Forgot your password? Yahoo released an on-demand sign-in option for users who cannot or do not want to remember their password. The announcement made at South By Southwest (SXSW) Sunday means anyone with a Yahoo account can request an on-demand password texted to their mobile phone.
Yahoo said the new authentication option aims to ease anxiety around having to memorize a password and improve security for users. Once a user opts-in, the next time they sign on, Yahoo sends a secure password directly to their mobile phone. The on-demand password option is available in the United States.click
It's similar to clicking the "I forgot my password" button each time you try to sign into accounts you hardly use.
