Every year at RootsTech the password problem is front and center. People go to a booth and try to sign up for a new partner product that uses their FamilySearch account, etc but they can't remember their login and password for FamilySearch so they can't enable the new product to access their information. Worse, they don't know how to login to their email when they're not in front of their home computer, so they can't use the site's password reset or retrieval option. Nothing is more frustrating than being at a world-class conference and not being able to take advantage of the specials and offerings.
If you have issues remembering your passwords, here are some sites that will help you. These sites allow you to sync your password list across multiple devices (some only do this with paid versions). So if you show up at a Genealogy Convention needing access to some obscure account, you'll have it ready and waiting on your phone!
