Description\n-----------\n\nsimple_password_check is a password validation plugin. It can check whether a password contains at least a certain number of characters of a specific type. When first installed, a password is required to be at least eight characters, and requires at least one digit, one uppercase character, one lowercase character, and one character that is neither a digit nor a letter.\n\nNote that passwords can be directly set as a hash, bypassing the password validation, if the strict_password_validation variable is OFF (it is ON by default).\n\nInstalling the Plugin\n\nAlthough the plugin's shared library is distributed with MariaDB by default, the plugin is not actually installed by MariaDB by default. There are two methods that can be used to install the plugin with MariaDB.\n\nThe first method can be used to install the plugin without restarting the server. You can install the plugin dynamically by executing INSTALL SONAME or INSTALL PLUGIN:\n\n``sql\nINSTALL SONAME 'simple_password_check';\n`\n\nThe second method can be used to tell the server to load the plugin when it starts up. The plugin can be installed this way by providing the --plugin-load or the --plugin-load-add options. This can be specified as a command-line argument to mariadbd, or it can be specified in a relevant server option group in an option file:\n\n`ini\n[mariadb]\n...\nplugin_load_add = simple_password_check\n`\n\nUninstalling the Plugin\n\nYou can uninstall the plugin dynamically by executing UNINSTALL SONAME or UNINSTALL PLUGIN:\n\n`sql\nUNINSTALL SONAME 'simple_password_check';\n``\n\nIf you installed the plugin by providing the --plugin-load or the --plugin-load-add options in a relevant server option group in an option file, then those options should be removed to prevent the plugin from being loaded the next time the server is restarted.\n\nExamples\n--------\n\nSET PASSWORD FOR 'bob'@'%.loc.gov' = PASSWORD('abc');\nERROR 1819 (HY000): Your password does not satisfy the current policy requirements\n\nURL: https://mariadb.com/docs/server/reference/plugins/password-validation-plugins/simple-password-check-plugin
