<i>It would be easy enough to create a simple script that could copy it to
your clipboard and then clear the clipboard after a time delay.</i><p>pass [0] (see comment above [1]) claims to do that:<p><pre><code>  show [ --clip, -c ] pass-name
       Decrypt and print a password named pass-name. If --clip or -c is specified,
       do not print the password but instead copy the first line to the clipboard
       using xclip(1) and then restore the clip‐board after 45 (or
       PASSWORD_STORE_CLIP_TIME) seconds.
</code></pre>
