They just texted me saying, "There has been several requests to reset the password for your Yahoo account. If you have requested a password reset, please reply "Yes". and then a second text, If you HAVE NOT requested a password reset, please respond with the Account Key that we have sent to your mobile device. -Yahoo Verification Services. I noticed the Account Key first and replied saying I did not request and then noticed this text message from this number which does not happen if you do request help services from Yahoo in resetting your password. Be aware of these [***] holes!
