"3. Use a password manager
The concept is straightforward: You sign up for a service that generates and stores a unique, strong password for each of the websites where you need log-in credentials. You can do that yourself if you have a savant-like memory for numbers, but in all likelihood you don’t. Then, you just need to remember one, excellent password in order to access the service. Yes, you may ask, but what if the password manager gets hacked? Not to worry, says Chris Soghoian. “Password managers encrypt their data, so these services are safe. And, ultimately, in 2015 it’s not a good idea to use the same password for more than one website. That effectively means that you have to outsource the task.” Guido does worry about hackers, but he agrees that a password manager is a vital security tool. He employs a service called 1Password and stores the data solely on his own laptop—he doesn't activate the option that allows users to sync 1Password with other devices through DropBox or iCloud."
