Can't get into my yahoo.mail. forgot password.

Hello, I am having a problem with my yahoo. mail. I have tried to get a code from you all as I have forgotten my password. When i get the text to my cell phone and go to yahoo that needs the code it is gone... Can you send me a code here so I can change my password. they sent
me 2 but neither one worked because where you type the code in was gone. Thank you Janet Sampson. :)
