在web应用程序中有什么不同?我经常看到缩写“auth”。它是代表认证还是授权?或者两者都有?


当前回答

身份验证是验证您的登录用户名和密码的过程。

授权是验证您是否可以访问某些内容的过程。

其他回答

身份验证是验证所宣布的身份的过程。

例如,用户名/密码

通常接下来是授权,也就是批准你可以这样做或那样做。

如权限

Authentication是一个验证的过程:

系统中的用户身份(用户名、登录名、电话号码、电子邮件……),通过提供证明(密钥、生物识别、短信……)作为扩展的多因素身份验证。 使用数字签名检查电子邮件[关于] 校验和

授权是身份验证之后的下一步。它是关于资源的权限/角色/特权。OAuth(开放授权)是授权的一个例子

  Authentication Authorization
What does it do? Verifies credentials Grants or denies permissions
How does it work? Through passwords, biometrics, one-time pins, or apps Through settings maintained by security teams
Is it visible to the user? Yes No
It is changeable by the user? Partially No
How does data move? Through ID tokens Through access tokens

认证是验证实体身份的过程。例如

Webserver每次都要求用户输入登录名/密码,以验证创建该帐户的用户是否是现在正在访问该帐户的用户。

授权是允许每个实体获得所需数量的服务/资源的过程。例如

On blogging site (eg. medium.com) users can create an account and write a post and publish. And users can read all posts published by others as well. Here the blogging server first authenticates the user with the user login credentials (login/password) and then it authorizes to read all others post and write/modify the post only created by the user. Here authorization is used by the server to limit which all post each user can modify. Users can create a free google account by which google server provides free services like mail, calendar, chat, drives etc. But the storage provided for all these services to free users are 15GB (as of now). User can pay a monthly or annual fee to google server to increase the storage space. Here google server authorizes every authenticated user to limit the amount of resource usage.

在当今的互联网中,授权被广泛用于对客户端施加访问限制。

简而言之,请。: -)

身份验证=登录名+密码(你是谁) 授权=权限(你被允许做的事情)

简短的“auth”最有可能指的是第一个或两者。
