Password keeper better than my brain

I got so many things to remember, what time to fetch my son, what time to off the gas stove, what time to feed my baby and more. Most of the time, my brain just full of what and what. Actually, this is very taxing to remember this and that, plus, i still have to remember a lot of passwords for some of my online pages which are including my mail box, my music and movie downloading page, my paid post accounts as well as my internet banking accounts. See, there are just so many passwords have to remember, forget either one will definitely lead problem to me. Undoubtedly, i need a password keeper to help me to remember these since my age is catching up as well. I know, i really have to admit this truth that i am getting old.
