Proton Pass and Bitwarden both offer free password-manager plans with multi-device access, but they suit different workflows. Proton Pass stands out if you want hide-my-email aliases and straightforward item or link sharing. Bitwarden is a better fit to investigate if you want organization-based sharing or the option to self-host. Neither is established as the universally better or more secure choice by the available evidence.
At a glance: which service fits your needs?
| Your priority | What the available plan information says | What to check |
|---|---|---|
| Free use across devices | Proton lists unlimited logins and devices on its Free plan. Bitwarden’s plan document, marked © 2025, lists unlimited core password-manager storage and access and sync across devices. | Review each service’s current plan page for any changes to included features. |
| Email aliases in the password-manager workflow | Proton lists 10 hide-my-email aliases on Free and unlimited aliases on paid Pass plans. Proton’s comparison says Bitwarden supports aliases through third-party integrations. | Decide whether you want aliases built into the service or are content using a separate integration. |
| Sharing credentials | Proton documents vault and item sharing, as well as share links with expiration and view-count controls. Bitwarden’s plan document ties sharing to organization plans; Proton describes its model as organization- and collection-based. | Consider whether you share individual items or manage access through a shared organization. |
| Self-hosting | Bitwarden’s © 2025 plan document lists self-hosting for certain individual plans and Families organizations. Proton’s comparison says Pass does not offer self-hosting. | Choose self-hosting only if you can take responsibility for operating and maintaining the infrastructure. |
| Security comparison | Proton describes its own encryption, open-source apps, and audits. Proton’s comparison says both products are open source; the reviewed material does not establish which is more secure in practice. | Compare the security details that matter to you without treating transparency claims as proof of a head-to-head security result. |
What do the free plans include?
Proton Pass Free
Proton lists unlimited logins and devices, 10 hide-my-email aliases, and alerts for weak or reused passwords on its Free plan. These allowances make it worth considering if you want aliases alongside password storage without starting with a paid tier. See Proton Pass plan details.

Bitwarden Free
Bitwarden’s plan document marked © 2025 lists unlimited secure storage for logins, notes, cards, and identities, plus access and sync across devices. The document is useful for understanding the plan structure, but its age means you should confirm current features on Bitwarden’s official site. View Bitwarden’s plan document.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
The plans describe their free allowances differently: Proton explicitly lists unlimited logins and devices, while Bitwarden’s document specifies unlimited storage for several record types and cross-device access and sync. Compare the kinds of information you store and the current terms, rather than assuming the wording means the plans are identical.

How do paid features and sharing differ?
Proton Pass paid plans
Proton lists unlimited aliases, built-in two-factor authentication, secure sharing, dark web monitoring, file attachments, and Emergency Access among Pass Plus features. The pricing page also names Pass Family and Proton Unlimited. Its captured plan information does not establish dependable numeric prices, so check the live page for your country, billing period, taxes, and any introductory offer before deciding what the bundle is worth. Check Proton’s current plan information.
Bitwarden Premium and organization plans
Bitwarden’s © 2025 plan document lists TOTP authentication, encrypted attachments, vault health reports, and Emergency Access for Premium. It says individual Premium does not include secure data sharing: that requires an organization plan. The document describes a free organization for two users and up to two collections, and a Families organization for up to six users with unlimited secure sharing. Confirm that these details and any prices remain current before subscribing.
Rank #2
- Requires 3 "AAA" batteries (included)
- Unit auto-locks for 30 minutes after 5 consecutive incorrect PINs
The workflow distinction is important. Proton documents direct vault and item sharing, including links for recipients who do not use Pass; its link controls include expiration and view-count limits. Bitwarden’s sharing is described as organization- and collection-based. The detailed cross-product characterization comes from Proton’s comparison, not from independent usability testing. Read Proton’s sharing details and Proton’s comparison of Bitwarden.
Which service handles aliases better?
If you want to create hide-my-email aliases as part of the password-manager workflow, Proton’s listed allowance is a concrete differentiator: 10 aliases on Free and unlimited on paid Pass plans. Proton’s comparison says Bitwarden supports aliases through third-party integrations, rather than presenting them as the same built-in offering. Whether that difference matters depends on how often you use aliases and whether you prefer one integrated service or are comfortable setting up an external tool. Proton’s plan page and its Bitwarden comparison describe these features.
What can you conclude about security?
Proton says Pass uses end-to-end encryption for usernames, web addresses, passwords, and other metadata, and describes vault encryption using 256-bit AES-GCM. It also says its apps are open source and independently audited. These are Proton’s statements about its own product. Read Proton Pass security details.
Proton’s comparison says Bitwarden is open source too. That shared attribute can help readers inspect software, but it does not by itself establish which service is safer in actual use. The reviewed material does not provide an independent head-to-head security assessment, so it does not support naming a security winner.
Rank #4

Proton describes passkey support across plans and devices, but the available comparison does not establish current, independently verified feature parity between the two services. Proton’s passkey page notes device-specific caveats, including Android version requirements; check the current platform details before choosing based on passkeys. Review Proton’s passkey information.

Bitwarden’s plan document lists self-hosting as an option for certain individual plans and Families organizations; Proton’s comparison says Proton Pass does not offer it. That can matter if you specifically want to operate your own password-manager infrastructure. Self-hosting is not maintenance-free: the operator takes on responsibility for keeping the service available and managing the infrastructure. Check Bitwarden’s current documentation for the applicable plan and requirements before making it a deciding factor. Bitwarden plan document; Proton’s comparison.
What do the available prices establish for 2026?
They do not establish a reliable, current 2026 price comparison. The Bitwarden plan document is marked © 2025 and lists Premium at $10 per year and Families at $40 per year; those are figures from that dated document, not independently confirmed 2026 prices. The Proton pricing page lists plan names and features, but the captured information does not provide dependable numeric prices. Check each provider’s current pricing for your region, billing period, taxes, and discounts rather than comparing those older Bitwarden figures with an unverified Proton price.
How should you choose?
- Choose Proton Pass for closer consideration if built-in hide-my-email aliases, direct item or vault sharing, or share links are central to your routine.
- Choose Bitwarden for closer consideration if organization-based sharing suits your household or team, or self-hosting is a specific requirement.
- Compare the current free plans if you mainly need password storage and cross-device use; the published plan descriptions use different language for their allowances.
- Check plan boundaries before paying if you need sharing, attachments, authentication codes, monitoring, or emergency access. Features are grouped differently, and Bitwarden’s document makes sharing an organization-plan feature rather than an individual Premium feature.
- Do not decide on a claimed security winner based on the available comparison: it does not demonstrate superior real-world security for either product.
How do you move passwords to Proton Pass?
Proton says passwords can be imported by exporting them from another manager as a CSV and importing that file into Pass. An export may contain readable credentials, so handle it as sensitive data: keep it private during the transfer and remove the file when it is no longer needed. The available sources do not establish comparative migration testing between Proton Pass and Bitwarden. See Proton Pass product information.
