Comments @ Zhong Yunlong Daoist supplement:
1. Email Verification
For most sites that use a mailbox as an ID, a verification URL is usually sent to verify that you are the owner of the message (in fact, it is not necessary), the basic principle is simple, add 2 fields to the user table: A randomly generated verification code and a validation status. The verification code is included in the URL sent by the mailbox.
2. OAuth
OAuth is currently an agreement to register and sign in with a third-party account, and the latest version is OAuth 2.0. The most commonly used three-party account is Weibo and QQ, foreign is Google, Facebook and so on. Before using them, you need to make a request for the account, get Appkey and Appsecret, set the redirect Uri, and sometimes need to download the relevant SDK for a series of configurations to use. / http blog.xuite.net/gotrans/ life/13801477-php+-+php+session+%e4%bd%bf%e7%94%a8%e5%85%a5%e9%96%80
