THE recent revelation that the account information of at least 500 million Yahoo users was stolen in 2014 was a big reminder that we all need to be smarter about our digital security. That includes our smartphones, which are increasingly the repositories for all sorts of information about our digital lives. Turning our smartphones into personal data fortresses requires the use of strong passwords — and never using the same password for different services. Fortunately, there are plenty of apps that can help you remember all those passwords. Dashlane, which is free to download for iOS and Android devices, is an excellent secure password system. The app, which is essentially a digital strongbox for all your online keys, has just one master password to remember. After you enter that password (which should be very strong), you have access to all your other passwords inside the app. This means people can move beyond using easy-to-remember passwords like “123456” and use longer, more complex passwords that are more difficult for hackers to crack. To help, Dashlane has a password generator that users can customize, for instance by varying the length of passwords or specifying whether they should include nonletter symbols.
