Proton Pass currently lacks a native feature to identify and manage duplicate entries, which is a significant pain point for vault hygiene. Especially after importing data from other managers, users often end up with redundant items that must be manually found and deleted. I propose the implementation of a Duplicate Detection tool that scans the vault for identical URLs and usernames. Beyond simple deletion, a "Merge" function is essential to consolidate different notes or historical data from duplicates into a single primary entry. Adding this capability would greatly improve the user experience and help keep the vault organized and clutter-free as the database grows.
