of downloads still active

At least 300 of 7.1K lifetime downloads are still running, above its category: the median Login & Users plugin keeps 0.7%, across 1,476 plugins.

Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Login & Users plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.

Removal-risk signals

51/100

Maintenance and integrity signals that tend to precede a WordPress.org removal. Not an official status, a heads-up to act.

  • Long abandoned. No update in 7+ years — the top precursor to removal once a vulnerability is found.
  • No tested-up-to version. The listing declares no "Tested up to" version.

    On some WP sites it works, but on others it doesn’t work. Must be a ‘conflict’ somewhere. Too bad there is no logging to see where it goes wrong. As soon as I rename the woo-yubi folder, to disable the plugin, I can login again.

    at first i wasnt’ sure who i can trust. i mean this plugin is written by a stranger, not yubikey. So i got my unique api key from yubikey.co and installed it. Entered it into the plugin. enabled the user from user/profile, plugged in my key to generate a key, saved, logged out and logged back in and it worked. I tried any NON enabled user and of course did not enter a key via my key and got in. So here’s my test that this plugin author is actually communicating with yubikey.co, I changed just one letter in my api id and tried logging in, and i could NOT. Soo… this tells me that it’s trying to communicate with yubi apparently to authenticate, otherwise it would not know. Alternately, i could have deleted my api key from yubikey.co to test. regardless, it works seamlessly. I’m using WP 5.8.6

    It appeared on the login screen but then caused login to fail “Incorrect Username or Password”. I had to delete the plugin folder from the server to get in to my WP admin. I’m new to Yubikey so the error could be in how I use my new keys (though I added them both to the WP admin profile and the Yubikey API to the plugin settings page). I love the idea – wish it would work for me.

    Thanks for an amazing plugin. Hopefully the maintainer is looking and will update things to show they are tested as working with WP 5.4, since it does.

    So nice to have the possibility of adding an extra layer of security to WordPress admin panel. Plugins is working perfect with version 5.3.2. I encountered some semantic issues, thus, using in WordPress “Yubico API ID and Yubico API key” vs “Client ID and Secret Key” on Yubico’s site, not important.

    Exactly what I was looking for. Just install, activate it and get/insert an API Key (which can be obtained in seconds). Subsequently every user can manage the Yubikey-Settings right in the profile. Nothing more, Nothing less.

    WP 5. and a Fairly old Yubikey. Installation and API activation worked without hassle but when entering the OTP on the login page it just fails to grant access. No obvious errors. I have no time to trouble shoot, so will look for an alternative 2fa.

    I love WordPress for it’s simplicity to use and it’s rich eco-system to achieve complex challenges, but always felt that a simple username and password combination was not enough to elevate the security of WordPress. Now with this Yubikey-Plugin, I’m finally able to add an additional factor to safeguard against unauthorised access. Many thanks to Adam Lyons for making this plugin available. It’s really easy to set up and to activate 2FA per user account. I also notified Yubico to update their WordPress plugin link to this plugin.
