Biggest opportunity: Swap “brute force” for “google recaptcha”. “brute force” isn't earning its slot: you're not in the first 24 results for its own search. “google recaptcha” sits at #22 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

of downloads still active
At least 300 of 17.1K lifetime downloads are still running, above its category: the median Login & Users plugin keeps 0.7%, across 1,481 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.
