Do you get irritated by numerous password reset mails triggered by spammers or bots trying to spam your id? If you have, you can disable password reset option completely to safeguard your id a bit more and save you from those irritating mails. Justin Tadlock has written a neat little plugin for this purpose: Prevent Password Reset. Once you enable this plugin, you can disable the password reset option for any user of your blog by enabling a simple option from the user’s profile page.
Note: If you end up forgetting the password, you will need to rename/remove the plugin directory to deactivate the plugin or will need to change the password via sql.
