Yahoo's plan for reinventing passwords

Yahoo email users will have a new way to login in to their accounts that will no longer require them to remember a traditional password.

The tech giant introduced on-demand passwords, where users can have new passwords sent to them via text message every time they need to log in and check out their inbox.

The service is optional, so users interested in on-demand passwords go to Settings, then Security to set it up.

Yahoo's password option works similarly to two-factor authentication, a second layer of protection for accounts where users type in a numeric code as well as their password to sign in to accounts. Codes are usually sent as a text message to the user's mobile phone. Services including Google's Gmail, Facebook and Twitter all offer two-factor authentication.
On-demand passwords are available now to Yahoo email users in the U.S.
