Be careful what you share online

One of the best ways to reduce your digital footprint is to limit what you share online. There are three types of “sharing'' to consider:

Social sharing includes what you share on social media platforms like Instagram, Facebook, TikTok, and Twitter. Adding your phone number, location, or email to your social profile, or "liking" your preferred financial institutions, healthcare providers, pharmacies, etc., can give cybercriminals insight into who you are — and make it easier for them to target you.
Submissions include any online forms you might fill out. Every time you share your personal information with an organization, you expand your digital footprint — and increase the risk that your data could be misused or breached. So, think carefully before submitting an online form. If you’re prompted to fill out a form to unlock information or services, ask if there are other ways to get what you need.
Social logins may seem convenient, but are not always completely secure. For example, when you "Sign in with Google" or "Sign in with Facebook", the data you have on these sites may then be transferred to the third-party site. Always log in directly to the main account or website that you are visiting.

Delete accounts you don't need

Most people would be surprised at how many open accounts they have. When you add them all up — banking, services, newsletters, stores, etc. — the final tally is often far more than expected.

One effective way to reduce your digital footprint is to close old accounts that you no longer need.

The important thing is to not just delete or turn off these accounts but to fully close them. For example, deleting an email newsletter is not the same as unsubscribing from it or deleting your account. Similarly, turning off notifications from a shopping site isn’t the same as closing your account.

You can usually do this by going to the account’s settings page; look for privacy and security settings.

Use a Virtual Private Network (VPN), especially on public networks

Did you know that your IP address is recorded every time you visit a website?

While a hacker won’t know exactly who you are through your IP address alone, they can use it as a starting point to uncover more personal sensitive information about you.

For example, your IP address might reveal the country or city that you live in, bringing cybercriminals one step closer to tracking down your exact home address (which they can use to impersonate you and commit identity theft).

In addition, your IP address reveals a lot about your online activity — which could make it easier for hackers to target you with personalized phishing attempts or DoS (denial of service) attacks.
