Hello, & Welcome to Tom's Hardare Forum!
At work, you have a Network or regular Systems Administrator who manages your computer system. The have set up their network to require a password to connect to their common gateway.
You should ask the Administrator permission to connect the business computer to the Internet, and if OK, ask him for a password that will give you access to that resource.
He may not want the business computers to be personally connecting to the Wild Wide Web.
