Cookies are on by default in Chrome on iPhone, but you can check your settings if websites aren't working right
Chrome for iPhone has cookies turned on automatically when you install it. You don't need to do anything to enable them. However, if a website isn't loading properly, won't let you stay logged in, or keeps asking you to sign in repeatedly, your cookie settings may have been changed — either by you, by an update, or by a privacy setting you turned on.
The steps below show you how to check whether cookies are on and turn them back on if they're off. This takes about one minute.
Key Takeaways
- Cookies are enabled in Chrome on iPhone by default, so most people don't need to change anything.
- If websites aren't remembering you or keeping you logged in, your cookie settings may have been turned off.
- You can check and change cookie settings in Chrome's Privacy menu, which is inside Settings.
- Turning cookies back on usually fixes login problems and makes websites remember your preferences.
How to check your cookie settings in Chrome on iPhone
Open Chrome on your iPhone. Tap the three horizontal lines (called the menu button) at the bottom right of the screen. Scroll down and tap Settings.
Tap Privacy and security. You will see a list of options. Look for Block all cookies — if this toggle is turned on (it will be blue or green), cookies are blocked. If the toggle is off (it will be gray), cookies are allowed.
If you see Block all cookies turned on, tap it once to turn it off. Chrome will return to allowing cookies. Close Settings by tapping the back arrow or swiping back, then refresh the website that wasn't working.
When cookies should stay on
Leave cookies turned on for normal browsing. Cookies let websites remember things like your login information, items in your shopping cart, and your language preference. Without them, you would have to sign in to every website every single time you visit.
Some people turn off cookies because they think it protects their privacy, but this is only partly true. Blocking all cookies makes websites harder to use and doesn't stop websites from tracking you — they just use other methods. If privacy is your concern, using Chrome's Incognito mode (which doesn't save cookies or browsing history) is more effective than blocking cookies entirely.
What to do if turning cookies on doesn't fix the problem
If websites still aren't working after you turn cookies on, try clearing your browser cache. This removes old, possibly corrupted cookie files and forces Chrome to download fresh ones.
Go back to Settings > Privacy and security. Tap Clear browsing data. Make sure Cookies and site data is checked (it usually is by default). Tap Clear browsing data again to confirm. Then go back to the website and try logging in again.
If the problem continues, the issue is likely with the website itself, not your Chrome settings. Try the same website in Safari (Apple's built-in browser) to see if it works there. If it does, the website may have a bug with Chrome on iPhone.
The difference between cookies and tracking
Cookies and tracking are related but not the same thing. A cookie is a small file that a website stores on your phone. Tracking is when a company follows what you do across multiple websites.
Chrome has a built-in tracker blocker called Privacy Sandbox that limits cross-site tracking even when cookies are on. You don't need to turn off cookies to reduce tracking — Chrome is already doing some of that work for you. If you want more control, you can use Incognito mode for sensitive browsing, or you can use a privacy-focused browser like Firefox Focus, which blocks trackers by default.
Why websites ask you to accept cookies
When you visit a website and see a banner asking you to accept cookies, that's usually because the website is required by law (in Europe and some other places) to tell you what it's doing. The banner doesn't mean cookies are off — it means the website is asking your permission to use them.
You can usually click Accept or Reject. If you reject, the website will still work, but it may not remember you or show you personalized content. Accepting is usually the simpler choice unless you're on a public device or don't want that website to remember you.
Frequently Asked Questions
Do I need to restart Chrome after turning cookies back on?
No. Chrome applies the change immediately. You can refresh the website you were trying to use right away and it should work. If it doesn't, wait a few seconds and try again, or close and reopen the website.
Will turning on cookies slow down my iPhone?
No. Cookies are tiny files — usually just a few kilobytes each. Even with thousands of cookies stored, they use almost no space and have no noticeable effect on speed or battery life.
Can I turn cookies on for some websites and off for others?
Chrome on iPhone doesn't have a per-website cookie setting. You can only turn all cookies on or all cookies off. If you need more control, you can use Incognito mode for websites you don't want to remember you, while keeping cookies on in regular browsing.
What if I turned on "Block all cookies" and now I can't remember why?
Most people turn it on by accident or because they read something about privacy online. Unless you have a specific reason to block cookies — like using a shared device — turning it back on is safe and will make websites work better.
