It depends on Remember me, which is ticked by default on the sign-in page:
- Ticked — you stay signed in for 7 days.
- Unticked — your session lasts 12 hours.
One sign-in covers gridcast.gg and GridCast TV together, and Logout signs you out of both.
For the desktop apps, leave Remember me ticked when they send you to the browser to sign in — they need it to stay signed in (see Software & Downloads).
