What is the CapCut Security Notice?
The Security Notice appears when CapCut detects something unusual with your account, device, or app version.
This is CapCut’s way of protecting you from potential account breaches, corrupted app files, or unsafe software.
Common triggers include:
- Outdated app version
- Installed from unofficial sources (APK sites, modded builds)
- Unstable or restricted internet connection
- Login from unusual locations or devices
- Temporary app conflicts with other software
Signs you might see before the Security Notice appears
You may notice subtle hints before the error shows up, such as:
- Slower app loading times
- Certain buttons or features becoming unresponsive
- Difficulty logging in
- Sync issues with your drafts or cloud storage
Catching these early might help you fix the problem before it fully blocks you.
Why you should fix it immediately?
- Protect your account from unauthorized access
- Prevent losing unsaved projects
- Regain full access to all CapCut features
- Avoid editing interruptions during deadlines or client work
Step-by-Step fixes for the CapCut Security Notice
1. Check your Internet Connection
A weak or unstable internet connection can confuse CapCut’s security verification.
- Switch between Wi-Fi and mobile data.
- Restart your router if using a home network.
- Disable VPNs or proxies, as they may trigger the warning.
Tip: Use a stable, high-speed connection when logging in after updates.
2. Update CapCut from the Official Store
The most common fix.
- Go to the Google Play Store or Apple App Store.
- Search for “CapCut” and tap Update.
- If no update is available but you still see the notice, uninstall and reinstall from the official store.
Avoid APK sites — installing from unofficial sources is a major cause of this warning.
3. Grant full app permissions
CapCut may fail its security check if it can’t access necessary device functions.
On Android & iOS:
- Go to Settings → Apps → CapCut → Permissions.
- Enable permissions for storage, camera, microphone, and network access.
On PC/Mac:
- Ensure CapCut has network access through your firewall or antivirus settings.
4. Clear cache or offload storage
Sometimes, old or corrupted cache files cause verification failures.
On Android:
- Settings → Apps → CapCut → Storage → Clear Cache.
On iOS:
- Settings → General → iPhone Storage → CapCut → Offload App.
This resets the app without deleting your drafts (unless you clear data).
5. Backup projects before reinstalling
If you must reinstall CapCut, save your work first.
- Export important drafts as finished videos.
- Sync projects to CapCut Cloud (requires login).
- Copy exported files to another storage location.
6. Reinstall CapCut
When other fixes fail:
- Backup drafts.
- Uninstall CapCut.
- Reinstall from the official app store.
Most persistent security notices disappear after a clean install.
7. What NOT to do when you see the Security Notice
- Don’t try modded APKs or cracked versions to bypass it.
- Don’t repeatedly log in on multiple devices in a short time.
- Don’t ignore the warning — it won’t disappear on its own.
Device-Specific fixes
For Android:
- Clear cache/data from App Settings.
- Ensure “Background Data” is enabled.
For iPhone/iPad:
- Enable “Background App Refresh” in CapCut’s settings.
- Offload and reinstall if needed.
For PC/Mac:
- Download the latest version from CapCut’s official site.
- Disable strict firewall rules that may block app verification.
