<i>&quot;I ought to at least find a better way than the clipboard, to transfer passwords from the manager app to the browser etc...&quot;</i><p>With X selection buffers, when you&#x27;re pasting data the X application you&#x27;re pasting from gets to run arbitrary code (informed of the destination!) to determine what to send.  I&#x27;ve been wanting a password manager that asks me for verification before transferring the data.
