Which account is asking you to sign in?
This catalog does not require an account for browsing or a local watchlist. A separate viewing service can have its own login, and an existing Loklok-named application can have another. Start with the name and address shown on the sign-in screen. A familiar logo does not make passwords, saved lists or subscriptions transferable between different services.
Recover the original sign-in method
Check whether you originally used an email, phone number or a third-party sign-in button. Another method may open an empty account rather than recover the old one. Use the recovery process attached to the service, check the entered address and avoid sharing one-time codes. If an app changed names, look for publisher documentation instead of assuming a comment describes your particular account.
VIP codes, renewal and cancellation
Locate the purchase receipt to find where the subscription is managed. An app-store purchase and a web purchase may have different cancellation steps. This site does not sell VIP plans or issue codes for other apps. Claims such as premium unlocked or no ads in a modified package are not benefits supplied by this browser catalog.
An empty My List is a different issue. Check the browser, private mode and website storage, then restore a backup if you have one. Do not reset an unrelated account to repair local browser storage.
