Credensy

Zero-knowledge password manager — autofill and quick vault access.

Credensy is a zero-knowledge password manager — your vault is encrypted on your own device before it ever reaches our servers. We can't read your passwords. Neither can anyone who breaches us. This extension brings your vault right into the browser: 🔐 AUTOFILL, THE WAY IT SHOULD WORK See a saved login the moment you land on the page — one click fills both username and password. Works on standard forms and single-page apps alike. 📋 CAPTURE AS YOU SIGN IN Log into a new site and Credensy offers to save it — no manual entry. Change a password on a site you already saved? It offers to update the existing entry instead of creating a duplicate. 🔑 GENERATE STRONG PASSWORDS ANYWHERE Right-click any password field to drop in a fresh, cryptographically random password — no need to open the vault first. ⏱️ BUILT-IN AUTHENTICATOR Store your TOTP secrets alongside your logins and get live, auto-refreshing 2FA codes right in the popup — one less app to juggle. 🖱️ RIGHT-CLICK, FILL, DONE A native context menu for filling saved logins or generating a password, on top of the per-field icon and the popup's search. Under the hood: • AES-256-GCM envelope encryption and Argon2id key derivation — the same zero-knowledge design as the Credensy web app • Your master password and vault key never leave your device, and never touch our servers • Copied passwords and codes clear from your clipboard automatically after a short delay • Minimal permissions, no telemetry, no ad tracking, no data resale This extension covers logins and authenticator codes. For everything else in your vault — secure notes, API keys, documents, and more — open the full Credensy web app. Credensy. We built it so we can't read it.
