Duplicate Password Remover for Bitwarden

Bitwarden is an awesome, cross platform, password manager and generator. With a free account you are able to sync your passwords between your computers regardless of the operating system they are running. On a mobile device? No worries! Bitwarden will also sync your password to that device as well. Overall it is a great little tool to keep your passwords organized and protected. After using it for about a year, the only I really do not like about it is its inability delete, or even view duplicate passwords. After reading through part of Reddit where users were suggesting that I block out a part of my day to import the passwords and secure notes to excel and manually delete passwords that way I decided that there had to be a better option…..

After 10 minutes of DuckDuckGoing (It will catch on just wait) I was able to create a python script that takes the exported Bitwarden Vault as a Comma Separated Values File (CSV) as an input and exports it to a new CSV with the duplicates removed.

To run the code you will need to install python as well as the pandas plugin.

Steps:
1. Export from Bitwarden and Rename

  • First we are going to export our Bitwarden Vault to a CSV. This can be done by opening Bitwarden and going to —> File —> Export Vault.
  • Select.CSV when it asks for file format.
  • Enter your password and download the file.
  • Make a copy of the the exported .CSV file and name it to bitwarden.csv.

2. Download the Python Script and Configure Dependenices

duplicatefinder.py

The code for the duplicate finder is shown below:

import pandas as pd
df = pd.read_csv('bitwarden.csv', usecols=['folder', 'favorite', 'type', 'name', 'notes', 'fields', 'login_uri', 'login_username', 'login_password', 'login_totp' ]).drop_duplicates(keep='first').reset_index()
file_name = "bitwarden_deduped.csv"
df.to_csv(file_name, index=False) # you don't need to set sep in this because to_csv makes it comma delimited.

3. Run the script!

  • Simply run the script by navigating to the directory where you downloaded it and run python duplicatefinder.py.

4. Re-Upload Bitwarden Vault

  • After the script is run there should be a file called bitwarden_deduped.csv.
  • Open up this CSV file in the editor of your choice and check to make sure your important logins, secure notes, etc are still present and not duplicated.
  • If everything looks good it is time to re-upload.
  • Navigate to your Bitwarden Webvault (typically, Bitwarden Web Vault).
  • Verify one last time that all modfications made by the script are valid and that you are not missing any important passwords, secure notes, etc.
  • Click Settings at the top of the screen and then scroll to the bottom.

Congratulations!
All of your logins and notes should now be de-duplicated and should sync across your devices shortly! Hopefully this saves you some time so you can get back to doing what you do best!
