Switching password managers can feel intimidating, especially if you have years of logins, secure notes, payment cards, and shared credentials stored in LastPass. The good news is that moving from LastPass to 1Password is straightforward if you follow a careful process and protect your exported data along the way.
TLDR: Export your LastPass vault as a CSV file, import it into 1Password, verify that your items transferred correctly, then permanently delete the unencrypted export file. Before you begin, set up your 1Password account, install the app and browser extension, and make sure you have access to your LastPass account. Treat the exported CSV as highly sensitive because it contains readable passwords. After migration, update your browser autofill settings and enable two factor authentication for stronger account protection.
Before You Start: Understand What Will Move
LastPass and 1Password organize information differently, so not every item will always appear in exactly the same format after import. Most common data transfers well, including:
- Website logins, such as usernames, passwords, and URLs
- Secure notes, depending on the format used in LastPass
- Credit card and identity details, although some fields may need review
- Folders or categories, which may become tags or vault organization in 1Password
If you are using a family or business account, plan the migration carefully. Shared folders in LastPass may not map perfectly to shared vaults in 1Password. It is best to migrate your own account first, confirm the results, and then decide how to recreate shared vaults for family members or teams.
Step 1: Create and Secure Your 1Password Account
Before exporting anything from LastPass, create your 1Password account and make sure it is ready to receive your data. During setup, 1Password will ask you to create a strong account password. Choose something long, memorable, and unique. Do not reuse your LastPass master password or any password you have used elsewhere.
1Password also provides an Emergency Kit, which includes important account recovery information such as your Secret Key. Save this document securely. Ideally, print it and store it somewhere safe, such as a locked drawer or home safe. You can also keep a digital copy in an encrypted location, but avoid leaving it unprotected in downloads, email, or cloud storage.
After your account is created, install the 1Password desktop app and browser extension. This will make it easier to confirm that autofill works properly after migration.
Step 2: Prepare Your LastPass Vault
Before exporting, take a few minutes to clean up obvious clutter in LastPass. You do not need to perfect the vault, but removing clearly outdated entries can reduce confusion later. Look for duplicates, old test accounts, expired credit cards, and logins you know you no longer use.
If you have important secure notes or attachments, review them carefully. CSV exports usually handle text-based data, but file attachments may not transfer in the same way. Download any essential attachments separately and plan to add them manually to 1Password if needed.
Also make sure you are using a trusted computer. Avoid performing this migration on a shared, public, or work-managed device unless you fully trust its security. The export file will contain sensitive information in plain text, so the device must be protected.
Step 3: Export Your Data From LastPass
To migrate your vault, you generally need to export your LastPass data as a CSV file. The exact menu names may vary slightly depending on whether you use the LastPass browser extension or web vault, but the process is similar:
- Log in to your LastPass account.
- Open your vault.
- Find the option for Advanced Options or account tools.
- Select Export.
- Confirm your identity if LastPass asks for your master password or verification.
- Save the exported file as a CSV file on your computer.
Important: A CSV export is not encrypted. Anyone who can open that file can read your usernames, passwords, and other stored information. Save it only in a temporary location, such as your desktop or downloads folder, and do not upload it to cloud storage or send it by email.
Step 4: Import the CSV File Into 1Password
Next, sign in to your 1Password account in a browser. Look for the import option in your account settings or vault tools. Choose LastPass as the source if offered, then select the CSV file you exported.
The import tool will guide you through the process. In many cases, 1Password will recognize LastPass fields automatically and place items into the appropriate categories. If you are asked where to import the data, choose your personal vault unless you have a specific reason to use another vault.
After the import finishes, open the 1Password app and check several entries. Confirm that website addresses, usernames, passwords, and notes appear correctly. It is normal to find a few items that need manual adjustment, especially if your LastPass vault contained custom fields or unusual note formats.
Step 5: Review, Organize, and Fix Your Imported Items
Once the data is in 1Password, do not immediately delete your LastPass account. First, verify that the migration worked properly. Start with the accounts that matter most:
- Email accounts
- Banking and financial services
- Cloud storage accounts
- Work or school accounts
- Social media profiles
- Government, tax, or healthcare portals
Try logging in to a few important websites using 1Password autofill. If something fails, compare the imported entry against the original LastPass record. You may discover duplicate logins, outdated passwords, or missing website URLs.
This is also a good time to use 1Password’s security features, such as password health checks and watchtower alerts. These tools can help identify weak, reused, or compromised passwords. However, avoid changing dozens of passwords at once before confirming your migration is complete. Work gradually and prioritize critical accounts first.
Step 6: Delete the Exported CSV File Securely
After you have confirmed that your passwords imported correctly, delete the LastPass CSV file. This step is essential. Moving your passwords into 1Password while leaving an unencrypted export file on your computer creates a serious security risk.
Delete the file from its saved location, then empty your trash or recycle bin. If your computer has backup software that automatically copied the file, remove it from backups if possible. At minimum, make sure the file is not sitting in a synced folder such as desktop backup, cloud drive, or shared storage.
Do not keep the CSV as a backup. Your 1Password account is designed to store your vault securely. A plain CSV file is not a safe long-term backup method.
Step 7: Set Up Autofill and Disable Browser Password Saving
To avoid confusion, make 1Password your primary password manager. Install the 1Password browser extension for the browser you use most, then test it on a few websites. You should see 1Password offer to fill usernames and passwords when you click into login fields.
Next, disable your browser’s built-in password saving if you do not plan to use it. Browsers such as Chrome, Edge, Firefox, and Safari can save passwords independently, which may lead to duplicate prompts and outdated credentials. In your browser settings, turn off offers to save passwords and remove stored passwords if you are confident they are already in 1Password.
Step 8: Enable Two Factor Authentication
For better protection, enable two factor authentication on your 1Password account. This adds another layer of security when signing in from a new device. Use an authenticator app or hardware security key if available.
You should also enable two factor authentication on your most important online accounts, especially email, banking, cloud storage, and social media. Your password manager protects your credentials, but two factor authentication helps protect the accounts themselves if a password is ever exposed.
Step 9: Decide What to Do With Your LastPass Account
Once you are satisfied that your 1Password vault is complete, decide whether to keep or close your LastPass account. If you keep it temporarily, avoid updating passwords in both places, as this can create confusion. Treat 1Password as the source of truth from this point forward.
If you choose to delete your LastPass account, first make sure you have no remaining shared folders, billing obligations, or family members relying on it. Then follow LastPass’s official account deletion process. If you are not ready to delete it, at least change the master password, review security settings, and remove sensitive data you no longer need there.
Final Migration Checklist
- Created and secured your 1Password account
- Saved your Emergency Kit safely
- Exported LastPass data on a trusted device
- Imported the CSV file into 1Password
- Checked important logins and secure notes
- Deleted the unencrypted CSV file
- Installed the 1Password browser extension
- Disabled competing password saving where appropriate
- Enabled two factor authentication
Migrating from LastPass to 1Password is not difficult, but it should be done carefully. The most important rule is to protect the exported CSV file and remove it as soon as the import is complete. With a clean migration, a strong account password, and two factor authentication enabled, you can begin using 1Password with confidence.
