1) Can the older folks actually remember all their passwords? Or are they writing them down?
2) On a related note, if they only have one or two passwords to remember (email and maybe something else) that's easier than younger more tech-savvy individuals who may be trying to remember MANY MANY passwords (email 1, email 2, bank account 1, bank account 2, social media website 1, 2, 3, online forum 1, 2, brokerage 1, 2, iTunes Store, Amazon, Ebay, some app, electricity bill, wireless plan, phone plan, credit card 1, 2 ,3, etc, etc, etc).
I am by no means young, I'm 31, but am part of a more tech savvy generation. I have so many passwords to remember, even after trying to keep them the same, that now I have a whole Gmail label called login info where I store my passwords for everything. Not the actual password but mnemonics that are relevant to me like :"firsthousenum+first name first crush, no space or caps" which would be the street address (house number ) of my first house and the first name of the first girl I had a crush on, with no spaces or Capital letters. That is just an illustrative example, they're actually more obscure.
And this is after I made a concentrated effort to have categories of passwords, like all financial ones (bank, credit card, brokerage, etc) would be the same, but different systems have different requirements (letters, capitals, numbers, special characters, length) that it didn't work out, plus some force you to change passwords periodically, it's a mess.
On a different but kind of password related note, I wish that there would be a concept of a temporary password to use for accounts. For instance, I recently travelled abroad for a week, and was worried about key loggers or some other stuff getting my gmail password when I log on in hotels, cafes, other people's houses. What I would've loved is to set up a temporary Gmail password that was only valid for 1 week (in addition to my normal one) and use that while traveling. The temporary password would have limited access, I could send and read emails, but not change any account settings (like passwords, etc.) That would've been fantastic.
Instead, I changed my Gmail password to another one, but now that I'm back, Gmail won't let me change my password back to the original one (as previous passwords can't be reused). This is something new as I'd done this before while traveling.
