MySQL provides a variety of authentication mechanisms, including: Password authentication: requiring user name and password. Plug-in authentication: using external modules or programs. Temporary authentication plugin: Generate one-time token or password. HTTP/HTTPS authentication: Use HTTP or HTTPS protocol. LDAP authentication: Use an LDAP server. MySQL authentication protocol: Custom authentication protocol. Choosing the appropriate authentication mechanism depends on security requirements, deployment environment, and performance considerations.
MySQL Authentication Overview
MySQL provides a variety of authentication mechanisms to protect the database from unauthorized access . These mechanisms include:
1. Password authentication
Password authentication is the most common authentication method, which requires users to provide a username and password to connect to the MySQL server. The password is stored in the authentication plugin, such as mysql_native_password or caching_sha2_password.
2. Plug-in authentication
Plug-in authentication allows the use of external modules or programs for authentication. Common plugins include:
3. Temporary authentication plug-in
Temporary authentication plugin allows users to generate a one-time token or password that can be used for a short period of time. Common temporary authentication plugins include:
4. HTTP/HTTPS authentication
This authentication method uses the HTTP or HTTPS protocol Perform certification. It allows connecting to a MySQL server using GET or POST requests (and Basic or Digest authentication).
5. LDAP Authentication
LDAP authentication uses the Lightweight Directory Access Protocol (LDAP) for authentication. It allows user authentication from an LDAP server.
6. MySQL Authentication Protocol
MySQL Authentication Protocol is a custom protocol used for authentication between the server and the client. It uses an encrypted challenge-response process to authenticate users.
Choose the appropriate authentication mechanism
Selecting the appropriate authentication mechanism depends on security requirements, deployment environment, and performance considerations. For example:
