Overview of authentication and accounts
- [Instructor] In this section, we're going to talk about authentication and how it relates to security in Windows 11. Authentication is defined as confirming the truth of a single piece of data. In relation to security, that basically means verifying that you are who you say you are. So if you walk up to a computer and claim that you are the administrator of that computer, the computer is not just going to take your word for it. It's going to require that you prove somehow that you are the administrator, and typically this happens with passwords. In all versions of Windows, authentication is tied to accounts. An account is an entity that should be controlled by a single user. An account is attached to permissions, or we could say that permissions are attached to accounts, but basically an account has the permissions to read certain files, write certain files, it might even be denied permission to do certain things on the computer. And in order to maintain security, every account needs to be authenticated in some way, typically, a password. In Windows 11, when you create a new account, it will try and link it to a Microsoft account. Microsoft accounts are free accounts that are based on an email address and they are used to login to microsoft.com and several other websites. Microsoft would like for you to use that same login to access your account on your local Windows 11 PC, but you don't have to. It is possible to create an account on Windows 11 that is not linked to a Microsoft account and only exists on the local PC.
