Our verdict on each
Keeper
Keeper suits readers who want a password manager they can open on a free plan and grow into later, with passkeys, on-device encryption that keeps records unreadable to the provider, and a family plan that covers 5 private vaults, 10 GB file storage.
Proton Pass
Proton Pass’s listed free-plan features include unlimited logins, notes and credit cards, unlimited devices, 10 hide-my-email aliases, and passkey support. The provider also lists apps for Android, iOS, Windows, macOS and Linux, and says all fields, including usernames and web addresses, are encrypted. These are provider descriptions, not an independent security assessment.

Pros and cons
Keeper
Pros
- A free plan is included, and most managers in this comparison offer one too (72.3%).
- Records are encrypted on the device using AES with elliptic-curve cryptography, so a stored vault stays unreadable to the provider, and TLS covers traffic in transit.
- Coverage spans Windows, macOS and Linux, so one vault reaches desktop, mobile, browser extension and web app.
Cons
- The service runs under Keeper Security, Inc. and US terms, which readers in other legal regimes should weigh before storing sensitive logins.
- Phone and chat support are less common than email and help centres in this comparison, at 41.1% and 34.4% of brands, though Keeper's email, chat and phone includes both.
- Shared allowances stop at 5 private vaults, 10 GB file storage, so a household that stores a lot of files needs a bigger tier than the family plan.
Proton Pass
Pros
- The listed free-plan features include unlimited logins, notes and credit cards, plus unlimited devices.
- The provider lists 10 hide-my-email aliases and passkey support.
- Apps are listed for Android, iOS, Windows, macOS and Linux.
Who each suits
Keeper
Who it suits
- Readers who want to try a password manager on a free plan before paying for anything.
- Households that need separate private vaults plus shared file storage, which is what 5 private vaults, 10 GB file storage sets out.
- People who want to reach help through email, chat and phone, including live chat and phone.
Who should look elsewhere
- People who want one ecosystem for everything, since Apple's iOS, iPadOS and macOS covers its own devices and nothing else.
- Teams that need Windows Server coverage, since Windows, Windows Server and macOS lists it and Keeper's Windows, macOS and Linux does not.
- Readers who expect every manager in the comparison to hand out a free plan, since Total Password has none while Keeper does.
Proton Pass
Who it suits
- People who want a password manager with listed apps across desktop and mobile platforms and passkey support.

Questions about each
Keeper
Does Keeper have a free plan?+
Yes. Keeper offers a free plan, and so do most managers in this comparison (72.3%). The free tier shows how the vault behaves with your own accounts, while the paid family plan is where 5 private vaults, 10 GB file storage comes in.
What kind of prices do these password managers sit in?+
Across the brands compared here, monthly plans run as low as €0.87 and as high as €63.95, while longer terms sit between €0.73 and €99. A median long-term price of €3.97 shows where a multi-year commitment usually lands.
What does the Keeper family plan include?+
The family plan covers 5 private vaults, 10 GB file storage. That is the sharing allowance: private vaults for each member of the household plus file storage inside the same subscription. It is what makes Keeper useful for a family rather than a single person, and the main reason to look past the free plan.
Proton Pass
Which platforms are listed for Proton Pass apps?+
The provider lists Android, iOS, Windows, macOS and Linux.
