各「スコープ」は（スペースを含まない）単なる文字列です。

通常、特定のセキュリティ権限を宣言するために使われます。例えば:

- `users:read` や `users:write` はよくある例です。
- `instagram_basic` は Facebook / Instagram で使われます。
- `https://www.googleapis.com/auth/drive` は Google で使われます。

/// info | 情報

OAuth2 における「スコープ」は、要求される特定の権限を表す単なる文字列です。

`:` のような他の文字を含んでいても、URL であっても構いません。

それらの詳細は実装依存です。

OAuth2 にとっては単なる文字列です。

### Security vulnerabilities

* Using kubectl gcp auth plugin with a Google Service Account to authenticate to a cluster now additionally requests a token with the  "userinfo.email" scope. This way, users can write ClusterRoleBindings/RoleBindings with the email address of the service account directly. (This is a breaking change if the numeric uniqueIDs of the Google service accounts were being used in RBAC role bindings. The behavior can be overridden by explicitly...
