Werkzeug

Private tools: deterministic passwords, 2FA codes, calculator and clock.
New in version 0.4.4
- Werkzeug updates the existing Pass Android app using its original application ID and signing certificate, keeping its saved data.
- The app continues to appear as Werkzeug, with Pass, Auth, Calculator and Clock together.
Werkzeug holds small private tools in one app. Everything is computed on your device and nothing is tracked. It makes no network requests unless you turn on sync.

• Pass derives strong, repeatable passwords. The same site, login, master password, and settings always produce the same result, so there is no password database to back up, sync, or lose. It is LessPass-compatible, with configurable length, counter, character classes and excluded characters, and an optional master password kept behind device authentication.
• Auth shows two-factor sign-in codes (TOTP with SHA-1, SHA-256 or SHA-512). Add accounts by secret key or from otpauth links, Google Authenticator export links, unencrypted Aegis exports or Ente Auth's plain-text export. Rename an account or note the websites where it signs in. Copied codes are cleared from the clipboard after 30 seconds. Optional sync keeps them on all your devices, encrypted on the device so the server never sees them.
• Calculator handles everyday arithmetic with brackets, powers and percent, and has a Scientific mode with trigonometry, logarithms, roots, factorials, π and e.
• Clock shows the local time and date and has a stopwatch.

A profile with your name and picture sets the appearance every tool shares.

Every tool works without a Daochi account. In Profile → Sync you can choose your own node before connecting an account, or pause sync without forgetting your keys and local records. Sync stays off after restarting until you turn it on again.

Pass is an independent implementation of the LessPass algorithm. Compatibility does not imply endorsement by or affiliation with the LessPass project.
