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.
Which platforms does LastPass run on?+
It runs on Windows, macOS and Linux. That mix spans desktop systems, the main browsers, phone platforms and a watch, so a single vault follows you between devices. Nothing in the list ties you to one browser or phone maker.
Proton Pass
Which platforms are listed for Proton Pass apps?+
The provider lists Android, iOS, Windows, macOS and Linux.
