It's bad UX to ask users to sign something without interaction nor explanation
Discussion
What kind of situations to you come upon such a thing? 🤔
Clients seem to like to do this a lot. Most people probably just allow it forever and forget because that's the intended user behavior. Signing timestamps for notifications in Primal, the old Iris, and I seem to recall some odd ones popping up in Snort, but I'm going from memory.
depends
(Cop out answer 😂)
User: "tell me how and why in 10 words or less"
It's the old "i accept" Button next to each EULA and web2/cookie-factory.
Users have experienced daily training to find and press that button since before win95 :'-)
