當我們登入自己的應用（可能也有自己的前端）時，這是合適的。

因為我們可以信任它接收 `username` 與 `password`，因為我們掌控它。

但如果你要打造一個讓他人連接的 OAuth2 應用（也就是你要建立一個相當於 Facebook、Google、GitHub 等的身分驗證提供者），你應該使用其他流程之一。

最常見的是 Implicit Flow（隱式流程）。

最安全的是 Authorization Code Flow（授權碼流程），但它需要更多步驟、實作也更複雜。因為較複雜，許多提供者最後會建議使用隱式流程。

/// note

很常見的是，每個身分驗證提供者會用不同的方式命名他們的流程，讓它成為品牌的一部分。

但最終，他們實作的都是相同的 OAuth2 標準。

This document explains the design approach of server side bucket replication. If you're looking to get started with replication, we suggest you go through the [Bucket replication guide](https://github.com/minio/minio/blob/master/docs/bucket/replication/README.md) first.
