Enable Cookies in Safari on iPhone
This guide will step you through the process of configuring Cookies in Safari on iOS - this process is the same for iPhone, iPad and iPod even though the screenshots might look slightly different.
Open the "Settings" App
Return to the Home Screen by pressing the round button underneath the screen. You will see the grid of icons. Then, find the "Settings" icon and tap on it.
Scroll and tap on the "Safari" item
The Settings screen is longer than the actual screen of the iPhone or iPad, so to reach the "Safari" section you will need to scroll the screen down a bit by dragging on the screen with your finger.
When you see the Safari item, tap on it to see the options for Safari.
Scroll down and tap on "Block Cookies"
Block Cookies is located in the Privacy & Security section. You'll need to scroll down to be able to see it. When you see it, tap on it.
Choose your preferred Cookies setting
You are now presented with four options for your Cookies preference.
"Always Block" and "Always Allow" are pretty straight forward - you can either universally allow or block sites from putting cookies on your iPhone.
The other two options are a little more complex. In a sense, they both relate to allowing or blocking "third-party cookies", although the distinction between the two given choices is fairly subtle.
Referring to Apple's Help Documentation on the matter indicates that the "Allow from Current Website Only" choice means strictly that only the website you are viewing is allowed to set cookies on your iPhone.
"Allow from Websites I visit". Ok this one's complicated: Say there's a website that you normally visit, but you're not on that website right now, you're on another website, but that website has embedded content from the first website. With this setting, that content will be allowed to set and read cookies on your computer.
In other words, say you normally visit YouTube, but you're not on YouTube right now, you're reading someone's blog. And they've embedded a YouTube video in one of their posts. With this setting, because you normally visit YouTube (even though you're not on it right now) YouTube is permitted to create and read (only their own) cookies at that point.
This is the default setting and is slightly more permissive than the other "Allow from Current Website Only" setting.
You need to pick which option you want to enable. The default "Allow from Current Website Only" is probably fine for most needs. If you're a little more cautious but still want most websites to work, you might select "Allow from Current Website Only".
