IronVault — Secure Autofill

Zero-knowledge autofill for passwords, TOTP, cards & identities. AES-256 encrypted — your master password never leaves your device.

IronVault Secure Autofill fills your passwords, two-factor codes, credit cards and identities on any website — and offers to save new logins as you sign in. It’s the browser companion to your IronVault vault (ironvault.app). WHAT IT DOES • Autofill logins — detects the sign-in form and fills your username + password in one click. • Save & update — when you sign in or change a password, IronVault offers to save or update it. • 2FA / TOTP codes — fills one-time codes into verification fields. • Cards & identities — completes checkout and address forms. • Password generator — create a strong password without leaving the page. • Search your vault — find any login from the toolbar popup. ZERO-KNOWLEDGE BY DESIGN Your vault is encrypted with AES-256-GCM. Your master password derives the encryption key locally and is never transmitted, never stored on our servers, and never leaves your device — we only ever exchange encrypted data. IronVault cannot read your passwords, and neither can anyone else. SMART, SAFE MATCHING A login saved for a site is offered on that site and its subdomains — and never on unrelated sites that merely share a hosting suffix (for example, two different project.github.io sites never share credentials). PRIVATE No tracking. No analytics of the sites you visit. No selling of data. No remote code — all logic ships in the extension and is plain, reviewable JavaScript. REQUIREMENTS A free IronVault account (sign up at ironvault.app). Works alongside your IronVault iOS and Android apps, syncing your encrypted vault across devices.
