Proton Pass is a strong fit if you want a capable free password manager, broad device support, and a privacy-focused design—especially if you already use Proton services. Its free plan includes unlimited logins and device sync, while several useful extras, including unlimited aliases, integrated 2FA, and sharing, are paid features. Proton describes its vault data and metadata as end-to-end encrypted, and its apps are open source; those are meaningful design and transparency claims, not guarantees that any service is invulnerable.
What Proton Pass does
Proton Pass stores logins and other sensitive items, helps fill credentials, and can create hide-my-email aliases. It is available through Android, iOS, Windows, macOS, and Linux apps, a web app, and browser extensions. Proton also lists passkey support among its capabilities. Check the current product pages for supported browser and operating-system versions if compatibility with a particular device matters.
For someone already using Proton services, Pass can be a convenient addition to that ecosystem. It can also be considered on its own; you do not need to treat ecosystem membership as the sole reason to choose a password manager.

Proton’s live pricing page says the free and paid plans both support unlimited logins on unlimited devices. That makes the free tier useful for someone who mainly needs to store and sync credentials, rather than a trial restricted to a small number of entries or devices. Plan names, prices, and included limits can change, so check Proton’s current pricing and plans before subscribing.
#1 Best Overall
- POWERFUL SECURITY KEY: The Security Key C NFC is the essential physical passkey for protecting your digital life from phishing attacks. It ensures only you can access your accounts.
- WORKS WITH 1000+ ACCOUNTS: Compatible with Google, Microsoft, and Apple. A single Security Key C NFC secures 100 of your favorite accounts, including email, password managers, and more.
- FAST & CONVENIENT LOGIN: Plug in your Security Key C NFC via USB-C and tap it, or tap it against your phone (NFC) to authenticate. No batteries, no internet connection, and no extra fees required.
- TRUSTED PASSKEY TECHNOLOGY: Uses the latest passkey standards (FIDO2/WebAuthn & FIDO U2F) but does not support One-Time Passwords. For complex needs, check out the YubiKey 5 Series.
- BUILT TO LAST: Made from tough, waterproof, and crush-resistant materials. Manufactured in Sweden and programmed in the USA with the highest security standards.
| Capability | Free plan | Paid plans |
|---|---|---|
| Logins and devices | Unlimited logins on unlimited devices, according to Proton’s pricing page | Unlimited logins on unlimited devices, according to Proton’s pricing page |
| Aliases | Alias availability is subject to the current plan limits | Proton lists unlimited aliases as a premium capability |
| Vaults | Fewer vault options than paid plans | Additional vaults |
| Two-factor authentication | Integrated authenticator is a premium capability | Integrated 2FA authenticator |
| Sharing | Check current plan details for any included sharing | Secure item sharing |
| Monitoring and protection | Check current plan details | Dark web monitoring and advanced account protection are listed among premium capabilities |
The comparison reflects features described on Proton’s pricing page; it is not a substitute for the live plan table, which may specify limits or eligibility more precisely. If you only need a synced login vault, the free plan may cover the core job. If you expect to use many aliases, separate vaults, built-in 2FA, monitoring, or sharing, compare the current paid price with your actual needs rather than assuming every premium feature is necessary.
Is Proton Pass secure?
Proton says usernames, passwords, and metadata—including usernames and website addresses—are end-to-end encrypted and inaccessible to Proton. It describes vault encryption as 256-bit AES-GCM. In practical terms, this is Proton’s published account of how it protects stored vault data; it should not be read as proof that a password manager, device, account, or user can never be compromised. See Proton’s security description for its explanation of the design.
Rank #2
- Requires 3 "AAA" batteries (included)
- Unit auto-locks for 30 minutes after 5 consecutive incorrect PINs
Proton also says its Pass apps are open source and that audit reports are public. Open source lets outside parties inspect published code, while an audit provides a scoped assessment at a particular point in time. Neither fact by itself establishes that every version, configuration, or user device is free of weaknesses.
What the 2026 audit says
In an announcement dated May 12, 2026, Proton said Recurity Labs audited the browser extensions, mobile and desktop apps, and command-line interface between January and April 2026. Proton reported that the audit found no remote exploits or encryption bypasses, and that desktop memory-handling issues were fixed in retesting. The announcement attributes the assessment “well above par” to Recurity Labs. Read the audit announcement and its linked report for scope and detail; the findings are not a claim that Proton Pass cannot be hacked.
Proton Pass pros and cons
Potential strengths
- The free tier offers unlimited logins and device sync, according to Proton’s current pricing page.
- Apps, a web app, and browser extensions cover major desktop and mobile platforms.
- Hide-my-email aliases can be used alongside credentials, and Proton lists passkey support.
- Proton’s stated encryption design includes metadata as well as passwords and usernames.
- Published open-source apps and audit material give privacy-minded users more to inspect than an unsupported security promise.
- Paid options include features such as additional vaults, integrated 2FA, secure sharing, and monitoring.
Potential drawbacks and questions
- Some conveniences that may matter in daily use are paid, so the free plan’s value depends on whether you need more than a synced login vault.
- Pricing and feature limits are subject to change; compare the current price with the premium features you will actually use.
- Independent reviews have raised questions about value and support. Security.org’s review, last updated March 23, 2026, praised the free tier and privacy features but criticized pricing and lack of live chat. Those are that reviewer’s dated assessments, not guarantees of today’s support channels or pricing.
- Emergency access is a feature whose reported status has changed over time. Security.org said it was absent in its March 2026 review, while WIRED’s 2025 review said Proton had launched it shortly before publication. Confirm current availability and behavior in Proton’s documentation before relying on it for a recovery plan.
- Importing credentials, autofill behavior, and support quality are practical considerations that depend on your devices and workflow; the cited reviews discuss evaluation concerns but do not establish how the service will behave in your specific setup.
For the dated third-party assessments, see Security.org’s review, updated March 23, 2026 and WIRED’s 2025 review. Their observations can help identify questions to ask, but should not replace checking current product details.

Choose based on the tasks you need a password manager to handle, not just a privacy label or a long feature list. Proton’s product page names Bitwarden, 1Password, NordPass, LastPass, Dashlane, and Keeper in its own comparison; treat that as a vendor-authored list of alternatives, not independent proof that Proton is superior. Compare candidates on the dimensions that affect your use:
Rank #4
- FIDO-ONLY FUNCTIONALITY: Supports FIDO2 (passkeys) and FIDO U2F protocols for passwordless and second-factor authentication. Does not support OTP, TOTP, Smart Card (PIV), or other advanced features - upgrade to YubiKey 5 Series for extended functionality
- SECURE AND CONVENIENT: Passwordless MFA login with the YubiKey Bio authenticator and biometric information using a fingerprint, with a PIN as a fallback. Simply plug in via USB and use your fingerprint to authenticate
- DEVICE & OS COMPATIBILITY: Compatible with Windows, macOS, ChromeOS, and Linux. Works seamlessly with supported services like Google and Microsoft accounts, and major password managers. See the full compatibility list at "Works With YubiKey"
- DURABLE & RELIABLE: Resistant to tampering, water, and crushing. No batteries or network connectivity required, offering dependable authentication without any downtime. Securely manufactured in USA & Sweden
- Yubico Authenticator App - Fingerprint enrollment, passkey management and PIN configuration available via the app app - Upgrade to YubiKey 5 Series to generate one-time-passwords (OTP) via Yubico Authenticator and for advanced compatibility (OATH, PIV)
- Privacy and transparency: Review each service’s encryption explanation, published audit evidence, and what data it says it can access.
- Cost and free limits: Check current plan prices and limits, including whether the free tier covers the number of devices and features you need.
- Device fit: Confirm support for your operating systems and browsers, then consider autofill behavior on the devices where you sign in most.
- Credential workflow: Decide whether you need passkeys, email aliases, or an integrated authenticator, and whether those are available on the plan you would use.
- Sharing and recovery: If you share credentials with family or colleagues, verify the available sharing controls. If another person must access your vault in an emergency, confirm the current emergency-access feature and recovery process before depending on it.
- Help when something goes wrong: Check the current support channels and decide whether they meet your expectations.
Proton Pass is most compelling when its free core meets your needs or its paid privacy and convenience features fit your workflow. Someone who depends on a particular sharing model, support channel, or emergency-access setup should verify those details before moving a vault.
