Go to your device’s app store and download a video calling app. There are many free options available, including FaceTime for iOS and Google Hangouts for Android. Make sure you know who you’re going to call before you start the process of setting up your video conferencing service.
Activate two-factor authentication on your account. This extra layer of security requires you to enter a special code sent to your phone to log in. This code changes every time you try to log in, so even if someone has your login information, they won’t be able to get into your account without the code.
Verify that the app you’re using supports encryption. You can usually see this in the app’s settings. If your chat app supports it, you should also enable “Perfect Forward Secrecy.” This ensures that any future encrypted messages aren’t compromised if someone could hack into your account and steal your encryption key.
Lastly, make sure you’re calling someone you trust and who is also using a secure video calling app. When making a video call, it’s important to know that your conversation is being kept private.
