It seems like every other day there is a new website or service that you have to sign up for and create a new account.
And it is hard to remember of all your passwords. It is even hard to remember all the sites you signed up.
The simple solution for this problem is to use Password Keeper.
Password Keeper allows you to save all your passwords in a secure database, encripted with your master-password.
And your master-password is the only one password you need to remember.
If you forget your master-password, you would not be able to open your password database. Password Keeper developers would not help you.
If you remove your Password Keeper, your password database would be removed also. That is why you need to create backup from time to time.
