Moving from LastPass to 1Password is a smart way to regain control of your digital vault, but the process deserves care. Your password manager contains some of your most sensitive information: logins, secure notes, credit cards, identities, and sometimes Wi Fi passwords or software licenses. The good news is that importing your LastPass data into 1Password is usually straightforward, as long as you export the right file, import it correctly, and verify your vault before deleting anything.
TLDR: Export your LastPass vault as a CSV file, then import that file into 1Password using the web app or desktop app. Before you begin, make a backup, avoid editing the file unless necessary, and remember that CSV files are unencrypted while stored on your computer. After importing, check that your logins, notes, and other items transferred correctly, then securely delete the exported file.
Before You Start: Know What Will Transfer
LastPass and 1Password organize data in slightly different ways, so it is important to understand what normally imports cleanly and what may need extra attention. Most standard website logins transfer well, including usernames, passwords, website URLs, folder names, and notes. Secure notes and payment cards may also import, depending on how they were stored and how the export file is structured.
However, some data may not move perfectly. Attachments, shared folder permissions, emergency access settings, and certain custom fields may not export into a standard CSV file. If you rely on file attachments in LastPass, download and save them separately before closing your account or deleting your old vault.
Tip: Migration is not just a technical chore. It is also a good opportunity to clean up old accounts, remove duplicates, and replace weak or reused passwords once your data is safely in 1Password.
Step 1: Prepare Your 1Password Account
If you have not already done so, create and set up your 1Password account first. Sign in and make sure you can access your vault from the device you plan to use for the migration. It is best to perform the import on a trusted computer rather than a shared or public machine.
Before importing, decide where the LastPass data should go. You can import into your main private vault, or create a separate vault such as “LastPass Import”. Creating a temporary import vault can make review easier because all imported items are grouped together. After you confirm everything looks correct, you can move items into your preferred vaults.
- Use a trusted computer: Avoid public or work shared devices unless you control them.
- Update your browser: This helps prevent export or download issues.
- Enable two factor authentication: Protect both your LastPass and 1Password accounts during the transition.
- Create a separate import vault: Optional, but useful for reviewing imported items.
Step 2: Export Your Vault From LastPass
To move your data, you need to export it from LastPass. The common method is exporting a CSV file, which is a plain text spreadsheet style file. This file can be read by 1Password during import.
- Sign in to your LastPass account from a trusted browser.
- Open your vault.
- Look for Advanced Options or an export option in the account menu.
- Select Export.
- Confirm your LastPass master password if prompted.
- Save the exported CSV file to a temporary location, such as your desktop or downloads folder.
Depending on your browser and LastPass version, the export may download as a file or display in a browser tab. If it appears in a tab, carefully copy the contents into a plain text file and save it with a .csv extension. Do not save it as a rich text document, because formatting can break the import.
Important: A CSV export is not encrypted. Anyone who can open that file can read your passwords. Do not email it to yourself, upload it to cloud storage, or leave it sitting on your computer longer than necessary.
Step 3: Import the CSV File Into 1Password
Next, sign in to your 1Password account. In many cases, the easiest route is through the 1Password web app. Look for an import option in your account or vault settings. Choose LastPass as the source if available, then upload the CSV file you exported.
The general process looks like this:
- Open 1Password and sign in.
- Go to the vault where you want to import the items.
- Find the Import tool.
- Select LastPass or CSV as the import format.
- Upload your LastPass CSV file.
- Review the preview or mapping options if 1Password shows them.
- Start the import and wait for it to finish.
If 1Password asks you to map columns, match fields carefully. For example, LastPass may label website addresses as url, while 1Password may label them as website. Usernames, passwords, notes, and folder names should be matched to the closest available fields.
Step 4: Verify That Nothing Important Is Missing
Do not delete your LastPass account immediately after the import. First, spend time comparing your old and new vaults. Start with the number of items. If LastPass shows 800 entries and 1Password imports only 600, investigate before moving on. Some entries may be duplicates or unsupported item types, but you should understand the difference.
Check a sample from each category:
- Website logins: Confirm usernames, passwords, and URLs are present.
- Secure notes: Open several notes and check their full contents.
- Credit cards: Confirm card numbers, expiration dates, and billing details.
- Identities: Review names, addresses, phone numbers, and email addresses.
- Folders or groups: Make sure organization was preserved or can be recreated.
Then test real logins. Visit a few important websites, such as your email account, bank, cloud storage, and social media accounts. Use 1Password to fill the login details. If it works, you can be more confident that the import succeeded.
Step 5: Clean Up Duplicates and Weak Passwords
Migrations often reveal a messy truth: most people have more stale logins than they realize. After importing, use 1Password’s security and password health features to find weak, reused, or compromised passwords. This is especially valuable if you have used the same password on multiple sites in the past.
You do not need to fix everything in one sitting. Start with your highest value accounts:
- Email accounts
- Banking and payment services
- Cloud storage
- Work accounts
- Social media accounts
- Shopping accounts with saved payment cards
For each important account, sign in, generate a new strong password with 1Password, save it, and confirm that autofill works afterward. This turns the migration into a security upgrade rather than a simple copy and paste job.
Step 6: Securely Delete the Export File
Once you are satisfied that your data has transferred successfully, remove the CSV export from your computer. This step is essential because the file contains readable passwords. Delete it from the folder where it was saved, then empty your trash or recycle bin.
If your operating system offers a secure delete option, use it. Also check common locations such as downloads, desktop, recent files, and any backup or sync folder. If you accidentally saved the CSV to a cloud synced folder, delete it from the cloud service as well and clear deleted items if possible.
Common Problems and How to Fix Them
The CSV file will not import. Make sure it has a .csv extension and was not saved as a spreadsheet with altered formatting. If you opened it in Excel or another spreadsheet app, the file may have changed. Export again from LastPass and try importing the fresh copy.
Some fields look misplaced. This usually means the column mapping was incorrect or the CSV was modified. Try importing again and review the mapping step carefully.
Secure notes are incomplete. Some custom formatting or unusual fields may not transfer cleanly. Keep LastPass accessible until you manually copy any missing details.
Attachments are missing. Standard CSV exports generally do not include attachments. Download those files separately from LastPass and store them securely in 1Password if your plan and item type support it.
Final Checklist Before Leaving LastPass
- Confirm your item count is reasonable in 1Password.
- Test logins for your most important accounts.
- Manually move any missing notes or attachments.
- Delete the unencrypted CSV export.
- Turn on two factor authentication for 1Password.
- Keep LastPass available briefly until you are fully confident.
Importing passwords from LastPass to 1Password does not have to be stressful. The key is to treat the export file carefully, verify your data before deleting anything, and use the move as a chance to strengthen your online security. With a careful process, you can switch password managers without losing your data or exposing it along the way.
