|
||
|
|
|
||
|
|
## Security Considerations
|
||
|
|
1. **Physical Security:**
|
||
|
|
- Keep your YubiKey physically secure. Treat it like a key to your accounts and store it in a safe place.
|
||
|
|
2. **Backup Options:**
|
||
|
|
- Consider having backup authentication methods in case you lose your YubiKey.
|
||
|
|
3. **Firmware Updates:**
|
||
|
|
- Regularly check for firmware updates and apply them to ensure your YubiKey has the latest security enhancements.
|
||
|
|
4. **Service Compatibility:**
|
||
|
|
- Ensure that the online services you use support YubiKey and the desired authentication standard.
