SCRAM¶

Salted Challenge Response Authentication Mechanism (SCRAM) is the default authentication mechanism for MongoDB.Salted Challenge-Response认证机制（SCRAM）是MongoDB的默认认证机制。SCRAM is based on the IETF RFC 5802 standard that defines best practices for implementation of challenge-response mechanisms for authenticating users with passwords.SCRAM基于IETF RFC 5802标准，该标准定义了用密码验证用户的质询-响应机制实现的最佳实践。

Using SCRAM, MongoDB verifies the supplied user credentials against the user’s name, password and authentication database.使用SCRAM，MongoDB根据name、password和authentication database验证提供的用户凭据。The authentication database is the database where the user was created, and together with the user’s name, serves to identify the user.身份验证数据库是创建用户的数据库，与用户名一起用于标识用户。
