About this app

LastPass Authenticator offers effortless two-factor authentication for your LastPass account and other supported apps. With one-tap verification and secure cloud backup, LastPass Authenticator gives you all the security, without any of the frustration.

Safeguard your LastPass account by requiring two-factor authentication codes when signing in. Two-factor authentication improves your digital security by protecting your account with an additional login step. Even if your password is compromised, your account can’t be accessed without the two-factor authentication code.

You can even mark a device as “trusted”, so you won’t be prompted for codes on that device while your account remains protected by two-factor authentication.

To turn on LastPass Authenticator for your LastPass account:
1. Download LastPass Authenticator to your mobile device.
2. Log in to LastPass on your computer and launch “Account Settings” from your vault.
3. In “Multifactor Options”, edit LastPass Authenticator and view the barcode.
4. Scan the barcode with the LastPass Authenticator app.
5. Set your preferences and save your changes.

LastPass Authenticator can also be turned on for any service or app that supports Google Authenticator or TOTP-based two-factor authentication.

To login to your LastPass account or other supported vendor service:
1. Open the app to generate a 6-digit, 30-second code OR approve/deny an automated push notification
2. Alternatively, send SMS code
3. Enter the code into the login prompt on your device OR hit approve/deny request

- Generates 6-digit codes every 30 seconds
- Push notifications for one-tap approval
- Free encrypted backup to restore your tokens on a new/reinstalled device
- Support for SMS codes
- Automated set-up via QR code
- Support for LastPass accounts
- Support for other TOTP-compatible services and apps (including any that support Google Authenticator)
- Add multiple accounts
- Available on Android and iOS

Pros: There are so many options to export/import (QR code, JSON file, and LastPass server.) It has sorting(manually and automatically) and grouping. It can be locked with a passcode and fingerprint. It shows the next code when the current code is red and expiring. It's the best. Cons: No visual feedback for tapping on any rows on any page (they should be highlighted.) The rows of the Accounts are too tall. The text is much larger than my default device font. Too much scrolling.

I have been using LastPass Manager and LastPass Authenticator for about 3 years on my Samsung Galaxy S8. I can't say I ever had an issue with the two of them. I have over 100 randomly generated passwords and I sleep better knowing that all of them are super complex and all I have to remember is just one. Thanks for a great product. Update 2/1/2023: Over 5 years with LastPass and the 2MFA Authentication app. From the Galaxy S8, Note 10, Note 20, and S22 Ultra. I still never had an issue.

Its "OK." With exception to the backup feature, which is excellent, the rest of the app is minimally functional. Times are changing, long lists are not unusual. There needs to be a search field, and if there were also sorting and categorising features, the rating would be five stars. However the app has barely changed in all the years I've used it.

What's new

What's new: We are introducing a flow that shows how users can add TOTP codes to the app. This flow is useful for users who would like to protect their LastPass account as well as other 3rd party sites that support MFA. We have also improved on our feature which allows for users of the app to move from their old device to their new device. Finally, we have also made many minor updates to the user interface and fixed minor bugs found in previous versions of the app.
