How to Lock Text Messages on iPhone

Do you want to protect your private conversations on your iPhone? Then, it’s essential to know how to lock text messages securely. In this article, we will guide you through the process step by step.

Method 1: Using Screen Time

If you are using iOS 12 or later, Apple introduced a built-in feature called Screen Time that allows you to lock apps and restrict access. Follow the steps below:

  1. Open the “Settings” app on your iPhone.
  2. Scroll down and tap on “Screen Time”.
  3. Select “App Limits” and tap on “Add Limit”.
  4. Choose “Messages” from the list of apps.
  5. Set a passcode for the limit and confirm it.
  6. You can also set a time limit if desired (optional).

Congratulations! You have successfully locked your text messages using Screen Time. Now, every time you want to access your messages, you will be prompted for the passcode.

Method 2: Using Third-Party Apps

If you prefer more advanced features and additional customization options, third-party apps can be a great solution. Here are some popular options:

  • iVault – Secure Private Photos & Videos: This app not only locks your text messages but also provides secure storage for photos and videos. It offers password protection, fingerprint recognition, and even decoy modes.
  • Private Message Box – Hide SMS: With this app, you can hide your text messages behind a PIN or pattern lock.

    It also allows you to set up a fake cover, so nobody suspects you are using a message-hiding app.

  • Signal Private Messenger: Signal is an encrypted messaging app that ensures the security and privacy of your conversations. It offers end-to-end encryption and self-destructing messages for added protection.

Choose the app that best suits your needs and follow their specific instructions to lock your text messages.

Method 3: Creating a Hidden Folder

If you want a simple and discreet way to hide your text messages, creating a hidden folder can be an effective solution. Here’s how:

  1. Open the “Notes” app on your iPhone.
  2. Create a new note by tapping on the “+” button.
  3. Type any title for the note (e.g., “Recipes”, “Workout Plans”).
  4. Tap on the share icon (box with an arrow pointing up).
  5. Select “Lock Note” from the sharing options.
  6. You will be prompted to set a password or use Touch ID/Face ID for authentication.
  7. Save the locked note.

To hide your text messages, simply copy and paste them into this locked note. Now, only you can access them by entering the password or using biometric authentication (if enabled).


  • Regularly update your passcodes: To ensure maximum security, change your passcodes periodically. This practice prevents unauthorized access to your locked text messages.
  • Beware of phishing attempts: Be cautious of suspicious links or messages that ask for your passcodes.

    Legitimate apps or services will never ask for your passcodes via text messages.

  • Backup your messages: Before applying any locking methods, make sure you have a recent backup of your text messages. This precaution ensures you don’t lose any important conversations in case something goes wrong.

By following these methods, you can add an extra layer of security to your private conversations and prevent unauthorized access to your text messages on iPhone.

Remember to choose the method that best suits your needs and preferences. Stay safe and enjoy peace of mind while keeping your personal information private!
