Pros and cons
Keeper Secrets Manager
Pros
- A free plan is available, and free and budget places Keeper in the free and budget segment, so a start costs nothing.
- Passkeys are supported and totp adds verification codes, covering the usual second factor inside the vault.
- Platforms span Windows, macOS and Linux, so the same account covers desktop, mobile, browser and command line.
Cons
- Its feature list is short, totp, so verification codes and passkeys are the extras rather than a wide menu.
- Plan capacity is fixed: the family plan includes 5 private vaults, up to 5 users, 10 GB secure file storage, so larger households plan around those limits.
- Budget buyers should compare tiers first: the site median entry price is €6.84 and the monthly median is €7.89.

Pros
- The listed free-plan features include unlimited logins, notes and credit cards, plus unlimited devices.

Who each suits
Keeper Secrets Manager

- ESET Brasil covers Windows, Windows Server and macOS including Windows Server, a platform the Keeper list does not name.
Proton Pass
Who it suits

Questions about each
Keeper Secrets Manager
What does Keeper cost, and what do I pay at renewal?+
Keeper has a free plan, and free and budget places it in the free and budget segment, so entry can cost nothing. Across the site the median entry price is €6.84 and the monthly median is €7.89. Read your chosen tier's renewal figure too, since a long-term rate can differ from the first one.
Is Keeper independently audited, and who runs it?+
The operator, Keeper Security, Inc., is based in the United States. It publishes SOC and ISO certifications plus FedRAMP High, and it runs quarterly third-party penetration testing. Data is encrypted with AES and elliptic-curve cryptography at device and record level, so stored records stay readable to the account holder.
Does Keeper handle passkeys and verification codes?+
Passkeys are supported, which suits sign-in on sites that have moved away from shared passwords. The feature list is short, totp, and covers verification codes, so the second factor travels inside the vault rather than sitting in a separate app.
Proton Pass
Which platforms are listed for Proton Pass apps?+
The provider lists Android, iOS, Windows, macOS and Linux.
