How to manage TACACS servers

TACACS (Terminal Access Controller Access-Control System) is a remote authentication protocol to communicate information between a network server and a client. Originally developed by Cisco Systems, the protocol controls access to terminals and network services, allowing system administrators to restrict user command options. TACACS allows passwords to be managed centrally, which is ideal for systems that access many network devices.

senhasegura allows you to use TACACS servers to authenticate yourself simply by configuring them within your senhasegura instance.
