Everything you need in the browser
Six features that bring your passwords to every website.
Auto-Fill
Detects login forms automatically. Use Cmd+Shift+L to fill instantly. Works with React, Vue, Angular, and plain HTML forms.
Password Generator
Fully offline. Three modes: Password, Passphrase, and PIN. Configurable presets and a history that saves the last 50 generated passwords.
Save Bar
Auto-detects new logins as you sign up or change passwords. One-click save directly to your vault — no copy-paste required.
Identities & Credit Cards
Auto-fill personal information, addresses, and payment details on checkout forms. All stored encrypted in your vault.
Security
Built-in phishing detection warns you about suspicious domains. Clickjacking protection, auto-lock on idle, and zero cloud dependency.
Context Menu
Right-click any field to fill from your vault. Works on custom inputs and obscure form elements that auto-detection might miss.
Keyboard shortcuts
Stay in the flow. Never reach for the mouse.
On Windows/Linux, replace Cmd with Ctrl. Shortcuts are customizable in chrome://extensions/shortcuts.
