Importing from LastPass - Duplicates

nearly 5 years and still they have not added this function, crazy!!!
I just imported from lastpass, didn’t work, nothing was imported
imported again, didn’t work
imported a 3rd time and now it has duplicated everything 3 times.
I now have over 100 folders and 3600 records… and no way to fix it.

This is a known LastPass bug that creates duplicates, triplicates and more when exporting. You need to log out of LastPass, close the browser, restart the browser, log back in to LastPass, and then do your export.

You can the start over with your clean CSV file after purging your Bitwarden vault. To purge, log in to the Web Vault, click your profile icon (in the top right) and go to My Account, then scroll down to the “Danger Zone” and click Purge Vault.

Did you refresh the page after you imported the first and second time? My guess is that the import worked, and you got impatient. Thus, you repeated the process three times and got exactly what you asked Bitwarden to do.

Your best bet now is to just clear all the contents of your vault and start again. This time, import, wait a bit, then refresh your client to see if it appears. If not, wait a minute and refresh again.

Nope the issue was bitwarden. Nothing is duplicated in the lastpass csv.
It did not show the imported data after doing the import, not even after refreshing.
It didn’t showing anything until the 3rd attempt.
I purged everything, then did it again, then i had to log out out and login again to see the imported data.

No i was not impatient.

A note for future users - I don’t believe there is a bug in the import process, as is witnessed in @Russ_Michaels experience. If you perform the import process and it says it was sucessful, then it worked. And if you repeat the process three times, you will get three copies of the same import added to your Bitwarden vault in the cloud. However, the interface can be slow to sync these changes to your device sometimes, and it may appear that the import is absent. While the absence of feedback to the user regarding the slow sync is less than ideal, please just be patient and keep checking - it will eventually sync to your device and the imported data will appear. If you have a lot of records to import, this process will also may take longer than a small import. :+1:

You really need to put a notification on screen after the import is done to say this.
Assuming the delay is the cause, it took over 10 minutes for my import to show.


I browsed around for import and duplicates and a few variations, and didn’t find anything.

My lastpass export, followed by BW import, “worked” without error messages, but I now have two copies of every item. The contents of the items I hand checked looked OK, other than being duplicated. I checked the csv with a text editor, and don’t see duplicates. I’m a newbie, import is my first BW task, so perhaps I made that newbie mistake. Tried thrice, wiping out the vault after each time (third time using chrome), and all three times it duplicated everything. (win10, BW 2.25.1, web vault interface, safari browser 96.0.2, lastpass 4.88.0)

My lastpass vault has around 2000 password entries; total csv size of about 160k.

Suggestions appreciated.

Well, I guess that’s it for me. If I can’t import, clearly I need to look elsewhere. Sounds like a great project, good luck.

This is happening to me too. First import duplicated everything. Purged. Second import tripled. Purged. 3rd import created 4 copies of everything.

I’ve researched quite a bit, and I’m amazed how this is not focused down. How do they plan to acquire new customers if imports work like crap? Only focusing on non-password saving customers?

I’m seeing this too but I think its an issue with LastPass. I noticed the duplicated entries within the export csv that LastPass produces

I ended up fairly painstakingly deduping the csv manually and then importing which worked perfectly

It’s a LastPass problem.

I checked the CSV file download and my entries were in triplicate!

All I did was copy the first cell and did a search and deleted everything below the next find. Hope this makes sense? Saved the CSV and then imported it into bitwarden, I also deleted the groups column!

At any rate, all entries were correctly imported.

I confirm the problem. LastPass export contains duplicates and they are scattered all over the file. If you have multiline secret notes then deduplication is quite tricky.
I tried export using Chrome Extension and via LastPass webpage. Both times there were many duplicates.

To solve the problem I did Web Vault Export using Incognito Chrome. Then the file was rendered in a browser and it didn’t contain any duplicates.

Yes, the bug seems to be that if you export multiple times in LastPass in the same LastPass login/browser session, it ends up duplicating the content. This was reported on the LastPass forum here Solved: Re: Export has duplicate entries - GoTo Community

So you can try logging out and restarting the browser, then exporting again.

WOW Yes you are correct. There is a bug in the LastPass export.
I am using the LP Firefox addon (released 20 Dec 2022) and the bug is still there. I had never noticed it before because I only ever export once per session, but now I do a 2nd export it has (obvious) duplicates.

Sadly the Lastpass csv file import appears to be broken. After import there appears to be many duplicate entries in the Bitwarden vault. No amount of closing/rebooting/recreating the csv in Lastpass helps. Oddly, I cannot find the duplicate entries in the csv file that Lastpass has created.

Surely somebody must have solved this.


Hello @Basjoe - Did you refresh your vault after importing, or did you repeat the import process again? Each time you repeat the import you will create a duplicate set of credentials in your vault.

Thanks for the reply.

Success !. Before attempting a second or subsequent import of a csv file it appears to be imperative to go to Account Settings/My Account/Danger Zone and Purge Vault. I did this twice for good luck because it appeared some folder names stayed put the first time, but they were deleted the second time.

I’ve created a Free Organisation with two collections, one for me, and one for my wife. (Sadly Bitwarden has no equivalent of Lastpass’s Identities). So now I must go through over a thousand entries sorting them into the correct Collection. That’s going to take some time !

Best Regards

Glad you got it sorted. And yes, Bitwarden and LastPass are quite different - I was on LastPass before switching to Bitwarden, and it has always been my impression that LastPass is very focused on implementing lots of nifty features, whereas Bitwarden is very focused on keeping things simple and secure. Hope it works out for you!

I will say, while there are definitely some nice-to-have features that are more niche when it comes to some other password managers such as LastPass or 1Password to name a few. I personally would much rather a password manager focus on security of their product and prioritize security above all else before adding features if that comes at a cost to security.

Bitwarden definitely seemed to fit the bill for me when I was looking around, and while they are always looking to add new features and better the user experience I’ve personally never had any real shortcomings when it comes to useage. Maybe it’s just me not having much experience with other password managers (coming from KeePass a cloud service with sharing was already a step up) but overall having a password manager makes my life more productive, less stressful with forgotten password and generation, and keeps me better secure online.

Definitely a bit of a learning curve to understand how Bitwarden operates yes. It is always nice to see they are looking to constantly better the product for their users. Overall though if security is your main concern so far Bitwarden has far exceeded my expectations.
