Which one is not an example of a physical token?

• a standalone device which generates a token

• a simple key used with a traditional lock

Web Traffic is protected using a protocol called:

• SSH

• HTPST

A RSA secureID (a)   is a small, battery-powered device with an LCD display that shows a One-Time-Password that's rotated periodically. This is a time-based token sometimes called a TOTP, and operates by having a secret seed or randomly generated value on the token that's registered with the authentication server. The seed value is used in conjunction with the current time to generate a One-Time-Password. As long as the user has possession of their token, or can view the display of the token, they are able to log in.
