The ActivIdentity (HID) security token has been used for over a decade at ECMWF, replacing similar RSA tokens which were used before. These tokens provide a second factor for user authentication alongside a user's password, enabling strong authentication for security sensitive services such as login access to ECMWF's Unix systems and services such as ECPDS.
ECMWF is replacing the ActivIdentity tokens with the use of a Time-Based One-Time Password authenticator application, more accurately known as TOTP Client ("time-based one time password"). Typically, the TOTP clients are implemented on a smartphone, but they can also be installed in your laptop or any other computing devices. The Client is synchronised with systems at ECMWF by following the instructions at TOTP: How to activate. Clients usually use PIN codes, or biometric features, for protection.
