How to enable On-demand password feature in Yahoo! Mail
It is very difficult for a user to remember so many passwords at one time. So yahoo introduced an on demand password system to exempt users from remembering the password of their webmail account. You will have to link your phone with Yahoo mail account. Whenever you will have to login to your account, Yahoo will send you a code via SMS. You will have to enter that code in place of password to get access to your account.
Since the code will be send to you on your phone, this method is considered a safe way to log in to your account. It is said that best password is that which changes every time because you are the only one who knows it.
The possible disadvantage of the on-demand password is if a user forgets or loses phone. So you have to disable Preview SMA Messages on lock screen and use a lock code to lock your phone.

At the top of the Yahoo mail sign in page, tap on your name
