- User Control- You are in control of the chats you want to lock and you are in control of whether to use PIN, pattern or fingerprint. This provides you with flexibility and openness.
- Careful of the dangers to be considered.
- Third-Party APK Downloads – In case you download the APK to unofficial sites, you may install a modified application that might have spyware or malware.
- Permissions Misuse – The app tends to seek permissions such as permissions to use the data, overlay permissions, and biometric permissions. When in the wrong hands, they may reveal your information.
- Data Privacy Issues -Although most of them do not scan your chats, some poorly created or fake versions attempt to intercept private data.
- Compatibility Problems – Once a WhatsApp update takes place, the locker app will cease to function correctly and will result in crashes or locks being bypassed.
- Not Endorsed by WhatsApp – As WhatsApp does not officially support these apps, it is always a possibility that they will either become unreliable or outdated.
✅ How to Use It Safely

Nevertheless, as it is the case with any third-party apps, there are risks involved.
