Although Apple does not offer direct app locking, Screen Time can serve as an additional layer of security if used wisely. Here’s the method.
Using Screen Time Limits

Pros and Limitations of Native Locking Methods
| Method | Pros | Limitations |
| Screen Pinning | Quick, no extra setup needed | Only locks the screen, not app functionality |
| Secure Folder | Hides and locks apps effectively | Limited to Samsung devices |
| Screen Time (iPhone) | No download required, parental-level control | Not a traditional lock, easy to bypass |
| Xiaomi App Lock | Built-in, seamless integration | May vary by MIUI version |
| OnePlus App Locker | PIN and fingerprint options | May not work with cloned apps |
Why Avoid Third-Party Lockers?
Many third-party app lockers ask for unnecessary permissions, run constantly in the background, and may even affect your phone’s performance. Some are poorly maintained and incompatible with the latest Android or iOS versions. Worse, a few contain malicious code that puts your privacy at risk. Relying on your phone’s built-in tools is generally safer, faster, and more reliable.
Security Beyond the App Lock
Locking Instagram is a good start, but consider a full-stack approach:
- Turn on two-factor authentication inside Instagram settings.
- Review active login sessions regularly.
- Avoid using public or shared devices to access your account.
- Update your password every 3-6 months and don’t reuse passwords.
Voice Command Tips for Accessibility Users
If you’re someone who relies on voice commands or accessibility features, both Android and iOS offer ways to lock your phone or apps using Google Assistant or Siri Shortcuts.
For example, set up a Siri Shortcut to launch Screen Time lock, or say “Hey Google, open Instagram and lock it” if you have custom routines set.
Using Kids’ Mode or Guest Mode for Temporary Security
Another great trick is using Guest Mode (Android) or Guided Access (iPhone) if someone needs temporary access to your phone.
- Android Guest Mode: Found in the user account switcher, it lets someone use your phone without access to your data.
- iPhone Guided Access: Locks your screen to one app and disables controls.
This is especially useful when letting children use your device or handing it to someone briefly.
Final Thoughts
In 2025, smartphone makers have stepped up with built-in security that works well, especially for users who don’t want the hassle or risks of third-party solutions. Whether you’re locking Instagram out of necessity or caution, the options are now more user-friendly than ever. By combining phone-level features with smart Instagram settings, your account can remain protected with minimal effort.
