Zero-knowledge password + passkey manager for teams. Save, autofill, and share logins — end-to-end encrypted. A password + passkey manager built for teams, and it's zero-knowledge. Coauth saves your website logins, fills them in for you, generates strong passwords, and, the part nothing else does well, lets you SHARE a login (password or passkey) with a team, encrypted, so a shared account works for everyone without passing secrets around in chat. No account needed to start. Install and use it locally; create a free account (Google sign-in) only when you want to sync across your devices or share with a team. WHAT IT DOES • Save passwords as you log in, and autofill them on your next visit. Built-in strong-password generator. • Create and use passkeys on any site that supports them. Coauth is a software authenticator, so its passkeys can be shared (unlike a fingerprint passkey locked to one device). • Share any login into a team. Teammates autofill the password or use the shared passkey from their own browser, no secret ever changes hands. • Manage it all in one popup: a unified vault of passwords and passkeys, teams, roles, invites, and an activity log. WHY IT'S DIFFERENT • Purpose-built for SHARED logins, with roles, email invites, and REAL revocation: remove a member and the team key rotates, so their access actually ends. • Zero-knowledge. You unlock your vault with your device passkey (or a recovery key only you hold). Everything is end-to-end encrypted with audited cryptography before it syncs, so the server stores only ciphertext and can never read your passwords or passkeys. • Nothing to pass around. No exported password in a chat, no shared spreadsheet of logins. HOW IT WORKS 1. Install and secure your vault with this device's unlock (Windows Hello / Touch ID) or a one-time recovery key. No account needed to start. 2. Log in on a site and Coauth offers to save it. Or add one manually with the generator. 3. Next visit, click the Coauth suggestion to autofill. 4. Sign in with Google when you want to sync across your devices or share a login with a team. GOOD TO KNOW • No account needed to start. A free account unlocks unlimited saving, sync across your devices, and team sharing. • Coauth can only share passkeys it created. A passkey already registered with your fingerprint or a security key can't be exported (that's how passkeys work), add a new one through Coauth to share it. • One passkey extension can be active at a time. Coauth has a one-click Pause to hand control back when you need it.
