IBBoardHOLY FUCK, this dumb-arse payslip system (which I've been using for several years).
Me: *logs in*
System: You need to change your password every 180 days! You can't use any of your last 13 passwords!
Me: *generates new random password*
System: Thank you! You are now logged out.
Me: *logs in*
System: This is the first time that you've logged in to view payslips (or your email or password recently changed) so we need you to tell us your National Insurance Number.
Me: I wonder which of those it could be 🙄
And this is on top of the fact that they switch from proper 2FA to code-by-email about a year back 😐
