What are mysql certifications?

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:

• pam:Use system Pluggable Authentication Modules (PAM) for authentication
• gssapi:Use Kerberos or NTLM Authentication
• sha256_password:Use the strong encryption algorithm SHA-256 to store passwords

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:

• auth_token:Generate a one-time token that can be used within a specific period
• auth_p2s:Generate a pre-shared key that allows authentication from the client server

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:

• Password authentication:Works fine for most use cases, but is less secure.
• Plug-in Authentication:Provides enhanced security, but requires additional configuration.
• Temporary authentication plug-in:Suitable for situations where one-time or temporary access is required.
• HTTP/HTTPS Authentication:Suitable when using a web application to connect to a MySQL server.
• LDAP Authentication:Suitable for centralized management within an existing LDAP infrastructure.
