RAdmin can optionally support Yubikey tokens from Yubico (http://www.yubico.com ). Yubico tokens are small USB devices that act like a keyboard and which type in a one-time-password when the button is pressed. They can be purchased from Yubico and issued to your users. Such tokens provide much higher levels of security than static passwords. Yubikey is supported on all RAdmin platforms.

Each Yubikey token has a unique Token ID (also called the public identity in Yubico documentation), and a secret AES cryptographic key. In order to authenticate a Yubikey token, the RAdmin database must contain a Yubikey record containing both the Token ID and the AES secret for that key. You can add new tokens into the RAdmin database with the RAdmin ‘Import Yubikey Tokens’ page. After a token is imported, it must be allocated to a user before that user can use the token to authenticate.
