Comparison
Passbox vs Proton Pass
Proton Pass and Passbox both come from Europe and both encrypt end to end. The difference: Passbox's server is open source too, and you can run it yourself.
Proton Pass is polished and has a free plan, email aliases and custom item types. Passbox is fully open source including the server, can be self-hosted with every feature and protects accounts with a Secret Key and OPAQUE sign-in.
Where Passbox is ahead
- Open-source server, not only open-source apps
- Self-hosting with every feature, free
- Secret Key as a second secret
- OPAQUE sign-in and post-quantum sealing for sharing
- €10 a year for a family of any size, instead of $59.88 for 6 people
- €30 instead of $53.88 per member per year with SSO
Where Proton Pass is ahead today
- A free plan for one person
- Its own email aliases
- Custom item types
- Passkeys on the phone, extensions for every browser
