RSA SecurID is a widely-used two-factor authentication method based on the use of SecurID Authenticator tokens. In SSH Tectia, support for RSA SecurID is enabled as a submethod of keyboard-interactive authentication.

The prerequisite for enabling SecurID support in SSH Tectia Server is that RSA Authentication Agent software is installed on the server host. When RSA SecurID is used, SSH Tectia Server queries the user for the token's numerical code and passes the code to RSA Authentication Agent for verification. RSA Authentication Agent then returns the success or failure of the authentication to SSH Tectia Server.
