Pros and cons
Proton AG
Pros
- No-logs claims are audited rather than asserted: Securitum's audit (Securitum, 2026) sits behind a No activity logs policy.
- Free limits come with no caps on data or speed, no ads and no time limit.
- 10 simultaneous devices, above the ranked VPN median of 8.
Cons
- Support runs on email, chat and help centre, and there is no phone line among them.
- The free plan limits put you on a single device at medium speed with randomly selected countries, so constant use points at a paid plan.
- End-to-end encryption is marketed for Proton for Business, while the consumer plan encrypts only the connection from your device to Proton's servers.
RoboForm
Pros
- A free plan is included, and passkeys are supported alongside the listed features.
- 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.
Cons
- Support runs on email, chat and phone only, with no in-app guidance channel listed.
- The company is run from US under Siber Systems, Inc., so data handling is tied to US jurisdiction.
Who each suits
Proton AG
Who it suits
- Readers who want a VPN, a passkey vault and encrypted storage under a single account instead of separate subscriptions.
- Families sharing storage, since Pass Family covers several users and Pass Plus seats through a single admin panel.
- Teams buying under a business audience (business) who need GDPR, HIPAA and ISO 27001 certifications on file.
Who should look elsewhere
- Anyone needing more devices on a single account: Proton covers 10, while ESET Brasil plans run 3 to 25 devices.
- Readers choosing purely on server spread: AVG lists from 100 countries, a base close to Proton's from 140.
- Readers who want a different audit trail to compare: Session Technology Foundation lists Quarkslab 2021 against Proton's Securitum, 2026.
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
- Total Password, which has no free plan at all
- 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

Questions about each
Proton AG
What does Proton VPN cost, and how long are the commitments?+
The longest plan runs 24 months, the service is listed on a free model, and paid plans carry a 30-day money-back window. Across the ranked VPN field, monthly pricing has a median of €7.02 and long-term pricing a median of €3.97, which frames any quote you see.
Is there a free plan, and what are its limits?+
Yes. The free plan has no caps on data or speed, no ads and no time limit. It runs on a single device, reaches servers in a randomly selected group of countries and delivers medium speed, so the paid tier, which covers 10 devices, is the practical step for constant use.
RoboForm
Does RoboForm have a free plan?+
Yes, a free plan is included, and passkeys are supported alongside it. The paid Family plan adds up to five Premium accounts under unified billing, so a free vault can be the starting point before anyone pays. RoboForm is run by Siber Systems, Inc. from US.
What does the Family plan cover?+
The Family plan covers up to five Premium accounts on a single bill, which is the main reason to look past the free plan. It is listed as a budget model option, and the features on the paid tiers include totp. Support for paying customers runs through email, chat and phone.
