ReKey

A local password health auditor for macOS. Drop in the CSVs your browsers export and it finds the reused and breached passwords, generates strong replacements, and walks you to each site’s change page. Your passwords never leave your Mac. Version 1.2 adds a free Generate tab that makes a random password or a memorable passphrase without an audit first.

Free on the Mac App Store for macOS 15 or later, with a one-time purchase to fix passwords. The GitHub build is the whole app, cleanup tool included, as a signed, notarized .dmg from GitHub Releases (opens in new tab).

Four sites in ReKey’s Findings list share the password Summer2019!, which appears in 16,241 breaches. — The Findings list groups the reused and breached passwords by site, worst first.

ReKey’s fix queue, with a new 20-character password ready for streamflix.com. — The fix queue gives each account a strong replacement and opens its change page, or the site itself when it can’t find one.
