Passwords were a good idea in the early days of computing, when we only had to remember a few passwords. However, passwords don’t work as well in the Internet era, when we have dozens of separate online accounts.

People cope with the sheer number of passwords they have in several ways. Unfortunately, the most common approach is to reuse passwords, which is risky as the loss of one password for one account might result into the loss of multiple accounts.

Don’t reuse passwords and change your passwords regularly. Make them complex. That means using a combination of at least a dozen letters, numbers, and symbols. A password management application, such as Dashlane, can store these complex passwords, so you don’t need to worry about remembering them.
