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.

Stay in the flow. Never reach for the mouse.
