In a group I'm in, someone mentioned "security plugin." I am not sure what that is, and I'm not sure if any of mine qualify as that, and also not sure if I should add another plugin to my site... What I have that I was thinking might fall into this category are these: Akismet Limit Login Attempts Updraft Plus for backups... So... I thought I'd ask y'all what a security plugin is and if you think I need to add yet another plugin to my website... ? Thank you!
