My wife's grandmother is in her late 70's. She is having a hard time managing her passwords. She uses Windows 7 by the way and also has an ipad 2. She doesn't use IE. Something she likes better the MSN browser (yeah I know).
How can I help her out and make managing passwords on both her Windows computer and ipad easier for her?
I would just give her a real life paper notepad and let her write them down on that. A lot of times, at least in my experience, older people want their computers and devices to be as simple as possible, I mean really Barney style, and pen and paper is something she'll understand a lot better than trying to get to a password manager program that's installed on the computer or iPad she can't remember the password to.
From what it sounds like, your wife's grandma is more tech savvy than my mother. And if my mom can figure out Dashlane, I think anyone can. (Mind you, I got my mom an iPod for Christmas a couple years back. The following Christmas, she asked me for 3 hours of tech support because she couldn't figure out how to set it up...sigh).
Pretty happy with LastPass myself on the desktop. It's not free on mobile devices though but a trial (at least on WP7 and Android, not sure on iOS), and not from personal experience but I've read in multiple places that it's pretty bad on iOS.
I highly recommend SplashID Safe because it a user-friendly app. Aside from password management, it also serves as a virtual safe for unlimited types of confidential records - which is greatly beneficial to her as handy reference all the time.
I vote for a real notepad too, no need to remember anything or do backups. I cringe every time somebody forgets the passwords or loses them because their computer crashed (especially those on documents, I think there's a special place in hell for whoever sets excel passwords).
