I am currently using a plugin called Very Simple Password which requires viewers to input a password to access the site. I currently have Yoast installed to fix my meta tags, however whenever I post the link on my social media (especially Facebook), the meta tags I've set there are not reflecting. Instead, it's reflecting the properties from the password-protected homepage generated by Very Simple Password. I've scraped using the Facebook debugger tool, but even the Open Graph properties did not reflect.
Is there a way for me to add meta tags to the password-protected homepage? I've checked the plugin's php files and when I've added the meta tags manually, I keep getting an error.
