Changing your Apple ID credit card info directly from your iPhone

Your Apple ID is used whenever you want to make purchases from one of Apple's online digital content stores. This includes the App Store, Books Store, and iTunes Store.

From time to time, you may switch credit card providers, get a new credit card number, or opt to use a different payment method than the one you're already using.

It's easy to change your Apple ID payment information right from your iPhone, iPod touch, or iPad and in this tutorial, our aim is to teach you how.

How to password protect PDF files on your Mac

Password protecting your PDF files is a great way to keep the contents from being revealed to those who you never intend to see them.

Tip: find tons of messages you didn’t know existed inside Messenger’s secret folder

What if I told you that you most likely have tons of messages you didn't even know existed, stowed away in a little-known folder on Facebook?

While messages from your Facebook friends and Messenger contacts are delivered straight to your inbox, the system filters out those it deems spam and tucks them away into a hidden vault.

Some of those filtered messages could be from a distant family member trying to re-connect with you. Others might be vitally important. If you suspect Facebook is hiding messages you should've been aware of, this tutorial will teach you how to access a treasure trove of messages that you never knew you had.

Changing your router’s DNS settings to increase speed and security

At times, you may experience slow hiccups while trying to use the internet from your home. Sometimes, these problems can be attributed to your router's DNS settings because your ISP may not always have the best DNS server speeds.

Your DNS server settings can also affect your security as you use the internet because some DNS servers come with built-in firewalls and security measures to prevent you from opening malicious or phishing websites, while others don't do anything at all to protect you.

In this tutorial, we'll show you how you can edit the DNS settings on your wireless router if you're experiencing slower internet speeds than you should be.

How to stop iPhone from tracking your location

Location Services and Privacy settings on your iPhone, iPod touch and iPad certainly provide a very detailed breakdown of the apps and system services that have requested access to your location, or are motoring your location in the background.

Options in Location Services are incredibly complex so average users may be tempted to not bother and simply leave everything on. Others may disable Location Services altogether, which isn't a very good idea either (from a usability standpoint).

Suppose you want to stop an iOS device from tracking your whereabouts, but without disrupting essential features or sacrificing much of the device's functionality.

But how precisely does one accomplish that?

There's no master switch in iOS that'd tell the device to stop monitoring your location. Plus, things get more complex if you don't know exactly which switches in Settings need flipping and which ones must be left intact.

This easy to follow step-by-step tutorial will lay out exactly the features on your device that you must disable in order to limit or prevent unwanted location tracking.

How to prevent changes to email accounts on iOS

I'm nervous every time a curious friend picks up my iPhone and ventures into Settings—not because they could see something they shouldn't, but out of fear they might mess up my multiple email accounts.

While removing email accounts from an iOS device won't wipe the server, re-adding them is a tedious process: you need to remember your access credentials and, if an account is protected with two-factor authentication, provide a verification code, too.

iOS lets you disallow changes to some device settings, including restricting all email, calendar and contact accounts so that no one can add or remove them, here's how.

How to change your Apple ID

Many of us still have the same email address associated with our Apple ID that we made years and years ago when we got our first device. We use it to sign into each and every one of our devices when we buy one new from the store or restore an existing one to factory settings.

On the other hand, times change. Sometimes you may get new email addresses, and sometimes you want to use something new to log in with rather than your high school email address. Perhaps you've made one that is a little more professional looking and seek to use it instead.

Apple provides a way to change your Apple ID email address so you can use something different to sign into everything you use. In this tutorial, we'll show you how that's done.

How to remove Adobe Flash from your Mac

The succession of vulnerabilities found in Adobe's Flash Player shows no signs of dying down: not a month goes by without Adobe releasing another yet emergency update for Flash to patch a bunch of newly discovered vulnerabilities (measuring in the dozens).

Some of them can be pretty nasty as they introduce new attack vectors for spyware, ransomware, trojans and other malicious applications that you don't want anywhere near your computer.

A few years ago, Flash Player was impossible to avoid because a bulk of web video was encoded in Adobe's proprietary Flash format, but not anymore: YouTube, Vimeo, Facebook and many other popular web services now use HTML5-based video players that work in any modern browser.

While Apple does block older, vulnerable versions of Flash in the Safari browser on macOS, you should do yourself a favor and remove Flash Player from your Mac using step-by-step instructions provided in this tutorial.
