1key4all.com - One key for everything
Keep your login details neat and secure - no email registration, no password chaos, and even no personal details.
What 1key4all.com does for you
All passwords in one place
All passwords, PIN codes, and other access data in one spot.
Find fast instead of searching forever.
Strong passwords — made easy
The generator suggests secure passwords. Unsafe ones are clearly marked.
Stay on track without stress
Reminders to update (e.g., every 3 months). Notices when you reuse a password.
Order with tags
Group everything (Home, Work, Wi-Fi, Kids, Grandma, Grandpa, School, WebApp, etc.) and filter with one click.
Show & copy safely
Passwords are hidden first (handy if someone's looking at your screen). Use “Copy to clipboard” to paste cleanly where needed.
How sign-in works
You don’t need an e-mail address or any other personal data.
You choose an alias (e.g., “QuietRiver-2025”, or just create one using the Alias Generator) and a master password.
Alias + master password = your key code
From alias and master password, a one-time key code is calculated at login.
End-to-end protected. A 256-bit key (derived with Argon2id/PBKDF2) and AES-256-GCM encryption keep your data safe. Your key is never stored at the server — the server only ever sees encrypted data.
What’s on the server?
A fingerprint of your alias (one-way — nobody can reverse it to the alias/masterpassworf).
Your encrypted vault (your passwords). Without the key code it stays unreadable.
The Lock That Fits One Key
At login, the key code is recalculated from alias + master password.
If both match exactly, the code fits and the vault opens. If anything differs, a different code is created —
the vault stays closed.
In short: only the correct combo of alias and master password opens your data. No
one else can. Even if someone copied the server, they would see only unreadable encryption.
Good to know (honest & transparent)
We don’t store personal recovery data.
If you forget alias or master password, we can’t restore access — by design, for maximum security.
In that
case, you can only create a new account.
So: keep alias and master password in a safe place.
