There is one legacy system that we use where the Paste function is disabled. Worse, this particular legacy system times out after 15 minutes and requires that the password be reentered. This means that I have to have my secure 14-random-character administrator password in clear text in a Notepad window so that I can type it in manually.
Crazy. Absolutely bonkers. And did I mention annoying?
If it's web based can you raise this as an issue with IT security and suggest they get a browser extension installed that blocks "no paste"?
