Yahoo hopes that you'll forget your password
Twitter isn't the only internet giant that wants to spare you from remembering passwords. Yahoo has just trotted out an optional login process that sends passwords on demand. Sign up and Yahoo will deliver a single-use password to your phone whenever you need to log in -- you can prevent someone from easily hijacking your account no matter what device you're on as long as your handset is nearby. This extra-secure option is only available in the US right now, but there's a good possibility that you'll see it in other countries before long.
Oh, and the end-to-end email encryption that Yahoo promised? It's still on track. The company gave its first demo of the locked down messaging system at SXSW, and it's delivering early source code for curious tinkerers. The technology still doesn't have a definite release date, but your sensitive Yahoo conversations should be safer from prying eyes by the end of the year.
