My simple response. Stop using websites and apps that prevent pasting because it implies that the website or app has no idea how to secure their website or app properly.
The web is unfortunately too ubiquitous for this approach. If I get hired by someone, I have to use the website they chose for pay stubs, or health insurance descriptions, or direct deposit configuration, or stock option distribution, or many other life-essential services that an individual has absolutely no control of. Sure I can complain to HR, but it will fall on deaf ears that were sold by a shitty SaaS pitch that made some loser’s life mildly easier in return for a subscription payment.
And that’s not even touching all of the government websites that behave in this way.
