Chrome Extension · Team password and passkey manager

Coauth runs in desktop Chrome. Open this page on your computer to install it.
No account for your first 3 passwords. Sharing needs a free account.
Chrome will say Coauth can read and change data on all websites. It needs that to fill and save passwords on the sites you log into; it reads only login fields.

The Problem
Shared logins are a mess.
Teams share accounts, a shared inbox, an admin panel, a vendor dashboard, but passwords get pasted into chat, and a passkey usually sits in one person's account, out of the team's reach. Coauth gives the whole team one encrypted vault to use them from.
How It Works
Save it, share it, sign in.
Share with a teammate
Open a login, choose share, and type their email. They get a link, Coauth makes the team for you, and the login is encrypted for each member.
Everyone signs in
Teammates autofill the shared password or use the shared passkey from their own browser. Nothing gets pasted into chat.

Features
Made for shared logins, not solo vaults.
01
Passwords and passkeys, one vault
Save logins as you sign in, autofill them on your next visit, and generate strong passwords. Passkeys too, created through Coauth so they can be shared.
02
Built for sharing
Share any login, a password or a passkey, with a teammate by email. They get a link, Coauth sets up the team, and everyone signs in from their own browser. Change a shared password once and every teammate gets the new one.
03
Removing someone re-keys the team
Remove a member and the team key rotates, so they cannot read anything shared from then on. Anyone who saw a password could have copied it, so change that password too.
04
Zero-knowledge
Your vault opens with your vault password, Windows Hello or Touch ID if you add it, or a recovery key only you hold. Passwords, passkey keys and note text are encrypted on your device (libsodium) before they sync, and the server never holds a key that can open them.
05
Nothing to pass around
No password pasted into a chat thread. No shared spreadsheet of logins. The login travels encrypted, and only to the people you choose.
06
Autofill where you work
Click the Coauth suggestion on a login field and it fills your username and password. Passkeys work on any site that supports them.

Straight Talk
What Coauth is, and is not.
Coauth can only share passkeys it creates: it cannot import one saved in iCloud Keychain, Google Password Manager, Windows Hello or a security key, so you add a new one through Coauth (which passkeys can be shared, and how). Only one passkey extension runs at a time, so Coauth has a one-click Pause for when you need your device's own passkeys. Teammates can view and copy a password you share with them, so when someone leaves, remove them and change the password. And your vault opens only with your vault password, your device unlock if you add one, or your recovery key: Coauth's servers never hold a key that can open it.
Who builds Coauth

FAQ
Common questions.
Is it a password manager?
Yes. Coauth saves, autofills and generates passwords, and stores passkeys. What sets it apart is sharing: any login can go to your team, end-to-end encrypted, and removing someone rotates the team key.
What is the safest way to share a password with a team?
Through a password manager built for sharing, so the password travels encrypted and never sits in a chat or an inbox. In Coauth you share a login with a teammate by email: they get a link, the login is encrypted for their device, and they sign in with one click. Change a shared password once and every teammate gets the new one.
Can Coauth share a passkey I already have?
Not one saved somewhere else. Coauth cannot import a passkey from iCloud Keychain, Google Password Manager, Windows Hello or a security key. To share one, add a new passkey to that account through Coauth, and Coauth shares that. Passwords have no such limit.
What happens when I remove someone?
Coauth rotates the team key, so they cannot read anything shared from then on. A key change cannot make someone forget, though: team members can view and copy a shared password, so change the password itself after removing someone. Shared passkeys cannot be exported.
Do I need an account to use it?
Not to start. Install Coauth and keep up to 3 passwords and 1 passkey on that computer with no sign-up. A free account removes that limit and is needed to sync across devices or to share, and both people in a share need one. You sign in with Google or with a one-time code sent to your email.
How is it different from 1Password or Bitwarden?
Those are full password suites built for whole companies, and past their starter tiers you pay for every person. Coauth does one job, sharing logins with a team: free for up to 3 people, then one flat price however many you add. If you need company-wide password management with SSO and policies, a full suite fits better.
Is it safe to keep logins in a browser extension?
Your passwords, passkey keys and note text are encrypted on your device before they sync, so the Coauth server cannot read them. The server can read some details, such as each login's site and username, and anyone who stole the database could try to guess a weak vault password offline. That is why Coauth refuses weak vault passwords and slows every guess with Argon2id. Every night a scheduled job copies the encrypted database to storage outside Supabase, the service Coauth runs on. The security page has the full picture.
Which browsers does it work in?
Desktop Chrome. There is no phone app, and Safari and Firefox are not supported.
Does it work alongside 1Password or Proton Pass?
Only one passkey extension can be active in Chrome at a time. Coauth has a one-click Pause that hands passkeys back to another manager or to your device whenever you need it.
What does it cost?
Free for 1 team of up to 3 people, you included, and pending invites count toward the 3. Pro is $5 a month or $49 a year, flat, for unlimited teams and members, admin roles, a built-in authenticator that fills 2FA codes, and a breach check you run on demand. The founding price stays for as long as you stay subscribed. You upgrade inside Coauth: Settings, then Upgrade.
