The Password Validation Component Password Validation Component Status Variables. MySQL installations that use the plugin should make the transition to using the component instead. See Section 6.4.3.3, “Transitioning to the Password Validation Component” . This  validate_password  plugin status variable is deprecated; expect it to be removed in a future version of MySQL. Use the corresponding  validate_password.dictionary_file_last_parsed status variable of the  validate_password  component instead. In MySQL 8.0, the  validate_password  plugin was reimplemented as the validate_password  component. The  validate_password  plugin is deprecated; expect it to be removed in a future version of MySQL. MySQL installations that currently use the  validate_password  plugin should make the transition to using the  validate_password  component instead. To do so, use the following procedure. The procedure installs the component before uninstalling the plugin, to avoid having a time window during which no password validation occurs. (The component and plugin can be installed simultaneously. In this case, the server attempts to use the component, falling back to the plugin if the component is unavailable.) Those settings are appropriate for the plugin, but must be modified to apply to the component. To adjust the option file, omit the  --validate-password  option (it applies only to the plugin, not the component), and modify the system variable references from no-dot names appropriate for the plugin to dotted names appropriate for the component: [mysqld] validate-password=FORCE_PLUS_PERMANENT validate_password_dictionary_file=/usr/share/dict/words validate_password_length=10 validate_password_number_count=2 [mysqld] validate_password.dictionary_file=/usr/share/dict/words validate_password.length=10 validate_password.number_count=2 INSTALL COMPONENT ’file://component_validate_password’; This  validate_password  plugin status variable is deprecated; expect it to be removed in a future version of MySQL. Use the corresponding  validate_password.dictionary_file_words_count status variable of the  validate_password  component instead. 1396 3. Adjust any references to the plugin system and status variables to refer to the corresponding component system and status variables. Suppose that previously you had configured the plugin at startup using an option file like this: 2. Test the  validate_password  component to ensure that it works as expected. If you need to set any validate_password. xxx  system variables, you can do so at runtime using  SET GLOBAL . (Any option file changes that must be made are performed in the next step.) 1. Install the  validate_password  component: Note 6.4.3.3 Transitioning to the Password Validation Component • validate_password_dictionary_file_words_count • validate_password_dictionary_file_last_parsed
