Auto-fill passwords on every website.
The Claspt browser extension fills your passwords on every login form. Auto-fill, generate strong passwords, store identities and credit cards — without leaving the page.
Requires the Claspt desktop app. Free on all plans.
Set up in 3 steps
From install to auto-fill in under two minutes.
Install the extension
Get it from the Chrome Web Store. Works on Chrome, Edge, Brave, and Arc — any Chromium-based browser.
Enable the browser connection
In the Claspt desktop app, go to Settings → Integrations → Browser Extension → Enable. Copy the token displayed.
Connect the extension
Click the Claspt extension icon → Settings → Paste the token → Test Connection. You're ready to auto-fill.
Everything you need in the browser
Nine features that bring your passwords — and credential management — 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.
Edit, rename, move — inline
The popup is no longer just a "fill" surface. Edit username, password, TOTP, URL and custom fields. Rename labels, move to a different folder (with "+ New folder" inline), or delete — all without opening the desktop app.
Password rotation auto-detect
Fill a credential, submit a form with a different password, and the save bar offers "Update password for X". One click rotates only the password — notes, TOTP, and custom fields stay intact.
Reused-password warning
A per-row badge plus a banner with the total count when the same password is used on more than one login. Hashing happens locally with the Web Crypto API — passwords never leave your device.
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.
