Access to the account up to 2 devices, in cases of violation - no guarantee is provided.
Do not transfer data to others (only to the end user) and do not log into the account for verification - as the system determines the number of logins and the account can be blocked.

According to CapCut's official documentation regarding login lockouts caused by "unusual login attempts" (like repeated incorrect passwords), here is what they recommend doing instead of changing your IP or resetting your password:

Wait exactly 24 hours: The official documentation states that this is a backend security cooldown. You must wait a full 24 hours from your first failed attempt. Do not attempt to log in during this window, as repeatedly trying can reset the timer and extend your lockout. You can verify this worked if the error message disappears when you log in tomorrow.

Sync your PC's clock: CapCut's authentication tokens can fail and trigger security lockouts if your computer's time is slightly out of sync. On Windows, go to Settings > Time & Language and ensure "Set time automatically" is turned ON. You can verify this by checking if your Windows taskbar time perfectly matches the current time on your phone.

Sign out and Restart: Fully close the CapCut desktop app and restart your PC to clear any cached login credentials that might be stuck in a failure loop.

Do not create a new account: The official guide explicitly warns against trying to bypass this by creating a second account, as it violates their terms and can lead to a permanent ban on your device.

Contact Support: If the error still appears after 24 hours, CapCut advises contacting their support team through the official help center. They ask that you provide your login method, your region, and a screenshot of the error.
