JHFvcKey is a simple, offline-capable password generator that helps create stronger passwords using a consistent personal format.
It runs entirely in the browser, stores nothing, and works even without internet once installed.
JHFvcKey follows this structure:
JHFvX + Site Tag + Your Password + Random Numbers
Example: JHFv2GHMySecret!483
- JHFvX → Version (v1, v2, etc.)
- Site Tag → Short label like GH (GitHub), GG (Google), DC (Discord)
- Your Password → The part only you know
- Random Numbers → Added automatically for extra security
- Version selector (JHFv1, JHFv2)
- Site tags for different services
- Show / hide password toggle
- Password strength meter (Weak / Medium / Strong)
- Adjustable random number length
- One-click copy to clipboard
- Works offline (PWA)
- Installable like an app (iOS, Android, Desktop)
- No tracking, no storage, no backend
- Passwords are never saved
- Nothing is sent to any server
- No analytics
- No accounts
- Everything runs locally on your device
Think of it like a calculator — it helps you create something, but it doesn’t remember it.
