it is not the passwords that drive me mad, it is the site protocols.
I work for a charity, who are so obsessed with security that if you do not access its client file site every few days, I still haven't worked out the exact number, but it is under a week, it invalidates your password and you have to go through a long rigmarole involving your divisional manager to get a new one. This system has lost it volunteers and I am close to packing it in as well.I have just had to bring a set of client papers on holiday with me, so that I can finish entering them on line and getting on to the next stage of an urgent claim when my next new password arrives.
Then there are sites, not the above, that send you temporary passwords that are valid for 3 hours, which again assumes you spend all your time hovering over the keyboard waiting to catch their every communication the moment it comes in.
To think that London, or anywhere else for that matter, does not belong to any one demographic
