Help What is LesS/KEY & how it works click to open
LesS/KEY is a password manager that stores no passwords. It re-generates each one on demand from your single master password plus the name of the account. The same name + master always produce the same password — so there is nothing secret to leak, sync, or back up, and you only ever remember one phrase.
Quick password
Type an account name and your master phrase — the password appears instantly, masked. Click it to reveal, or press Copy. Store remembers the name (never the password) in this browser.
Console
The full command line — type help for every command. Your list of
names lives only in this browser (localStorage); use Export /
Import to move it (e.g. to and from a Notion page).
Naming rules
After a name you can add a length and a mode — R words,
C camel, H hex, B base64, D
digits (U… = upper). E.g. github 20R.
Runs the real hel engine compiled to WebAssembly — the exact same generator as the command-line tool. Nothing is ever sent to a server.
Quick password
Deterministic — the same name + master always regenerate the same password. The result updates live as you type. Nothing is stored unless you press Store.
All commands
The full hel command line — ls, add,
enc, gen, comment,
correct, help, … Your catalog persists in this
browser (localStorage). Generated passwords are masked — click to reveal.
