As of 28 Oct 2026, the panel rates Bitwarden 3.5/5 and Proton Pass 3/5 in Password Management. Weighted by what each judge cares about, 6 of the 6 judges pick Bitwarden and 0 pick Proton Pass. Bitwarden scores higher on 5 of 7 criteria (Hosting choice, offline access & export, Audit logs, policies & reporting, Pricing transparency, plus 2 more). Proton Pass scores higher on 1 of 7 criteria (European sovereignty). Provenance — Bitwarden: Rest of world, United States; Proton Pass: UK / wider Europe. Ratings are the AI panel’s opinion, formed from public evidence: how scores are made.
The short answer
Five of the seven criteria lean Bitwarden: audit and policy (6 judges to 0, means 7.7 vs 6.0), deployment and portability (6–0, 7.0 vs 4.0), pricing transparency, identity integration (4–0 with two ties) and sharing and access control (3–0 with three ties). Proton Pass is ahead on sovereignty — means 4.3 vs 3.7, three judges leaning its way, three tying, 0 leaning Bitwarden — with its attributes listing a CH legal entity and US CLOUD Act subprocessor exposure against Bitwarden's US legal entity and US default for data residency. Security architecture splits the bench: means tie at 6.8, one judge leaning each way, four ties. The five weighted totals the table lists put Bitwarden ahead (CISO 6.6 vs 6.2; skeptic 6.2 vs 5.6). Because the lean differs by criterion and judge, no overall winner is declared here.
Choose Bitwarden if
- You need to self-host your password manager — deployment and portability leans Bitwarden 6 judges to 0 (means 7.0 vs 4.0); the verdict documents self-hosting for Windows, Linux, Docker and Kubernetes, while we found no public information on Proton Pass self-hosting.
- Your audit program depends on named SIEM integrations and long log retention — audit and policy leans Bitwarden 6–0 (means 7.7 vs 6.0), citing over 60 event types, indefinite retention and a 367-day viewable window.
- You rely on SSO over SAML 2.0 and OIDC where the identity provider never holds the decryption key — identity integration leans Bitwarden 4–0 with two ties (means 7.3 vs 6.3).
- You must budget from published per-user prices — pricing transparency leans Bitwarden 5–1, with Teams at "$4 per month / per user billed annually" and Enterprise at "$6 per month / per user billed annually" (seat minimums, add-on prices and self-hosted licensing are not shown).
- Shared-vault governance drives your rollout — sharing and access control leans Bitwarden 3–0 with three ties (means 6.7 vs 6.2).
Choose Proton Pass if
- You require a legal entity outside the United States — Proton Pass's sovereignty attribute records CH against Bitwarden's US, and sovereignty leans Proton Pass 3 judges to 0 with three ties (means 4.3 vs 3.7).
- Your data-residency standard rules out a US default — Bitwarden's sovereignty attribute records a US default for data residency, and the sovereignty means favor Proton Pass (4.3 vs 3.7).
- Your contracting chain cannot sit under Delaware incorporation and California governing law — Bitwarden's verdict describes 8bit Solutions LLC under Delaware-incorporated Bitwarden Inc. with California law; sovereignty is the one criterion leaning Proton Pass (3 judges, 0 for Bitwarden).
- You can trade self-hosting for a CH-based vendor — sovereignty leans Proton Pass (3–0 with three ties) even as deployment and portability leans Bitwarden 6–0.
