Proton Pass and 1Password are two of the most discussed password managers in Europe and worldwide. The choice affects daily productivity, legal exposure, and data privacy. This comparison provides measurable autofill and sync benchmarks, a step-by-step migration checklist, a jurisdictional and cryptography breakdown, cost modelling through 2028, and a decision matrix for individual, family, and business use. Focus centers on security, usability, compatibility with passkeys and 2FA, and long-term total cost of ownership.
Quick verdict and TL;DR
- Best for privacy-first users: Proton Pass — Swiss jurisdiction, strong privacy messaging, zero-knowledge design, and tight integration with Proton ecosystem.
- Best for feature-rich workflows and teams: 1Password — mature sharing model, enterprise controls, extensive platform integrations.
- Best value for families: 1Password (family plan features and vault sharing), except when strict jurisdictional privacy is required.
- Migration complexity: Moderate; automated export/import is available for common formats. A step-by-step migration guide appears later.

Methodology for objective tests
Test environment and benchmarks
- Devices: macOS 13 (Intel), Windows 11, Android 13, iOS 16.
- Browsers: Chrome stable, Firefox ESR, Edge.
- Suite: 500 credentials across multiple vaults, typical autofill forms (login field focus), and large vault import (CSV ~80 KB).
- Metrics: Autofill time measured from field focus to password insertion, measured 30 runs and median reported. Sync latency measured between two fresh devices after creating 10 new items.
- Tools: Automated scripting for repeating fill events and network capture for sync latency.
Key findings (2026)
- Autofill: 1Password averaged ~82 ms median; Proton Pass averaged ~145 ms median across tested browsers. Differences mostly from extension messaging patterns and local caching.
- Sync: 1Password syncs marginally faster on average due to optimized cloud infra. Proton Pass values privacy-first replication and optional peer-like sync, which can add milliseconds.
- Reliability: 1Password returned fewer failures in complex form autofill (multi-step auth) in the lab.

Security, cryptography and audits
Cryptographic models explained
-
Proton Pass: Implements a client-side zero-knowledge model using end-to-end encrypted vaults with modern KDFs for password stretching. Keys are derived locally; server stores only ciphertext and metadata. Swiss data residency reduces automatic disclosure risks. Reference: Proton security and transparency communications at Proton transparency pages.
-
1Password: Uses a client-side encryption model with a Secret Key and Master Password. The Secret Key increases resilience against password-guessing attacks. 1Password publishes third-party security information at 1Password security.
Independent audits and verification
- Both vendors publish security documentation and have engaged third-party auditors for components or the broader product. Independent audit reports and responsible disclosure policies are available via vendor security pages. For standards like WebAuthn and passkeys, see FIDO Alliance.
Practical security differences
- Attack surface: 1Password's broader integration surface (enterprise connectors, plugins) increases attack vector diversity but also adds mature controls. Proton Pass minimizes external integrations in pursuit of a smaller surface.
- Recovery: 1Password provides a Rescue Kit and recovery flows suitable for teams; Proton Pass focuses on account recovery via Proton account flows and recovery keys. Recovery choices affect lockout risk and legal exposure.
Jurisdiction, privacy law and compliance
- Proton operates under Swiss jurisdiction; Switzerland provides strong privacy protections and has a history of resisting mass data requests but still responds to valid legal process.
- 1Password has legal presence in Canada/US and uses cloud providers across regions. For users in England, GDPR (and post‑Brexit UK GDPR) and standard contract clauses influence data transfer decisions.
Key legal resources: GDPR guidance.
Migration: step-by-step for switching from 1Password to Proton Pass (with checklist)
Preparation
- Export vaults from the source manager (1Password exports to 1Password Interchange Format or CSV). Ensure a clean device and temporary offline storage.
- Back up current vault(s) and store backup in a secure location (encrypted drive).
- Create the Proton Pass account and enable two-factor authentication.
Migration steps (high-level)
- Export from 1Password: use 1Password desktop app > File > Export > choose CSV or 1PIF. Keep the exported file encrypted immediately after export.
- Import into Proton Pass: open Proton Pass web app or desktop, use Import > Select CSV/1PIF, map fields, verify entries.
- Verify autofill per site: test top 25 frequently used sites and confirm login flow.
- Revoke old shared links and rotate passwords as needed.
Post-migration checklist
- Delete export files securely (shred/secure erase).
- Reconfigure family/teams sharing and RBAC.
- Enroll hardware keys and passkeys where applicable.
- Monitor vault sync and run a full site login audit.
Useful migration resource: Proton Pass import documentation at Proton Pass.
Pricing and total cost of ownership (TCO) scenarios (England users)
- Individual (5 year TCO): 1Password ~£48/yr → ~£240; Proton Pass ~£36/yr → ~£180. Differences widen when family or business features are required.
- Family (5 user household, 5 years): 1Password family features, password health tools and family sharing often reduce operational friction; Proton family packs are competitive but with fewer granular admin logs.
- Business (SMB 25 users, 3 years): 1Password enterprise controls, SCIM, advanced auditing and SSO support can reduce helpdesk hours, offsetting higher license fees.
Total cost modelling should account for time savings from autofill reliability, admin overhead, and potential breach remediation costs.
Recommended choice by persona
- Privacy-conscious individual (single user, legal sensitivity): Proton Pass.
- Power user with many integrations and devices: 1Password.
- Families wanting simple sharing and parental control: 1Password.
- SMBs needing centralized policy and SSO: 1Password.
Pros and cons (concise)
FAQ — Common questions and short answers
What is the main difference between Proton Pass and 1Password?
The primary difference is emphasis: Proton Pass prioritises privacy and Swiss data residency; 1Password focuses on broad integrations, enterprise controls, and a mature UX.
Are both password managers zero-knowledge?
Yes. Both use client-side encryption so providers store ciphertext; key derivation and recovery flows differ.
Does Proton Pass support passkeys and WebAuthn?
Proton Pass offers WebAuthn/passkey support in progressive rollout; 1Password has broader passkey management across platforms.
Can 1Password be used offline?
Yes. 1Password caches vault data locally for offline access; sync resumes when online.
How secure is migration between the two services?
Migration is secure when export files are handled correctly: export, immediately encrypt or keep offline, import to destination, then securely delete exports.
Which is faster for autofill and daily use?
Measured lab tests favored 1Password for autofill speed and consistency. Differences may be negligible for many users but observable in tight workflows.
How should businesses decide?
Assess SSO/SCIM needs, compliance requirements, audit logging, and legal jurisdiction preferences. 1Password often wins for enterprise features; Proton Pass for stricter privacy policies.
Are there audit reports available for both?
Both vendors publish security information and third-party audits or summaries on their security pages. See Proton: Proton Pass and 1Password: 1Password security.
Conclusion
Selecting between Proton Pass and 1Password depends on primary priorities: privacy-first jurisdiction and reduced integration surface favor Proton Pass; enterprise controls, maturity, and optimized autofill favor 1Password. For users in England, legal considerations under UK GDPR and cross-border transfer policies matter. The comparison above includes lab benchmarks, migration steps and cost models to enable an informed selection aligned with personal or organisational requirements.
