Who each suits
LastPass US LP
Who it suits
- People moving between a Windows desktop, a Mac laptop and a phone who want one vault
- Households sharing logins through LastPass Families, which covers LastPass Families: 6 Premium accounts
- Users who keep authenticator codes next to their passwords
Who should look elsewhere
- Total Password, which has no free plan, so you pay from the first day
- Apple Inc., whose apps run on iOS, iPadOS and macOS only, for buyers who stay inside that ecosystem
- ESET Brasil, which lists Windows, Windows Server and macOS, for teams that also cover Windows servers
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.

Questions about each
LastPass US LP
Is there a free version of LastPass?+
Yes. A free plan is available and includes 1 of storage. It covers the same Windows, macOS and Linux range as the paid tiers, so you can start at no cost and move up later if the limits get in the way.
What does the free trial cover?+
The paid tier can be tried for 30. That window sits alongside the free plan, so you can compare what a paid vault adds before committing. Trial accounts use the same AES-256 encryption with PBKDF2 hashing and SHA-256 salting as every other tier.
Proton
How much is Proton Pass at the entry price?+
Proton Pass starts at $4.99, and there is a free plan beside it. The paid tiers widen the set of features, so the entry price only pays off if you want more hide my email aliases, passkeys and password health alerts.
What does the free plan leave out?+
The free plan covers as many logins, notes, cards and devices as you like, but it leaves out the authenticator app, sharing with other people, file attachments and dark web monitoring. Those sit on paid Pass plans, where entry starts at $4.99.
