Q&A for How to Change Your Password in Yahoo

If your phone number was registered in your account, then you can request to reset your password by sending a code to your phone via text message.

If you don't have access to the recovery methods associated with your account, you cannot reset the password. There is no way around this, and Yahoo! cannot provide help over the phone.

Yes, you can. You should be given the option to save your credentials when logging in.

You can't, they do this for security reasons. If it is really vital, then you might be able to contact support, but you probably will have to wait 12 hours.

In order to add or change a phone number, you'll need to be able to log in to your account. Log into the Yahoo! homepage, then open your Account Info page (see the first method). Click "Account security," then click "Phone numbers." Enter the phone number you want to use, then enter the code you receive via text to confirm it. You cannot change or edit the phone number if you don't know your password.
