LastPass
A password manager from LastPass. It opens your LastPass vault, fills your logins and makes new passwords. The free plan is limited to one device type.
Why it's a strong pick
LastPass runs on Manifest V3, which LastPass says began with Chrome release 4.132.0 on 16 July 2024. The Chrome Web Store version is 4.156.0, updated 24 September 2026. The free plan keeps unlimited passwords. The trade-off: the free plan is limited to one device type, so it covers your computer or your phone, not both.
What it does
LastPass keeps your passwords, passkeys, usernames, payment methods and notes in an encrypted vault. The extension fills your logins on sites, makes new passwords and syncs the vault between devices. It supports multi-factor authentication. The listing says data is encrypted with AES-256 and that only you can unlock the vault. That is the developer's claim.
Key features
- Encrypted vault. Passwords, passkeys, payment methods and notes in one place.
- Autofill. Fills your saved logins on sites.
- Password generator. Makes a new password for each account.
- Secure notes. Store text you want kept private.
- Password sharing. Basic sharing is in the free plan, per LastPass's pricing page.
- MFA support. Works with multi-factor authentication.
Who it's for
LastPass fits people who use one device type, such as a laptop, and want a simple manager with unlimited passwords at no cost. It also suits anyone who wants to try Premium first: LastPass offers a 30-day trial. If you need your vault on a computer and a phone for free, read our LastPass alternatives page, or look at Bitwarden.
Is LastPass free?
Partly. LastPass has a free plan with unlimited password storage, autofill, dark web monitoring and basic password sharing. It is limited to one device type: computer or mobile, not both. Premium is paid, with a 30-day free trial. We print no prices, because they change. Check LastPass's pricing page for the current plans.
Does LastPass work with Manifest V3?
Yes. LastPass's release notes for version 4.132.0, dated 16 July 2024, say that release is a Manifest V3 build of the LastPass Chrome extension. Manifest V3 is Chrome's current extension format. The Chrome Web Store version we checked is 4.156.0, updated 24 September 2026.
Do I need an account to use LastPass?
Yes. The extension opens your LastPass vault, so you sign in with a LastPass account. Without an account there is no vault for it to open. The vault is where your saved logins, notes and payment methods live, so the extension has little to show until you sign in. Check LastPass's own pages for the current sign-up steps.
Is LastPass open source?
We could not confirm it. The developer does not state a source licence on the pages we read, so we do not call it open source. If open code matters to you, see Bitwarden or KeePassXC-Browser, which state their licences.
What permissions and data does LastPass use?
The Chrome Web Store page does not list permissions, and Chrome shows the exact list when you install. For data, the developer declares that it handles personally identifiable information, authentication information, location, user activity and website content. It says the data is not sold outside approved uses. Read the privacy policy before you install.

Good to know
Limit: the free plan covers one device type only, computer or mobile. LastPass's pricing page counts desktop and laptop browsers as "computer", and phones, smart watches and tablets as "mobile". Check which one you need before you choose the free plan.
