But first, let's check some small concepts.

## In a hurry? { #in-a-hurry }

If you don't care about any of these terms and you just need to add security with authentication based on username and password *right now*, skip to the next chapters.

## OAuth2 { #oauth2 }

OAuth2 is a specification that defines several ways to handle authentication and authorization.

      hostname += "."
    }
    if (!pattern.endsWith(".")) {
      pattern += "."
    }
    // Hostname and pattern are now absolute domain names.

    pattern = pattern.asciiToLowercase()
    // Hostname and pattern are now in lower case -- domain names are case-insensitive.

    if ("*" !in pattern) {
      // Not a wildcard pattern -- hostname and pattern must match exactly.

Notice that now we don't create a default instance `settings = Settings()`.

### The main app file { #the-main-app-file }

Now we create a dependency that returns a new `config.Settings()`.

/// tip

We'll discuss the `@lru_cache` in a bit.

For now you can assume `get_settings()` is a normal function.
