But regardless of how the list had been lost, I was screwed.
Like the slow spread of a nasty disease, my password collection had morphed from a manageable handful a few years ago to a long and meandering list that enabled me access to just about every level I functioned on.
As the day progressed and I kept finding myself unable to do even the most simple tasks at work, I truly began to see my life for what it was: me, a hard drive ... and my passwords.
Although the process is slow, I am on my way to re-establishing my online life through a methodical approach that goes like this:
Enter every statistical combination of my date of birth, first address, pet's name, mother's maiden name and ex-boyfriend's favourite meal.
Stab wildly at the keys in the hope some deep-brain motor memory will see my fingers tap in the right combination.
Enter one of many email addresses into each website in the hope it has a good password-recovery system, and if that fails ...
Actually speak to a human (desperate times, desperate measures) in the hope I can reset and resave what was lost.
Each new password created is like a little life being born, an entry into a rarefied world temporarily denied to me - and valued all the more because of the loss. Like a grandmother sitting by the fire knitting a scarf, I have watched with pride as my list of new passwords has grown.
And,as a bonus, my list has undergone a makeover, a digital-life audit which has seen old replaced with new - new people, new pets and new significant dates - a password list to be proud of and one to take me into the future.
And a future that is photocopied several times, laminated, backed up and stored virtually and physically, in places that can't be found but that I can remember. I hope.
