Coauth vs Proton Pass for a shared team login.
Proton Pass is a great password manager. This is not a takedown. It answers one narrow question that got urgent in 2026: what is the lightest way to share a single Salesforce login now that phishing-resistant MFA broke the old shared-authenticator trick?
For one shared login, here is the honest difference.
| Coauth | Proton Pass | |
|---|---|---|
| Free to share a login with a team | Yes | Limited, paid for more |
| Use without an 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 the Salesforce shared-login MFA case | Yes | General purpose |
| Zero-knowledge encryption | Yes | Yes |
| Full privacy suite (Mail, VPN, Drive) | No | Yes |
Proton Pass details from public information. Coauth is free for a team of three, then one flat price; Proton Pass is a full suite.
Pick the right tool for the job.
Choose Coauth when
- ›You only need to share one login (a Salesforce service account), not a shared vault.
- ›You want it free, with no Proton account and nothing to configure.
- ›You want removing someone to rotate the key so their copy can no longer decrypt.
Choose Proton Pass when
- ›You want a privacy-first suite that also gives you Proton Mail, VPN, and Drive.
- ›You want shared vaults across an organization with Proton account management.
- ›You want mature mobile and desktop apps backed by Proton.
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 a single login with a team, for free with no account to start. For a privacy suite and org vaults, Proton fits.
Can I not just share a vault in Proton Pass for free?
Proton Pass has a free tier, but vault sharing across a team is limited and scales on a paid plan. Coauth shares one login, password or passkey, for free with no vault to configure.
Can Coauth share a passkey I already saved in Proton Pass?
No tool can export an existing passkey, by design. To share one, add a new passkey to that account through Coauth, which seals it to each teammate.
Which should I pick for a shared Salesforce login?
For one shared service account behind the new MFA, shared cheaply with a clean revoke, Coauth fits. For a privacy suite with shared vaults, Proton Pass fits.
