All 5 Proton Pass alternatives
Compared: open-source alternatives to Proton Pass
| Alternative | Best for | Standout | Biggest weakness | Learning curve | Price |
|---|---|---|---|---|---|
| Proton Passreference | individuals and small teams who want a zero-knowledge, open-source password manager with unlimited free logins and built-in email alias masking | Unlimited hide-my-email aliases (10 free, unlimited on Pass Plus) let a user mask their real email address per signup without a separate aliasing service. | The free plan caps hide-my-email aliases at 10 and lacks the built-in 2FA authenticator and dark web monitoring bundled into Pass Plus; like the rest of Proton's product line, getting the best per-dollar value requires bundling into the pricier Proton Unlimited plan rather than buying Pass alone. | Low | Free tier · paid from $1.99/mo |
| Bitwarden | individuals and teams who want an open-source, independently audited password manager they can self-host, at roughly half the price of 1Password or Dashlane | Fully open-source client and server code (GPL-3.0), independently audited, with an official self-hosting option and a community-maintained lightweight server (Vaultwarden) for running your own vault infrastructure. | The official self-hosted server carries a mixed license (GPL-3.0 core plus a Bitwarden-specific license for some enterprise features), and the interface is generally considered less polished than 1Password's, with fewer built-in extras like a bundled VPN. | Low | Free tier · paid from $1.65/mo |
Proton Pass
Bitwarden1.Bitwarden — best Proton Pass alternative for individuals and teams who want an open-source, independently audited password manager they can self-host, at roughly half the price of 1Password or Dashlane
Bitwarden is the best Proton Pass alternative for individuals and teams who want an open-source, independently audited password manager they can self-host, at roughly half the price of premium competitors. Bitwarden's Free tier covers unlimited passwords and devices with no time limit, a broader baseline than Proton Pass's own free tier, which caps hide-my-email aliases at 10, and Bitwarden's client code is published on GitHub under GPL-3.0 and independently audited, the same open-source license family as Proton Pass's own GPL-3.0 clients. Bitwarden holds a 4.7/5 rating from 216 Capterra reviews, well above Proton Pass's 4.9/5 from just 7 reviews, and its Premium tier costs $1.65/month billed annually, undercutting Proton Pass's own Pass Plus at $1.99/month. Bitwarden also offers an official self-hosting option plus a community-maintained lightweight server (Vaultwarden), giving users a self-hosted path that Proton Pass's cloud-only architecture doesn't provide. Proton Pass is still the better choice for anyone who specifically wants built-in email alias masking: Bitwarden's free tier excludes the integrated authenticator and file attachments, which require upgrading to Premium, and Bitwarden has no hide-my-email aliasing feature comparable to Proton Pass's 10 free aliases (unlimited on Pass Plus).
