Kardix uses memory-hard Argon2id and separate derivation domains to recreate the same username and password whenever you return.
01
Enter your phrase
Choose a long phrase you can remember. Kardix never sends it to a server.
02
Add an optional PIN
A PIN creates a different result while keeping the experience fast and simple.
03
Recreate your login
Use the exact same inputs later and Kardix returns the same generated details.
Private by design
Nothing leaves your browser.
The generator runs locally on your device. Kardix does not require an account, cloud vault, or password database.
No registration or login
No stored passphrases or PINs
Memory-hard Argon2id derivation
No generated credentials uploaded
No cloud synchronization required
How it works
The same private inputs recreate the same login.
Kardix combines your phrase, optional PIN, account label, and the KDX2 version locally. It does not need a stored password vault.

Kardix reduces the need for a stored vault, but it does not replace device security, service recovery, passkeys, or two-factor authentication.
