In order to establish a VPN to a company firewall, Joe, a technician needed to have an RSA token and provide a user name and password to connect to the main office. This is an example of:

Privacy filters are physical screen overlays that prevent visual shoulder-surfing and are unrelated to authentication mechanisms.

'Extensive security' is not a recognized technical authentication term or standard.

Two-factor authentication (2FA) requires verification using two distinct factor categories: something you know (the username and password), and something you have (the RSA token that generates a time-based one-time code). Because both factors come from different categories, a compromised password alone is insufficient to gain access. This is standard practice for securing VPN connections to corporate firewalls.

Basic authentication involves only a single factor - a username and password - and does not include a second independent factor like a hardware token.
