I use Lastpass and it has helped me tremendously to be more secure and able to use much stronger passwords. I tried the video's last suggestion in the past, it worked for awhile until certain websites won't let you use similar passwords again when they require them changed... making up a completely different password every few months for a financial site became really annoying. I recommend LastPass whole heartedly. I have managed in the past probably around 100 different sites passwords for myself - in a password proteced excel spreadsheet. That worked too as long as I kept it up to date, and could access when I needed to. Lastpass is available to me on my phone, tablet and PCs. Easy-Peasy!
