A very straightforward pass extension with fuzzy search for Ulauncher.

To install, go to "Ulauncher preferences", click "Extensions", then "Add extension" and paste the URL https://github.com/jonhoo/ulauncher-pass. You can also check out the repository manually into ~/.local/share/ulauncher/extensions if you want to make modifications yourself.

Once the extension is installed, you can pull up passwords by typing pass followed by a search string (you can configure this prefix). The search string is fuzzy-matched against all the passwords stored in ~/.password-store, so you usually only need to type a few of the letters to get a match. Selecting an entry copies the stored password to your clipboard. That's all!
