Proton Pass vs Bitwarden 2026: free tiers, privacy, price

Pick Proton Pass if you want a Swiss provider, integrated email aliases and an app that sits neatly alongside other Proton services. Pick Bitwarden if you want self-hosting, a choice of EU or US cloud region, a long list of published audits and more control. Both are strong, privacy-respecting managers with free plans, so you will not regret either. This comparison is an editorial assessment based on vendor documentation, audit statements, feature lists and prices as of October 2026, not laboratory tests. For detail on each, read our Proton Pass review and Bitwarden review.

Security and encryption

Both products are zero-knowledge in design and encrypt data on your device. Bitwarden uses AES-256 with HMAC and lets you pick between PBKDF2 and Argon2id for key derivation. Proton Pass ties the vault to your Proton account and its end-to-end encryption model. In both cases a strong master or account password and a second factor are the essential protections. Our guide to two-factor authentication explains the options.

On audits, Bitwarden has the longer public track record, with reports by named firms such as Cure53 and others across several years, plus SOC 2 Type 2 and ISO 27001 certification. Proton had Cure53 audit its apps, browser extensions and API in May and June 2023, and the auditor called the overall state of security commendable, with a moderate number of findings and most limited in severity. Proton fixed all reported issues except one Android-specific issue of medium severity that it said platform limits prevent it from addressing. Read the Proton audit announcement for the details.

Passkeys and features

Both support passkeys, so you can use them as a passwordless login store. See passkeys explained if you are new to them. Proton Pass adds built-in hide-my-email aliases, integrated two-factor codes on paid plans and dark web monitoring on Plus. Bitwarden adds a deeper feature set, including a free standalone authenticator app, send features for sharing text and files, and vault health reports on Premium. Bitwarden also lets Premium users register several security keys, which is useful if you want a hardware key as a second factor.

Server location and jurisdiction

Proton is Swiss and says its infrastructure is in Switzerland, which is outside the EU but protected by Swiss privacy law. Bitwarden is American, which brings US jurisdiction, but you can select an EU cloud region at sign-up, and accounts do not migrate between regions automatically. Self-hosting is available only with Bitwarden. Our overview of European password managers places both in context.

Recovery

Account recovery differs. Bitwarden offers emergency access to a trusted contact on Premium, and the vendor cannot reset your master password. Proton ties recovery to its account system, which supports a recovery phrase or file, so store those securely. Neither provider can read your data if you lose the keys.

Export and switching

Both can export your data and import from many other managers, and KeePassXC also reads Proton Pass exports. CSV exports generally omit passkeys, so test the process before you rely on it.

Price

The base plans are free, and that is a real advantage over paid-only managers. On paid plans Bitwarden is a low flat annual price, while Proton Pass is tiered monthly and cheaper still if you are already paying for a larger Proton plan. Compare current offers directly, and read the free-tier details in our list of best free password managers.

Daily use and ecosystem

Both managers offer browser extensions, desktop and mobile apps, autofill and a generator. Proton Pass looks modern and sits comfortably next to Proton Mail, Proton VPN and the account that unlocks them, which is attractive if you already live in that ecosystem. Its hide-my-email aliases let you give each service a throwaway address, which cuts spam and helps when a site is breached. Bitwarden has the longer feature list and the larger community, with a free authenticator, Send for temporary sharing, a command-line tool, and many third-party integrations and import paths. If you like to tinker or work in an organisation, Bitwarden gives you more levers. If you want a calm interface and a tidy privacy story, Proton Pass is easier to explain to family members.

Sharing

Bitwarden’s free plan includes a two-person organisation for sharing, and the Families plan scales this to six users. Proton Pass lets you share vaults securely, and the number of recipients grows on paid plans. For a household that mainly shares streaming, utility and travel logins, either one works, so test the invitation flow with a real family member before you decide.

What we could not verify

Prices for Proton Pass were quoted in USD by comparison sources, and we could not confirm euro prices for your country. We relied on Proton’s published audit announcement from 2023 and could not confirm whether a more recent third-party audit has been completed, so check Proton’s security page. For Bitwarden, we did not read the full reports behind the audit list. Plans and limits change, particularly the number of aliases and sharing recipients on free tiers.

Switching from one to the other

Both managers import from each other and from many other tools, so a trial does not lock you in. Export from one, import into the other, and compare a sample of entries for missing notes, custom fields and attachments. Passkeys generally do not travel in CSV files, so list the sites where you rely on them and re-register those passkeys in the new vault while the old one still works. Delete the export file securely afterwards, because it contains your passwords in readable form. If you want to keep both for a month, mark one as read-only in your head, and do all new saving in only one of them so that the two do not drift apart.
