Hey folks,

You've been asking us a lot of questions about importing data from LastPass, so we're posting this announcement with resources, known issues, and frequently given answers. We hope you find it helpful – please read through it before contacting 1Password Support. If your question isn't answered, don't hesitate to email [email protected] for more assistance.

Thank you!

Getting started

Before you proceed, make sure your have the latest version of 1Password installed.

There are two ways to move your data from LastPass to 1Password:

  1. Import your data using the 1Password desktop app, which requires you to install the 1Password app, sign in to your 1Password account, then enter your LastPass credentials. 1Password will then try to move all of your account data automatically. For full instructions and details, see our Move your data from LastPass to 1Password support article.
  2. You can also import LastPass data on the 1Password website. The support article provides specific steps export your data on LastPass.com and import it on 1Password.com At this time, LastPass CSV files cannot be imported using the 1Password app.

Current issues and next steps

1Password indicates that you may be offline

This error can occur when there is an unknown connection error, and will often be seen when a device is already online with a good internet connection.

Visit the LastPass website and sign in with your LastPass account, then try importing again. If the issue persists, email a diagnostics report to [email protected] for help.

export failed: failed to log in: unifiedloginresult

LastPass detected the login as potentially suspicious and blocked it. Check your email for a message from LastPass and follow the directions to approve the login. Then try importing again.

If your LastPass account requires two-factor authentication or MFA to sign in

Update to the latest version of 1Password and try again.

Security key's are not currently supported and will need to be replaced with another form of MFA. In all other cases, try importing again after completing an MFA prompt, or email [email protected] if you are still unable to complete MFA or sign into LastPass with the 1Password import tool.

If your LastPass account requires Single sign-on (SSO)

1Password now supports signing into LastPass with single sign-on (SSO). Please note:

  • While 1Password currently only supports Okta, signing in with other identity providers may also work.
  • The Sign in redirect URI for 1Password is onepassword://import/login/sso, it must be added to your LastPass application Login settings (learn how here), like so in the following screenshot for Okta:

If you’re unable to sign in, disable SSO at LastPass or upload your CSV file on 1Password.com.

We continue to explore support for additional providers. Please email [email protected] and let us know which identity provider your company uses.

Malformed file error

This indicates that a file attachment cannot be decrypted. Update to the latest version of 1Password and try again.

If the issue persists, these steps have helped some customers:

  • If the error message indicates the file is in your account, try changing your LastPass master password, wait a short time, and try again. Changing your password can cause account data to be re-encrypted at LastPass and 1Password may then be able to import it.
  • If the message indicates the file is in a shared folder, the shared folder in question needs to be located. Its contents can then be moved to another shared folder, which will cause the data to be re-encrypted and may allow 1Password to import it. To locate which shared folder(s) contain the malformed file, use the LastPass sharing center to hide passwords from all but one shared folder, then try importing again. Repeat this process after changing which shared folder doesn't hide its passwords until the import breaks, and that shared folder likely contains a malformed file.

Nothing is imported

Contact [email protected] for help.


Update to the latest version of 1Password and try again.

failed to convert data to a number: cannot parse integer from empty string

Update to the latest version of 1Password and try again. Contact [email protected] for help if the issue persists.

Import failed: Unable to export data from LastPass

  1. Make sure you have updated to the latest version of 1Password.
  2. Attempt to import from LastPass using the File > Import option in the 1Password app.
  3. If there is a "Importer failed: unable to export from LastPass" error, or any other error about "apps are not supported", install and use the LastPass app from the Microsoft Store to review any app data saved in LastPass. Manually recreate this data in 1Password, then delete the entries in LastPass.
  4. Try importing with 1Password again.

failed to perform HTTP operation: failed to get response from 'getSharedFolderRestrictions.php

This indicates that some permission, restriction, or policy within LastPass is preventing 1Password from accessing or exporting this specific shared folder. In most cases, it's quite difficult to find and fix the underlying cause of the error, but we have identified a work around to import the information from an impacted shared folder. Here's how it works:

  1. If you haven't already, Update to the latest version of 1Password and try again.
  2. Using the list of errors from the last 1Password import attempt, pick one shared folder which didn't import.
  3. Sign into the LastPass website and create a new shared folder. Give it a name the indicates it replaces the original version of the shared folder.
  4. In the original or "broken" shared folder, select all of the items in it, and move them to the newly created shared folder.
  5. Now open the 1Password app and attempt to import again. 1Password should skip the broken folder because its empty, and import all of the items in the newly created shared folder.
  6. If that process works, repeat it for the remaining shared folders that couldn't be imported, then import in 1Password again. 1Password will automatically track which shared folders are moved successfully to help avoid duplicating them in future import attempts.

If your'e still unable to import a shared folder, contact [email protected] for help.

If you encounter another error not seen here

Update to the latest version of 1Password and try again. Contact [email protected] for help.

How to use the 1Password beta (and how to switch back)

The beta version of 1Password is updated more frequently and has new features and improvements that are being tested. If one of the above problems suggests trying the beta, see our Use 1Password beta releases support article for steps to switch to the beta, and for directions to automatically switch back to the production build of 1Password after the next release.

If you need to switch back to production right away, see the "How to reset and revert to production" section below.

    1Password nightlies

    If one of the above problems suggests using the 1Password nightly version, here's what you need to know:

    • The 1Password nightly version is updated much more frequently than the production and beta versions of 1Password. It includes the latest features and improvements, but is also the least tested.
    • You may encounter rough edges and bugs when using the nightly version, so we don't recommend using it in normal circumstances. It's best to switch back to the production version of 1Password as soon as you no longer need to use the nightly version. See our "How to reset and revert to production" section below.

    To switch to the nightly version of 1Password:

    1. Make sure you have a copy of your Emergency Kit stored somewhere outside of 1Password, in case something goes wrong and you have trouble accessing your account. You can always sign in as long as you have your Secret Key and account password.
    2. Open and unlock 1Password on your Mac, Windows, or Linux device.
    3. Open the settings (Ctrl + , on Windows and Linux, or Cmd + , on Mac)
    4. Click on Advanced in the sidebar.
    5. Change Release channel to "Nightly"
    6. Change to the About tab.
    7. Click "Check for updates". 1Password will then download and install the update. When it's done, restart 1Password to use the nightly version.

    How to reset and revert to production

    Before proceeding with the rest of these steps, sign in to 1Password.com in your web browser and review recent changes you've made to make sure your data is up to date. Double-check any items you recently created or edited, plus any others you know to be important.

    1. Make sure you have your Emergency Kit for every 1Password account you have, and can sign in to 1Password.com without using 1Password to autofill the information. If you can't sign in online, do not proceed with these directions. Stop here and contact [email protected] for help.
    2. Quit all web browsers with 1Password in your browser (the extension) installed.
    3. Fully quit 1Password, using the icon in the menu bar or system tray.
    4. Remove 1Password from your device.
    5. Reset 1Password to remove 1Password data from your device, if you didn't already do this as a part of the last step.
    6. Download and reinstall 1Password.

    Sign into your account(s) as usual and you will be back on the production version of 1Password. If you have any problems, email [email protected] for help.

    How and when to send a diagnostics report

    1Password will offer to generate a diagnostics report if the import encounters an error. If 1Password Support has asked you for it, please generate the report and attach the file to a reply to your support ticket. The diagnostics report contains all of the logs 1Password has recently generated, and will include details about all past import attempts, so there's no need to collect multiple diagnostics reports.

    There is no need to send the diagnostics report to 1Password unless this post hasn't helped and you need to contact 1Password for support. 1Password diagnostics reports generated by 1Password 8 contain very little personally identifiable information, and none of your vault data. For more details, see our About 1Password diagnostics information support article.


    Importing a CSV in the app is broken.

    It's not currently possible to import a CSV file exported from LastPass using the 1Password app. Please follow the directions in our Import your LastPass data on 1Password.com support article to import this file on 1Password.com.

    When will a specific problem be fixed?

    Due to the nature of software development, it's difficult to predict when an issue will be fixed. Even if our development team is close to fixing an issue, there are still delays as the update goes through quality assurance testing, any remaining issues are fixed, and the update potentially waits to be included in the next release.

    • For the latest news on 1Password's LastPass import features, bookmark and check this page often.
    • To learn about other recent updates to 1Password, Visit 1Password Releases which has update notes for the production and beta versions of 1Password and 1Password in the Browser.

    What to do with items tagged LastPass

    All data that has been imported from LastPass will include the LastPass tag, so you know where it came from and can update it as needed. You can remove the tag at any time.

    To view your tagged items, click a tag in the sidebar. You can also search 1Password for tags.

    What to do with items tagged for repair

    If the import tool encountered any problems while moving an item to 1Password, it will be tagged with !-repair-items-lastpass. Please see Move your data from LastPass to 1Password for step-by-step directions to review the item in 1Password, compare it to LastPass, and manually move any corrupted or missing data to 1Password.

    How can I delete many vaults at once?

    Due to the permanent and destructive nature of the action, only one 1Password vault may be deleted at a time. Deleting a vault also deletes all the data it contains. There is no process to restore a deleted vault, or items that were in a vault when it was deleted.

    To permanently remove a vault and all its contents:

    • On Mac, Windows, or Linux: Right-click the vault in the sidebar and choose Delete Vault.
    • On 1Password.com: Click More Actions > Delete Vault.

    Is there any reporting or auditing around which team members have imported, if they ran into errors, or how much data they moved?

    Not at this time. If this feature is critical to your team, email [email protected] and let us know.

    I got a database error and can’t open 1Password

    If you've used a newer version of 1Password, such as the beta or nightly version, it may include updates to the local 1Password database that is kept on your device, making it incompatible with earlier versions of 1Password. If this prevents you from opening the 1Password app, see the "How to reset and revert to production" section on this page, or contact [email protected] for help.
