With the increasing vulnerabilities to cybercrime and identity theft, safeguarding personal information has become more critical than ever. Apple, as one of the world’s leading technology companies, understands the need for user privacy, and they have equipped their devices with several security features, such as the option to lock messages on iPhone.

When you lock messages on your iPhone, your information and data are protected from would-be snoops or potential hackers. Even if someone gains access to your phone, they cannot read your private messages without unlocking it. This security feature gives you peace of mind that your sensitive information remains confidential and secure from unauthorized people.

Moreover, locking messages on iPhone is important because it may contain sensitive information such as account details, bank PINs, social security numbers, and other personal data. Keeping this type of information protected is critical to prevent any identity theft, and the possibility of losing personal and financial assets.

As messaging on mobile devices has become a primary method of communication, locking messages on iPhone is essential to ensuring the safety and privacy of personal information. In just a few quick steps, you can protect your sensitive information with your device’s passcode, which gives only authorized users access to your messages. While it may seem like a small step, locking your messages on iPhone can potentially save you from numerous complications and headaches that might come with cybercrime and identity theft.

Step-by-Step Guide to Lock Messages on iPhone

Privacy is a crucial aspect of our digital lives. We tend to store sensitive information such as personal messages, bank account details, and passwords on our smartphones. This is where the need to lock messages on iPhone comes in. In this article, we’ll guide you through the process of locking messages on your iPhone to keep your sensitive conversations protected.

Step 1: Open Settings

Firstly, go to your iPhone’s home screen and tap on the Settings app icon. It’s the grey icon with gears on it. Once you enter the Settings app, scroll down until you find the “Screen Time” option.

Step 2: Select App Limits

After tapping on “Screen Time,” you’ll find various options on the next screen. Look for “App Limits” and click on it. This option lets you limit the access of certain apps on your iPhone.

Step 3: Choose Messages

Next, you’ll see a blue “Add Limit” button. Click on it, and you will find a list of apps that are commonly used on your iPhone. Locate “Messages” in the list and select it. Now, click on “Next” in the top-right corner to proceed to the next step.

Step 4: Set a Passcode

After selecting “Messages,” you are given the option to set limits on how much time you want to spend on the app in a day. You can choose to uncheck “Block at End of Limit” if you don’t want those messages to be blocked once the limit runs out. Next, you are asked to set up a passcode.

For iPhone models with Face ID, you may need to enter your device’s passcode to proceed. After that, you should create a four-digit passcode to protect your message app’s content.

Step 5: Enable “Share Across Devices.”

The final step involves enabling a feature on your iPhone called “Share Across Devices”. To do this, go back to the Screen Time settings menu and toggle the switch next to “Share Across Devices” to the ON position. This allows you to sync your password with your other Apple devices.

That’s it! You’re done securing your messages on your iPhone. Now, every time you try to access the messages app, you’ll need to enter your passcode to unlock it.


Locking messages on your iPhone is a quick and easy way to increase your privacy and security. It protects you from unauthorized access to your sensitive information by ensuring that only you can access your messages. Remember to update your passcode every 6 months, and don’t share it with anyone else. By taking these simple steps, you can breathe easier when it comes to the safety of your messages on your iPhone.

Using Third-Party Apps for Message Locking on iPhone

Apple’s iOS operating system has stringent security measures to protect user data. However, some iPhone users prefer to add an extra layer of protection to their message conversations. One way to lock messages on an iPhone is by using third-party apps. Some popular apps for message locking are:

1. Signal

Signal is an encrypted messaging app that offers end-to-end encryption for messages, calls, and video chats. It also supports disappearing messages that self-destruct after a set time. Signal’s security features, combined with its user-friendly interface, have made it a popular choice among privacy-conscious iPhone users. To lock messages on Signal, you can set a passcode or use Touch ID/Face ID to unlock the app.

2. WhatsApp

WhatsApp is a messaging app that offers end-to-end encryption for messages, voice notes, and calls. It also supports disappearing messages that erase after a set time. With over 2 billion users worldwide, WhatsApp is one of the most popular messaging apps. To lock messages on WhatsApp, you can set a passcode or use Touch ID/Face ID to unlock the app or individual chats.

3. Telegram

Telegram is another messaging app that offers end-to-end encryption, self-destructing messages, and secret chats. Telegram’s secret chats have an additional layer of encryption and are not stored on Telegram’s servers. Telegram also allows you to password-protect the app and individual chats. Additionally, Telegram users can set a lock timer to automatically lock the app after a set period of time.

These apps offer various ways to lock messages on an iPhone. However, it is essential to note that using third-party apps for message locking comes with its own set of risks and considerations. Installing third-party apps can leave your device vulnerable to security breaches and malware attacks. Therefore, it is crucial to download apps from trusted sources and regularly update them to the latest version. Additionally, it is recommended to disable notifications from these apps to prevent private messages from appearing on the lock screen.

In summary, using third-party apps for message locking on an iPhone is a viable option for those looking to add an extra layer of protection to their message conversations. However, it is important to be mindful of the risks and take necessary precautions to protect your data and privacy.

Best Practices for Message Privacy on iPhone

iPhone is one of the most popular and secure smartphones on the market, but it’s still important to take steps to protect your privacy when using messaging applications. Fortunately, there are a few simple best practices you can follow to keep your messages and personal information safe. Here are some tips to help you lock messages on your iPhone:

1. Update your iOS and apps

Apple releases updates to iOS and various apps frequently, which often include important security fixes that address vulnerabilities that cybercriminals can use to gain access to your messages and other sensitive data. Therefore, make sure to always update your operating system and apps to stay protected against the latest security threats.

Criminals often use links and attachments in messages as a way to trick you into downloading malware or giving away personal information. If you receive a message from someone you don’t know or that seems suspicious, don’t open any links or attachments that it contains. Instead, delete the message immediately. If you receive a message from someone you do know but that contains suspicious links or attachments, contact the sender to confirm that it’s safe before opening.

3. Use two-factor authentication

Two-factor authentication (2FA) adds an additional layer of security by requiring a second form of authentication in addition to your password, such as a fingerprint or a verification code sent to your phone. Many messaging apps, like iMessage and WhatsApp, offer 2FA as an option. Enabling it can help prevent unauthorized access to your messages in case someone gets hold of your password.

4. Regularly change your passcode

Your iPhone passcode is the key to your device and all of the personal information it contains, including your messages. Therefore, it’s important to regularly change your passcode to prevent unauthorized access to your device. To change your passcode, go to Settings > Face ID & Passcode (or Touch ID & Passcode if you have an older iPhone) and follow the on-screen instructions.

By following these best practices for message privacy, you can help keep your messages and personal information safe from cybercriminals and other malicious actors. Remember to always stay vigilant, and if you suspect that your iPhone or messaging apps have been compromised in any way, don’t hesitate to seek professional help from a trusted cybersecurity provider.
