Coauth vs Proton Pass for sharing logins with a small team.
Proton Pass 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 | Proton Pass | |
|---|---|---|
| Free to share a login with a team | Yes, up to 3 people | Yes, a vault with 2 others; 10 on paid plans |
| Start without an account (sharing needs a free account) | Yes | No, needs a Proton account |
| Single shared login, no vault to set up | Yes | No, shared vaults |
| Removing a member rotates the key | Yes | Removes access |
| Built for sharing logins with a team | Yes | General purpose |
| Zero-knowledge encryption | Yes | Yes |
| Full privacy suite (Mail, VPN, Drive) | No | Yes |

Coauth vs Proton Pass, answered.
Is Coauth a replacement for Proton Pass?
No. Proton Pass is part of a full privacy suite with shared vaults. Coauth does one thing: share logins with a team, free for up to three people. For a privacy suite and org vaults, Proton fits.
Can I not just share a vault in Proton Pass for free?
Yes, with up to 2 other people: Proton Pass Free shares a vault with 2 others, and its paid plans raise that to 10. Coauth's free plan also covers 3 people, and Pro is $5 a month flat for unlimited teams and members. Both need an account for everyone who shares.
Can Coauth share a passkey I already saved in Proton Pass?
Not directly: Coauth cannot import a passkey saved in Proton Pass. 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, one flat price at any size, with a revoke that rotates the key, Coauth fits. For a privacy suite with shared vaults, Proton Pass fits.
