Coauth vs Bitwarden: a free Bitwarden alternative for small teams.
Bitwarden is a great password manager. This is not a takedown. It answers one narrow question: what is the lightest way to share a few logins, passwords or passkeys, with a small team, without rolling out a suite or paying for every seat?
For sharing logins with a small team, here is the honest difference.
| Coauth | Bitwarden | |
|---|---|---|
| Free to share a login with a team | Yes, up to 3 people | Between 2 people; teams pay $4 per user |
| Start without an account (sharing needs a free account) | Yes | No |
| Single shared login, no org to set up | Yes | No, an organization and collections |
| Removing a member rotates the key | Yes | Removes access |
| Built for sharing logins with a team | Yes | General purpose |
| Zero-knowledge encryption | Yes | Yes |
| Self-host and full org vaults | No | Yes |
Bitwarden details from public information; prices from its own pricing page, checked October 15, 2026. Coauth is free for a team of three, then one flat price.

Coauth vs Bitwarden, answered.
Is Coauth a replacement for Bitwarden?
No. Bitwarden is a full open-source password suite you can even self-host. Coauth does one thing: share logins with a team, free for up to three people. For company-wide management, Bitwarden is excellent.
Can I not just share the login in Bitwarden for free?
Between two people, yes: Bitwarden's free plan lets you share with one other user through a free two-person organization. Sharing with more people means a paid Teams or Enterprise organization, billed per user. Coauth shares a login, password or passkey, with up to 3 people for free, then $5 a month flat.
Can Coauth share a passkey I already saved in Bitwarden?
Not directly: Coauth cannot import a passkey saved in Bitwarden. To share access through Coauth, add a new passkey to that account through Coauth, which seals it to each teammate. Many sites let an account have more than one passkey.
Which should I pick?
For a few logins shared with a small team, free for three and flat after that, with a revoke that rotates the key, Coauth fits. For a full organization vault on a budget, Bitwarden fits.
