PartySync is your timer account: one Discord login for the desktop app and this site — same look as the ticket dashboard, one place to manage profiles, cloud sync, and friends after you sign in.
Your run profile (name, splits) and personal bests are stored in the cloud with that account, alongside your friend list and Twitch links.
From the app: Account → Open login in browser signs you in and syncs automatically.
Use Log in with Discord above, or open the Discord sign-in page directly.
Multiplayer sync uses WebSocket /speedrun/ws from the desktop app (authenticated by your session there).
