Have a read of this link below about changing your password and force a logout of all devices.
Apparently a couple of people have reported the forced logout option is not available anymore (assuming it's a glitch or bug NOW end) after changing your password.
If that's the case and you can't force a logout of all devices by following the instructions in the above link, then see if NOW live chat can force a logout of all devices on your list their end.
Use the green chat online button from this link page below to start a web chat with NOW.
Unfortunately they removed the option for up to be able to remove a single device you just have to either speak to someone from nowtv customer services and they can do it (annoying having to speak to them just todo that) or change your password but it then logs all devices out which is a pain, unless it's to kick someone off that has your details, it's absolutely ridiculous they should of left the option there for us todo it as it is our account and we should have access to it
When did Now allegedly remove that option?
I’ve been using Now for years, and it’s always been all or nothing in my experience,
Yes, you used to have a limit of six devices and three swaps a month, but it was never effective as a way of removing unwanted users with a persistent login.
You could remove users with a non-persistent login by changing your password, but you can still do that.
Even back then, you needed to force all users off at a password change to get rid of the cling-ons.
That’s changed a little now; you can selectively remove users service by service, but as you can’t tell which service they might be using, it’s still not much use.
The other downside to the new arrangement is that it doesn’t work at all 😢; but Now are now aware of this, and we might hope to see a fix by 2025.
The number of swaps is now unlimited, by the way.
