ePass FIDO Security Keys FAQ
What is an ePass FIDO Key?
The ePass FIDO Key is a reliable and secure authentication device designed to deliver strong two-factor authentication (2FA) using FIDO U2F and FIDO2 standards. With advanced passwordless authentication, the ePass FIDO Key protects your online accounts by adding a powerful extra layer of security beyond just a password. Whether you’re securing personal accounts or enterprise systems, the ePass FIDO Key helps defend against phishing, credential theft, and unauthorized access, making it an essential tool for modern online security.
How does an ePass FIDO Key work?
When logging in to a supported online service, you will be prompted to insert your ePass FIDO Key into your device’s USB port and simply touch the built-in sensor. The ePass FIDO Key then generates a unique cryptographic response that securely verifies your identity with the service. This advanced FIDO2 and FIDO U2F authentication method helps prevent phishing attacks and blocks unauthorized access, ensuring your login credentials remain safe and protected.
How many accounts can I protect with a single ePass FIDO Key?
A single ePass FIDO Key can secure an unlimited number of accounts across various websites, applications, and online services. Each account is assigned a unique cryptographic key pair by the ePass FIDO Key, ensuring maximum privacy, strong security, and protection against identity theft or unauthorized access.
What should I do if I lose my ePass FIDO Key?
If you lose your ePass FIDO Key, most supported services offer secure account recovery options using backup authentication methods, such as recovery codes or another registered security key. To ensure uninterrupted access and enhance account security, it is strongly recommended to register multiple ePass FIDO Keys or other trusted FIDO security keys as backup devices. This redundancy helps maintain seamless access while upholding strong, phishing-resistant authentication.
