#infosec annoyance of the day - I use a tool for work that requires me to put in a rolling one-time code for 2fa, and doesn't show the code as I'm typing it.
That would be ok, except if I switch apps to copy the code so I can paste it in, it usually forces me to re-enter my username and password, then even though I'm in the 30 second validity window, it refuses the code.
So I have to wait till the 30 seconds roll over, copy the code, switch to the tool, re-enter my username/password, hope it doesn't take so long to negotiate with the back end that the code in my clipboard expires, then finally paste the code.
Conveniently I only have to do it multiple times a day, every work day.
