  • A Good Login Plugin for WP

    I use Wordfence on my websites for essential security protection. Sure, the 2FA method is available for free, and is plenty good for most.However, I have been fascinated with log-in prompts recently, and it saves so much time with the websites that support it. So, I thought, why not add it to my WordPress site? And, in my journey to explore, I found Duo Universal. It's entirely free for up to 10 users - meaning, 10 WordPress applications, (don't get confused when it asks to create a “Trial account”). Unfortunately, the passkeys functionality is only applicable to the devices you created it in during the trial period. While you can use existing passkeys on the OS you created it in, you cannot create new ones after the trial period ends.Wish the pricing plan was geared towards individuals, but the premium edition needs you to purchase a subscription for 10 users at once, at the very least :/Moreover, you get to customize your branded logo + background for free. I have tested the plugin on two of my websites (WordPress 6.5.2) with different combination of plugins that include: Wordfence, SEOPress, RankMath, Really Simple SSL, Akismet, Malcare, Updraft Backups, and LightSpeed Cachep.s: I hope more people rate it, and the information for the plugin is updated to "Tested with latest WordPress version"
