Using authentication

- [Voiceover] In this section I'd like to talk…about authentication on a small network.…Authentication is when you prove that…you are who you say you are.…In other words if I walk up to a machine…and I tell that machine, "I am the administrator."…It doesn't just take my word for it.…I have to do something to prove I am the administrator,…and typically that is typing in a password.…Most of our authentication is…based on username and password.…On a small network we can have authentication…done by each individual machine.…

So each machine would maintain its…own list of usernames and passwords.…In some operating systems the requirement…for a password is optional.…I usually recommend turning that on.…Go ahead and force every account to need…a password in addition to the username.…And these usernames will be used for our…file sharing so if you want to do file sharing,…making sure everyone has their…own account is very important.…If you use the local machine to do…your authentication you may have to create…accounts on multiple machines.…
