Pros and cons
AgileBits Inc.
Pros
- Apps cover macOS, iOS and watchOS, so a desktop, a phone, a watch and the main browsers all come under one subscription.
- Vault information is encrypted end to end, and Secure Remote Password keeps the account password off the server.
- Independent penetration tests and code reviews are published, so the audit trail is readable rather than asserted.
Cons
- There is no free plan, so every feature sits behind a payment.
- Support runs on email, help centre and community only, so urgent questions wait for email.
- The longest plan runs 12 months, so there is no multi-year rate to lock in.
Proton
Pros
- A single account covers a password manager, a VPN and end-to-end encrypted storage, with a free plan to start.
- Passkeys, custom domains and a Family plan with an admin panel suit single-user and shared use.
- 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.
- Free plan limits leave out the authenticator app, password sharing, attachments and dark web monitoring.
- Extra storage costs $95.88 per TB per year beyond 5 GB free.
Who each suits
AgileBits Inc.
Who it suits
- People who want one app for passwords, passkeys and one-time codes.
- Households that need shared vaults, since the family plan spreads vaults across the family on a promotional annual rate.
- Business buyers, since the audience AgileBits names is business.
Who should look elsewhere
- Apple Inc., whose monthly price of $0.99 is the lowest here, for buyers counting every dollar.
- Sinew Software Systems, at $1.99 a month, if a password vault alone is the whole need.
- MEGA, whose long-term plan price of $1.67 beats $3.99, for shoppers deciding on one number.
Proton
Who it suits
- Readers who want a password manager, a VPN and private files under a single subscription rather than separate products.
- Households and small teams that need shared accounts, since the Family plan bundles several Pass Plus accounts and an admin panel.
- Buyers who care about open source under a copyleft licence, outside security audits and a public bug bounty.
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.
- Apple Inc. at $0.99 when aliasing is the priority; Proton's $4.99 entry brings a VPN, storage and password manager in the same account.
- EasyOptOuts at $19.99 for a single higher priced subscription, against Proton's $4.99 entry and a free plan.
