 OAuth 2.0 is an open standard for authentication and authorization used by AAD and many other identity providers. A basic understanding of OAuth 2.0 is a prerequisite for working with authentication in Teams; [here's a good overview](https://aaronparecki.com/oauth-2-simplified/) that's easier to follow than the [formal specification](https://oauth.net/2/). Authentication flow for tabs and bots are a little different because tabs are very similar to websites so they can use OAuth 2.0 directly, and bots are not and must do a few things differently, but the core concepts are identical.
