Worked somewhere that required security clearance that used your national insurance number (UK equivalent to SSN) as your login id. Most people in the UK do not memorise their NI number.

Password had to be uppercase and lowercase letters, numbers, and special characters, I think at least 12? Couldn’t have back to back special characters or start or end with numbers. No whole words, either.

So now you have to remember two strings of letters and numbers. Sackable offensive to write either down. I once got a phone call from security because I would miss enter my password after lunch first time around, just once a day, but they rang me up still to see what going on.

Security there was a nightmare, worked with an obviously disabled guy, who forgot to put his disabled badge on his car dashboard and they threatened to ban him from site (which would result in the sack as you couldn’t work remotely). The kicker was that they said we know you forgot to put the badge out, so they knew he was disabled as all car registrations are preregistered only way onsite.
