Biggest opportunity: Swap “login”, “security” and “simple” for “simple login”, “rename login” and “front end login”. “login” isn't earning its slot: you're not in the first 24 results for its own search. “simple login” sits at #7 untagged, close enough for a declared tag to move it up. “security” isn't earning its slot: you're not in the first 24 results for its own search. “rename login” sits at #13 untagged, close enough for a declared tag to move it up. “simple” isn't earning its slot: you're not in the first 24 results for its own search. “front end login” sits at #18 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

How it's measured →13%
of downloads still active
At least 10K of 79.7K lifetime downloads are still running, above its category: the median Login & Users plugin keeps 0.7%, across 1,477 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.
This plugin shipped 1 release in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.

What to do about it
- Swap “login”, “security” and “simple” for “simple login”, “rename login” and “front end login”. “login” isn't earning its slot: you're not in the first 24 results for its own search. “simple login” sits at #7 untagged, close enough for a declared tag to move it up. “security” isn't earning its slot: you're not in the first 24 results for its own search. “rename login” sits at #13 untagged, close enough for a declared tag to move it up. “simple” isn't earning its slot: you're not in the first 24 results for its own search. “front end login” sits at #18 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- One page off on “captcha”. #14 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.

It does look like nice and simple solution, but it doesn’t work and wont login sometimes, or permanently for no reason.

Install and a simple captcha will be displayed in your login. The mass of login attempts by spam robots could easily be reduced with the plugin.The plugin is not compatible with other plugins such as a login for the user login.I was able to massively reduce spam attempts by using it. Thank you for the great work!
Read on wp.org ↗ - ★★★★★ DawnK3.9y ago
Worked fine at first, but then it ended up locking us out of the site. Entering correct password and the 3 digit code, would say invalid login attempt. Do the Forgot password, change password, and try to login agtain, and it would say invalid login. Had to disable the plugin in order to get access to the site again. Just my experience.

Does add a nice looking simple login code on the login screen. That’s it. Works as it should. No upselling, no pro-version, just fullfilling this one usecase. Love it.
