Managing devices

I think it's under your account overview on the dtv stream website. 

It's not though. Where exactly. I've looked everywhere 

Screen shot?
I only see 
Total balance, my TV subscription,see what's on TV, get support, manage my cloud dvr

Nothing that says manage devices 

Try resetting your password is what I read when doing a google search.

Yeah. I reset it but it still automatically signs in on all of my devices 

U can also talk to live chat support and they can delete the devices for you.
