Proton Pass review

Proton Pass generates and stores passwords, syncs them across devices automatically, and alerts you to breaches, according to Proton’s homepage. It’s available on a free plan, so you can try its basic password-management features without paying first.

The plan choice matters if you’re switching an existing vault. Free includes two vaults, unlimited logins and notes, unlimited devices, and sharing with up to two people. Proton’s listed paid options include Mail Plus and Unlimited, with higher vault and sharing limits on Unlimited. The pricing page shows annual-billing rates of $3.99 per month for Mail Plus and $9.99 per month for Unlimited; the displayed monthly prices are $4.99 and $12.99.

Proton says its apps are open source and independently audited. That statement needs context: a Reddit commenter says Proton publishes client code but not its server code. We’d treat the scope of “open source” as something to verify before making it a deciding reason to switch.

The clearest selling point is the free plan’s combination of device coverage and basic capacity. Proton lists unlimited devices, logins, and notes on Free, alongside password generation, automatic syncing, and breach alerts. For someone leaving a paid manager or starting fresh, that’s a useful set of basics without a recurring bill.

• Free: Two vaults, unlimited logins and notes, unlimited devices, and sharing with up to two others.
• Mail Plus: The same listed vault, login, note, device, and sharing limits as Free. The pricing page lists it at $3.99 per month when billed annually, or $47.88 per year; $4.99 per month is shown as the monthly price.
• Unlimited: 50 vaults, a built-in 2FA authenticator, unlimited logins and notes, and sharing with up to 10 others. It costs $9.99 per month on annual billing ($119.88 per year), with $12.99 shown as the monthly price.

That gives switchers a simple choice: stay free if two vaults and two-person sharing are enough, or pay for more vaults, broader sharing, and the authenticator. In one Reddit discussion comparing Proton Pass with Bitwarden, a commenter favored Proton’s user experience, though that is an individual opinion, not a broad finding.

The free plan’s two-vault cap is the main limit to check before migrating. It allows unlimited logins and devices, but a vault limit can still matter if you separate personal, work, or shared credentials. Free sharing stops at two other people. Unlimited raises those caps to 50 vaults and 10 people, but costs $9.99 per month with annual billing, or $119.88 a year.

The open-source claim also deserves scrutiny. Proton says all its apps are open source and independently audited, while a commenter in a Reddit thread says the client implementations are public but the server code is not. That’s a user’s account, not confirmation from Proton, but it points to a distinction worth checking if source availability is central to your choice.

Some costs are unclear from the published pricing details. Proton Scribe is listed as an add-on with a free trial, but its price is not published. A possible iOS in-app surcharge is also mentioned without an amount. If you need either, confirm the cost before switching; otherwise, the published prices may not tell the whole story.

Proton Pass Free costs $0 and includes two vaults, unlimited logins and notes, unlimited devices, and sharing with up to two people. That is a useful free tier, but the two-vault cap is the main reason to check your setup before switching.

Mail Plus is listed at $3.99 per month when billed annually ($47.88 per year); its listed features match Free. The pricing page shows $4.99 struck through as the monthly rate. Unlimited costs $9.99 per month billed annually ($119.88 per year), with $12.99 shown as the struck-through monthly price. That is a $6-per-month increase over annual Mail Plus pricing. Unlimited adds 50 vaults, a built-in 2FA authenticator, and sharing with up to 10 people; both paid plans list unlimited logins and notes.

Proton Scribe is a separate add-on with a listed free trial, but its price is not published. The page also notes a possible iOS in-app surcharge without giving an amount. Check the checkout total and billing period before paying.

The published material does not specify an import process, supported import formats, or export options, so we can’t say how much work a migration takes or how easy it is to leave. Check Proton’s current documentation for those details before moving your password store, and keep a separate backup until you have confirmed your data is available in the new manager.

The clearest switching constraint in the published plan details is vault capacity: Free and Mail Plus list two vaults, while Unlimited lists 50. Free and Mail Plus also limit sharing to two people; Unlimited lists sharing with up to 10. If your current setup depends on more vaults or broader sharing, compare those caps with your needs before moving.

Proton says its apps are open source and independently audited, but the verdict flags that people who require fully public server code may not find that sufficient. The published material includes no Reddit reports about why users leave Proton Pass, so we can’t attribute any specific switching complaints to Reddit.
