Authentication plugins change how someone proves they are who they claim to be: a second factor after the password, a company identity provider instead of one, or a link in an email in place of a password entirely.

Together these 10 plugins run on more than 1,145,200 active WordPress sites. Ranked from both WordPress.org orderings for "authentication", its tag listing and its search results.

How to choose a Authentication Plugin for WordPress

1
Two-factor is the highest value change
A stolen password stops being enough. For administrator accounts this matters more than almost anything else on a WordPress site.
2
Have a recovery path before you enable it
Backup codes, a second administrator, or the ability to disable the plugin over FTP. Losing a phone should not lose the site.
3
Check which roles it applies to
Requiring two-factor for administrators and editors while leaving subscribers alone is usually the right balance.
4
Single sign-on is a different problem
Connecting to a company identity provider is about central control, not personal security. The plugins that do it well are not the same ones.

Authentication Plugin comparisons: side by side

The top four against each other on installs, ratings, reviews and updates. Each measure names its own leader; there is no overall winner.

How we rank Authentication Plugins

WordPress.org publishes two orderings for "authentication" and neither is reliable alone. Its tag page for "authentication" is sorted by active installs, which lets a large plugin carrying the tag loosely sit above the ones the category is about. Its search results are sorted by relevance and carry their own noise. So a plugin is placed here by where it sits across both lists: high in each one lifts it, high in only one does not. We fetch both every day at 03:00 UTC, keep every day's snapshot, and add nothing of our own. No plugin is inserted, removed or sponsored, and each entry shows its position in both lists on its own page. Full methodology.

Kadence Security, with 700,000+ active installs reported by WordPress.org as of September 7, 2026. It ranks #9 in this list.

Which Authentication Plugin has the highest rating?

Two Factor, rated 4.8 out of 5 by 208 reviewers on WordPress.org. Only plugins with at least 50 reviews are counted, so a single 5-star review does not win.

How many Authentication Plugins are there on WordPress.org?

WordPress.org lists 263 plugins tagged "authentication" as of September 7, 2026. This page shows the top 10 in the directory's own order.

Are these Authentication Plugins free?

All 10 are free to install from WordPress.org. 1 of them are listed as commercial, meaning the developer sells a paid version or add-ons: Kadence Security.

Which two-factor method should I use?

An authenticator app generating time-based codes is the practical default: it works offline, costs nothing and resists SIM swapping in a way SMS does not. Hardware keys are stronger still and worth it for administrators of valuable sites. Email codes are the weakest, because they fall to whoever already has the mailbox.

What if I lose access to my second factor?

Backup codes, stored somewhere other than the site, are the first answer, and every plugin worth using issues them. Failing that, a second administrator account can reset yours. As a last resort, renaming the plugin folder over FTP deactivates it and restores password-only login, which is exactly why the file access to your host matters.

Authentication Plugins: the bottom line
