PassGen is a tiny, focused password generator that runs 100% on your device.
No account, no ads, no analytics, no network permission.
WHY PASSGEN
• Truly offline — the app does not declare the INTERNET permission at all.
• Cryptographic randomness via Android's SecureRandom.
• Real-time entropy meter shows how strong each password actually is.
• Batch generate up to 10 passwords in one tap.
• Optional "exclude ambiguous characters" for when you need to type by hand.
• Material Design, dark theme, no bloat.
WHAT YOU CAN DO
• Pick a length between 4 and 64 characters.
• Toggle uppercase, lowercase, digits, and symbols independently.
• Tap Copy on any password to send it to the clipboard.
• Tap Copy all to grab the whole batch at once.
• Your last-used settings are remembered between launches.
PRIVACY
PassGen collects nothing. Passwords never leave the device. Your settings are
stored in private SharedPreferences that no other app can read. You can clear
them any time from Android's app settings.
PERMISSIONS
None. The app does not request runtime permissions and does not include the
INTERNET permission.
WHO IT'S FOR
• Anyone who wants a fast, dependable password generator without lock-in.
• Developers, sysadmins, and security-conscious users who need entropy on tap.
• People who don't want a password manager, just a good password.
