Last updated: May 6, 2017 - 10:34am EDT

Thinking about using iMessage on your Apple device to communicate with your family and friends, but want to know more about how safe and secure it is before getting started? If so, this article is for you. This article will explain how secure the app is, and cover some information about message encryption. We’ll also be giving you a few useful tips to help you stay safe when using this app.

Is iMessage secure?

iMessage is one of the most secure messaging apps available right now. Messages sent through the app are encrypted for added security. When you send a message to someone, the only people that will be able to read it are those included in the conversation. Your messages will be private and secure.

Are iMessage messages encrypted?

Messages sent through iMessage are protected by end-to-end encryption. This means that if someone were to try to hack into your conversation while messages are in transit, they wouldn’t be able to decipher the message content. This is done to add to the privacy, security, and safety of the user.

End-to-end encryption essentially obscures information when it is being sent from one device to another. This ensures that the only person who will be able to receive your message is the intended recipient.

4 iMessage safety tips

1. Only use iMessage to speak to people you already know and trust.

If someone sends you a message, and you don’t already know them, don’t reply to it. Only send messages to phone numbers and email addresses of people you know. Be especially wary of anyone asking for your personal or financial information. To put it simply – don’t talk to strangers.

2. Keep in mind that your messages can be shared by people you send them to.

Remember that once you send something to someone though iMessage, they have the ability to show or share that message, picture, video, etc. to other people. Going along with our first tip, make sure you trust the person/people you’re messaging not to share the details of your conversation with others.

3. Block anyone who is bothering or harassing you.

If someone happens to be bothering you through the app, you can block them so you won’t receive their messages anymore. If the situation escalates and becomes serious or extreme, contact your local authorities to report it.

4. Try to stay off of unsecure Internet networks.

This tip is more general, but if you want to be extra careful about your privacy, don’t connect your device to public or unsecured Wi-Fi networks. Public Internet networks generally aren’t password protected, meaning anybody can use them. Since you can’t guarantee that everyone using a public Wi-Fi network is trustworthy, you shouldn’t risk connecting to them. Someone could potentially try to steal your personal information.

5. Restrict access if you don’t want your children using it.

These days, it is quite common for parents to purchase devices like iPads for their children.Although you might be okay with your child being able to use some apps on the device, you may want to restrict access to others. If you don’t want your child to be able to use iMessage, first disable the service.

Disable iMessage settings

You can prevent them from enabling the service by going to Settings > General > Restrictions > Accounts. Then, tap Don’t Allow Changes.
