False alert on reused passwords

Hello @mzel!

They show twice - once in the Login category and once in the Passwords category.

This is correct. What you are seeing here Watchtower identifying that item in the Password category as a reused password. If the Login item is holding all the correct information including the password, you can archive or delete the matching Password category item to remove that particular entry from Watchtower > Reused Password category.

Also, I remember some old discussion about automation of the search for the duplicate entries. Has there been any progress in that regard?

Currently, a remove duplicate tool is available in version 7 of 1Password for Mac. This tool searches for and removes only exact matches. On other platforms such as Windows, this tool does not exist and the removal of duplicate entries will need to be handled as a manual process.

Thanks and let us know if you need anything else! :)
