"This account is open on another device"
Why TuneUP signs you out on one PC when you sign in on another, and how to manage devices.
Why it happens
A TuneUP account is active on one Windows device at a time. When you sign in on a second PC, the first one shows this message and signs out.
What to do
- To keep using this PC, sign in again here. The other device is then signed out.
- To sign out every app device at once, open your profile on the website, go to Quick Settings and use Sign out app devices. Your website session stays active.
Seeing it unexpectedly?
If you don't recognise the other device, change your password, use Sign out app devices, and turn on two-factor authentication in your profile.
