Hey @sreejan1508,
No, Wordfence does not offer that option altough many other plugins do (e.g., iThemes Security, Perfmatters, etc.). We use Perfmatters.
It would be nice if Wordfence offered that option and allowed their customers decide what’s best for them.
Special Note: Keep in mind that if you obscure your login URL, there may be login links in your website (generated by other plugins) that could be affected by the change. In these cases, the plugin developer (not Wordfence) may have to issue a special filter to ensure the affected login links work as intended. Case in hand is the plugin, WPDiscuz, which uses WordPress’ standard login URL.
Hope this helps a bit.
Best wishes ??
