To securely store or transfer files, you can zip them with a password, I’ll share the how-tos and some tricks I’ve picked up along the way. So, let’s see how you can password protect a zip file on Mac.

Before We Begin:

While password-protecting a zip file is a good first step, it’s important to consider the overall security of your computer system. Thankfully, software solutions like MacKeeper can help protect your Mac from various online threats. MacKeeper’s ID Theft Guard feature, for instance, provides robust protection against identity theft and cybercrime. This feature monitors your sensitive data 24/7 for any signs of unauthorized access or suspicious activity.

Overcome Password Protection Limitations With MacKeeper

While password protection is an effective way to secure your files, remember it could be more foolproof. Hackers can use brute force attacks to guess your password or exploit vulnerabilities in your software. Using other security measures besides password protection is vital to maximizing your security.

MacKeeper can ensure the highest level of protection for your data in just a few simple steps. Here’s how:
