Are you able to access your email account,after you change the password? because you said that you get the message about incorrect password ***** 24 hrs of changing your password.
So you don't have the phone with the number which end with 63?
I am not trying to call you I just wanted to know if you have the phone associated with your yahoo mail or not?
The number ends with 63
As you do not have the phone with you it will be little difficult to reset the password. You have to call this number *********** and verify your identity to the agent and they will help you to reset the password.
Please let me know, if you need any further help, otherwise please remember to give positive rating below, as that is the only way I am compensated for my time and effort.
OK, there is another way and it is also a long way, first you have to contact Yahoo and they will send a reference number on your other email address along with another phone number, you have to call that number and follow the instructions.
Here is the link, where you will find the step by step instructions to contact Yahoo.Hopefully, you will recover your Yahoo email password ***** few hours.
