Mike is having issues logging into Yahoo at home. It says he's using the wrong password at home, but it takes it at work. Leo says one way to test it is to type out the password in notepad and then copy and paste it in. If that works, then he'll know it's not a problem on his end. It could also be a corrupted cookie in his browser. He should try using another browser, or clear the cookies in his browser and try again.
Mike also wants to disable the password challenge on his phone. Leo says that is dangerous to do, but he can turn it off in the phone's security settings.
