how to choose a Proton Pass Plus alternative

Vaultwarden — a one-click install, no server to maintain.
Most proven
Vaultwarden, with 45,000 GitHub stars — the largest community of the 4, which usually means more answers when something breaks.
Works on your phone
AliasVault has a mobile app on iOS and Android.
Needs real ops to self-host
Keycloak is capable but expects someone to run a server, updates and backups. Budget for that before choosing it.
what you give up by leaving Proton Pass Plus
- Proton identity, email alias infrastructure, audits, apps, recovery, and privacy operations

why people still pay for Proton Pass Plus
People still pay for Proton Pass Plus because security products are paid for because expert review, infrastructure, and accountability matter more than recreating screens. The recurring cost buys cryptography, secure updates, key recovery, threat intelligence, relay capacity, abuse response, audits, and incident handling, not just the visible interface. If none of that applies to you, any pick above saves $35.88 a year.
