Whatever you call it, cancelling the authorization, revoking access or disconnecting, there's one move that does it: remove Soco from your TikTok permissions, inside the TikTok app. Tapping Remove all access in Soco's own TikTok authorization sheet doesn't fully unlink on its own.
Unlink inside TikTok
The whole thing takes about a minute:
Open the TikTok app and switch to the account you want to unlink.
Tap the ☰ menu in the top right of your Profile.
Tap Settings and privacy.
Tap Security and permissions.
Tap Apps and services.
Find Soco and tap Unlink (or Remove access).
Check Soco no longer appears in that list. From this point Soco has no access to that TikTok account's data.
The account still shows in Soco, with a purple icon
That icon is the confirmation, not a failure: an unlinked account stays on the Soco Profile screen with a small purple warning icon next to the username, and that's how Soco signals it's fully unlinked. Soco doesn't yet have a way to remove a past account from that view; a true in-app remove option is being built but isn't out yet.
What stops after you unlink
Soco stops syncing and stops reading TikTok data for that account, so TikTok-connected features stop for it specifically. You can relink any time with Continue with TikTok in Soco.
