Before going through that process again, it would make sense to spend some time to figure out why you are getting duplicates to begin with.
Could you please answer the following?
-
On September 3 (the day that you imported the files BWkeep.csv and Conditioned.csv according to my instructions in the previous thread), do you recall whether you imported each file only once, or is it possible that you perhaps repeated the import process because you weren’t sure it had worked the first time?
-
Since the import of BWkeep.csv and Conditioned.csv on September 3, have you ever used the import function in Bitwarden again, for any purpose? For example, did you do a new import after installing the desktop app or after installing the browser extensions?
-
In the browser extension, if you go to
Settings > Options, is the checkbox to the right of the “Ask to add login” option checked (
) or unchecked (
)? -
Just as a sanity check, what is the evidence you have for making the claim that there are a “huge number of duplicates” in your vault? Can you post some screenshots that show this, after sanitizing sensitive information?
