Importing passwords into 1Password nothing but a headache. Don't do it. Start completely fresh.

You're right that 1Password doesn't provide a good workflow for initial import and cleaning up the imported entries. That's something that can be improved and something that might prevent potential customers from making a switch from their old password manager.

My personal workflow for doing this was like this:

• I imported from my previous password manager (PasswordSafe) and Chrome into separate vaults
• most entries had duplicates - one older from PasswordSafe but with more secondary info, one more recent (Chrome) with current passwords
• I created a vault called "cleaned up items"
• I created a view that included the two import vaults but not the "cleaned up items" vault
• I changed to the "all objects" category in that view, so all imported, but not cleaned up items were shown
• sorted the "all objects" view by title
• I took the first item of that list and copied the password, then searched for entries with the same password. If there were duplicates, I merged them, tried to login to the corresponding website, and finally moved the cleaned up item to the vault for cleaned up items
• the same for items with different passwords but for the same site (most of them appeared next to each other due to the sorting by title)
• repeat with the new first item

This way, the list of items to clean did get shorter and shorter until I processed them all. Then I moved all items from the "cleaned up items" vault to the personal vault, deleted the 2 now empty import vaults, and that was it.
