OFFLINE BY DESIGN · OPEN SOURCE

Passwords you don’t have to store.

acctpass regenerates a unique, strong password for every account from one encrypted local seed and a recipe only you control.

Most password tools retrieve a secret from a vault. acctpass takes a different route: it reconstructs the secret only when you need it.

One local secret.
Every account.

Regenerate,
don’t retrieve

The same versioned recipe regenerates the same result, every time.

Local by
default

No account, no sync service, and no network connection required.

Rotate without
starting over

Increment the counter to create a new password for one account.

A SMALL, EXPLAINABLE SYSTEM

From master password
to account password.

Your master password unlocks a random local seed. The seed and account recipe then flow through a deterministic, versioned process.

01

Unlock the seed

Argon2id derives the key used to decrypt your local vault.

02

Describe the account

Service, account, counter, length, and symbol preference.

03

Derive locally

HMAC-SHA256 turns the seed and recipe into deterministic bytes.

04

Copy, then forget

The result is copied for use and never added to the vault.

THE DESKTOP APP, AVAILABLE NOW

The CLI’s behavior, made approachable.

The native app uses a Rust/Tauri backend and compatibility vectors that check its password output against the Go CLI.

SECURITY, WITHOUT THE SLOGANS

Designed to be inspected, tested, and questioned.

acctpass names the exact primitives it uses and the limits it has. It does not call unaudited software “military-grade.”

A DIFFERENT TRADEOFF

Not a password manager in disguise.

TRADITIONAL MANAGER

Encrypts and retrieves saved passwords.

Best for autofill, passkeys, sharing, recovery, or sync.

ACCTPASS

Regenerates passwords from a local seed.

Best for a tiny offline tool when you accept the backup tradeoff.
