I wrote about Digits, Twitter's attempt to end the practice of logging into mobile apps with a password. Instead, you'll use your phone number — which Twitter says is vastly more secure.
Most people use the same passwords repeatedly, and use passwords that are relatively easy to guess. And many buzzy new apps aren’t backed by strong security practices. Twitter says it is bringing everything it has learned about security since its founding to Digits. "Passwords just suck," Ducker says. "I go to dinner parties and people say, 'Oh, you work in tech? Can you get rid of the password?' And we’re finally getting rid of the password, for the vast majority of use cases."
