Nowadays, protecting your electronic devices with the right apps is just as important as securing your home with sturdy locks. After all, whether it’s your PC, laptop, smartphone, or even your Nintendo Switch, any one of them has access to sensitive information and accounts that people with malicious intent would love to get their hands on.

With internet banking and shopping rapidly becoming the norm, especially during the current pandemic, your devices are likely filled with credit/debit card and financial account information along with tons of your personal details, which makes being hacked far more dangerous than losing your wallet in this day and age.
