If you're worried that you might have been hacked or had any of your personal details compromised, it would be wise to change your usernames and passwords immediately. Before coming up with a string of new keys, though, you can use a service such as have i been pwned to find out if you have an account that has been compromised in a data breach.

Enter an email address or username into the search bar and it will tell you if you've been a victim.

Stay up to date

Downloading software updates as and when they're available is a good way to protect yourself. Software updates for computers, phones, tablets, and other devices generally include improved security settings and patches that fix vulnerabilities. This is also true of updates to any apps or programs that you have installed on those devices.

To make sure you receive the updates as soon as they're available you can enable automatic updates on your devices, often by looking in Settings.

Check before you download

Before downloading apps onto your phone or software on your computer do some research - check what it's asking for access to (look for apps permissions in Settings), check an app's rating in the iOS or Google Play story, read reviews online, and make sure you're downloading the official version.
