- Vaults use AES-GCM encryption with OpenPGP and ECC keys, and only the account holder can decrypt.
Cons
- Support runs on email, chat and help centre with no phone line.

- Extra storage costs $95.88 per TB per year beyond 5 GB free.
RoboForm

- Runs on Windows, macOS and iOS, covering desktop, mobile, Linux, Chrome OS and browser extensions.
- The Family plan bundles up to five Premium accounts under unified billing at a low monthly rate.

Who each suits
Proton
Who it suits

- Households and small teams that need shared accounts, since the Family plan bundles several Pass Plus accounts and an admin panel.

Who should look elsewhere
- Apple Hide My Email at $0.99 if email aliasing is the whole job, since Proton adds a VPN, storage and a password manager.

- EasyOptOuts at $19.99 for a single higher priced subscription, against Proton's $4.99 entry and a free plan.
RoboForm
Who it suits
- Readers who already keep passwords in a long-standing vault and want continuity
- Families sharing one bill across several Premium accounts
- People who need one vault across desktop, mobile and browser extensions
Who should look elsewhere

- Readers who want a plan priced only by usage across a wide server network
- Anyone looking for a product with a published regulator licence in the market
