"description": "Warning: The new default authentication plugin 'caching_sha2_password' offers more secure password hashing than previously used 'mysql_native_password' (and consequent improved client connection authentication). However, it also has compatibility implications that may affect existing MySQL installations. If your MySQL installation must serve pre-8.0 clients and you encounter compatibility issues after upgrading, the simplest way to address those issues is to reconfigure the server to revert to the previous default authentication plugin (mysql_native_password). For example, use these lines in the server option file:\n\n[mysqld]\ndefault_authentication_plugin=mysql_native_password\n\nHowever, the setting should be viewed as temporary, not as a long term or permanent solution, because it causes new accounts created with the setting in effect to forego the improved authentication security.\nIf you are using replication please take time to understand how the authentication plugin changes may impact you.",

"description": "Warning: The new default authentication plugin 'caching_sha2_password' offers more secure password hashing than previously used 'mysql_native_password' (and consequent improved client connection authentication). However, it also has compatibility implications that may affect existing MySQL installations. If your MySQL installation must serve pre-8.0 clients and you encounter compatibility issues after upgrading, the simplest way to address those issues is to reconfigure the server to revert to the previous default authentication plugin (mysql_native_password). For example, use these lines in the server option file:\n\n[mysqld]\ndefault_authentication_plugin=mysql_native_password\n\nHowever, the setting should be viewed as temporary, not as a long term or permanent solution, because it causes new accounts created with the setting in effect to forego the improved authentication security.\nIf you are using replication please take time to understand how the authentication plugin changes may impact you.",
