How to change yahoo password

Hello,
I would like to change my yahoo.com e-mail password. Every time I select change password it routs me to ATT. I have not been an ATT customer for donkey years. I just want to change the password used to access my e-mail. What do I need to do. please provide actual URL not just click this nonexistent button. my e-mail address is ***@***

Thanks
