How to Turn On 2FA for LastPass

Please note: Specific instructions for enabling 2FA are subject to change without notice. Please check with each website or app for the most up-to-date information on this feature.

LastPass offers a variety of "Multifactor authentication" options to protect accounts. This tutorial will walk you through each option and how to enable it on your account.

First, go to the LastPass Vault > Account Settings > Multifactor Options. 

OPTION 1: If you would like to use Google Authenticator,  first ensure you’re using the latest LastPass browser extensions and mobile clients everywhere. You will also need a supported mobile device to run the Google Authenticator application.

1. Install the Google Authenticator application on your mobile device. Google officially supports Android, iOS (iPhone, iPod Touch, or iPad), and BlackBerry devices. Once you have the Google Authenticator application running on your mobile device, go to and follow the instructions there to finish setting up Google Authenticator.

2. You will be prompted to use a Bar Code scanning app (Androids,  iPhones and supported devices with cameras) to scan your unique bar code or you can manually enter the Google Authentication Key found on that setup page.

3. After your LastPass account is registered within the Google Authenticator app, the next time you login to LastPass on an untrusted device, you will receive the Google Authentication dialog. Go to your Google Authenticator App and input the current authentication code you see in the app into this dialog. If the code expires before you have a chance to authenticate, simply use the next code that appears in the app.

OPTION 2: YubiKey is a key-sized device that you can plug into your computer’s USB slot to provide another layer of security when accessing your LastPass Account. YubiKeys are a secure, easy to use two-factor authentication device that are immune from replay-attacks, man-in-the-middle attacks, and a host of other threat vectors. This is a premium feature, and the device must be purchased through for $25. Five YubiKeys can be associated with one LastPass account.

1. Once you have purchased and received your YubiKey, you can enable the device and manage your preferences by launching your Account Settings and clicking on the ‘YubiKey’ tab.

2. To add a new YubiKey to your LastPass account, enter the device in your USB port, click in the first empty YubiKey field, and lightly press your YubiKey on the grooved circle. You will need to enter your LastPass Master Password to save any updates you have made to your YubiKey settings.

3. After the field is filled, you can specify your YubiKey preferences:

  • YubiKey Authentication: Enable or disable your YubiKey multifactor authentication. When enabled, you will be prompted to enter the YubiKey data the next time you login to LastPass.

  • Permit Mobile Device Access: Controls whether mobile devices that do not possess USB ports, such as a smartphone, will be allowed to bypass YubiKey multifactor authentication when enabled.

  • Permit Offline Access: Controls whether access to your vault will be allowed when you are not connected to the Internet. Allowing offline access to your vault is slightly less secure since YubiKey OTPs can not be validated, and only the static portion of the key is validated.

4. To begin using your YubiKey, be sure that the “YubiKey Authentication” field is marked as “Enabled.”

5. To save changes to your YubiKey preferences, click “Update” before exiting the Account Settings dialog.

OPTION 3: LastPass supports multifactor authentication with Duo Security. To use Duo Security, a Duo account is required. Register for an account at

7. Enter the Integration key, Secret key, and API hostname from before.

8. Switch Duo Security Authentication to “Enabled.”

9. A popup will appear to enroll your mobile device. Select the type of device that you would like to enroll and then click the “Continue” button. You will then be given on-screen instructions on how to enroll each specific device. Note that LastPass only supports one device at this time. Once you have enrolled the device(s) that you would like to use for Duo authentication, you can then use it to authenticate you in the login process.

OPTION 4: LastPass has support for various fingerprint readers, including Windows Biometric Framework, as a Premium feature.

OPTION 5: LastPass Premium members can use an ordinary USB thumb drive as a second form of authentication when logging into their LastPass account.

2. On your first run, you will be prompted to activate the software by Adding your LastPass login to the user list. Then, you will be sent an e-mail asking you to confirm the registry of Sesame. By default, the email link will expire after 10 minutes to protect your security. If you click on the link and it says ‘Link Expired’,  re-send yourself the activation link and try again.

Once activated, Sesame will create secure one-time passwords (OTPs) that are subsequently required to login. You have the choice to copy the OTP to the clipboard or launch the browser and pass the value automatically.

OPTION 6: Transakt is an app developed by Entersekt to bring banking-grade two-factor authentication to your mobile device. Transakt works with LastPass to enable you to authenticate your login by responding to a simple Accept or Reject prompt directly on your mobile phone or tablet.Transakt protects you against threats such as phishing, man-in-the-middle, man-in the-browser, and replay attacks.
