About Pass Builder
Pass Builder creates strong, random passwords in one click, right from your Chrome toolbar.
Click the key icon (or press Alt+Shift+P) and a fresh password is ready. Adjust the length, pick your character types, copy, and paste. That's it.
FEATURES
- Compact dropdown that opens right under the toolbar icon
- Password length from 8 to 64 characters
- Any mix of lowercase, uppercase, numbers and symbols, with at least one of every type you choose in each password
- Instant strength meter: Weak, Fair, Good or Strong
- One-click copy to clipboard
- Remembers your preferred length and character types
- Keyboard shortcut (Alt+Shift+P), changeable in Chrome's shortcut settings
- Fully usable with the keyboard alone
TRULY RANDOM
Every password comes from your browser's built-in cryptographic random number generator (the Web Crypto API), using an unbiased selection method so no character is ever favored over another.
PRIVATE BY DESIGN
- Runs entirely on your device. Pass Builder makes no network requests.
- Generated passwords are never saved, logged or sent anywhere.
- The only thing stored is your preferred length and character types, kept in Chrome on this computer and never synced. Clear it anytime with "Reset to defaults" in Settings.
- No accounts, no ads, no tracking, no analytics.
- Asks for a single permission ("storage"), used only to remember those preferences.
GETTING STARTED
1. Pin Pass Builder: click the puzzle-piece icon in the toolbar, then the pin next to Pass Builder.
2. Click the key icon or press Alt+Shift+P.
3. Copy your new password and paste it wherever you need it.
