Cookies are turned on by default in Chrome on iPhone, but you may need to check your settings if websites say they're blocked
Chrome on iPhone stores cookies automatically unless you've changed your settings or are using private browsing mode. Most websites need cookies to remember you between visits — without them, you'll get logged out, lose items in your shopping cart, or see broken page layouts. If a website tells you cookies are off, the fix is usually just a few taps in your Chrome settings.
The steps below show you exactly where to find the cookie setting and what each option does. This takes about one minute.
Key Takeaways
- Chrome on iPhone allows cookies by default, so you only need to change this if a website specifically says cookies are blocked.
- Private browsing mode (Incognito) blocks third-party cookies automatically, even if your regular settings allow them.
- The cookie setting is in Chrome Settings under Privacy, not in your iPhone's main Settings app.
- Clearing your cache and cookies removes all stored website data, which can fix login problems but will log you out of most sites.
Turn on cookies in Chrome settings
Open Chrome on your iPhone and tap the three horizontal lines (menu icon) at the bottom right of the screen. Scroll down and tap Settings. This opens your Chrome preferences, not your iPhone settings.
Tap Privacy and security, then tap Cookies. You'll see three options: "Block all cookies", "Block third-party cookies in Incognito", and "Allow all cookies". The third option is the default and allows all cookies. If it's not already selected, tap it now. Close the menu and return to the website — it should now accept cookies.
If you see "Block all cookies" selected, that's why websites are telling you cookies are off. Tap "Allow all cookies" to fix it. You may need to refresh the website or close and reopen it for the change to take effect.
Check if you're using private browsing mode
Private browsing (called Incognito in Chrome) blocks third-party cookies even when your main settings allow them. Look at the bottom of your Chrome screen — if you see a number in a circle (like "1" or "3"), you're in Incognito mode. That number shows how many Incognito tabs you have open.
To switch back to regular browsing, tap the menu icon (three lines) at the bottom right, then tap the number showing your Incognito tabs. Tap Exit to close all Incognito tabs and return to normal Chrome. Open the website again in a regular tab, and cookies should now work.
Clear your cache and cookies if websites still don't work
Sometimes old or corrupted cookie data prevents a website from working correctly. Clearing your cache and cookies removes all stored website data and forces Chrome to start fresh. This will log you out of most sites, but it often fixes login problems or broken page layouts.
Open Chrome, tap the menu icon (three lines) at the bottom right, and tap Settings. Tap Privacy and security, then tap Clear browsing data. Make sure Cookies and site data is checked, then tap Clear browsing data at the bottom. Wait a few seconds for the process to finish, then close the menu.
Go back to the website and try logging in again. It should now accept your cookies normally. You may need to log in to other sites you use regularly, since clearing cookies removes all stored login information.
Understand what cookies do and why websites need them
Cookies are small files that websites store on your phone to remember information about you. They let websites keep you logged in, remember items in your shopping cart, save your preferences (like dark mode or language), and track which pages you've visited.
There are two main types: first-party cookies (set by the website you're visiting) and third-party cookies (set by advertisers or analytics companies). Chrome blocks third-party cookies in Incognito mode by default to protect your privacy, but allows them in regular browsing. Most websites need at least first-party cookies to work properly.
What to do if a website still won't accept cookies
If you've turned on cookies in Chrome settings and you're not in Incognito mode, but a website still says cookies are blocked, the problem may be on the website's end, not your phone. Try these steps: refresh the page by pulling down from the top of the screen, close and reopen Chrome completely, or try the website in a different browser like Safari.
If the website works in Safari but not Chrome, the issue is specific to Chrome on your phone. Try clearing Chrome's cache and cookies again (see the section above), or contact the website's support team to report the problem. If the website works in Chrome on a computer but not on your iPhone, it may not be designed to work properly on mobile devices.
Frequently Asked Questions
Will turning on cookies make my phone less secure?
Cookies themselves don't make your phone less secure. They're just small text files that store information like login sessions. The real security risk comes from malicious websites or apps, not from cookies. Chrome's privacy settings protect you by blocking third-party cookies in Incognito mode and warning you about unsafe websites.
What's the difference between clearing cookies and blocking cookies?
Blocking cookies prevents websites from storing new cookie files on your phone. Clearing cookies deletes all the cookie files you already have stored. If you block cookies, websites won't remember you. If you clear cookies, you'll be logged out of sites, but new cookies can still be stored once you log back in.
Do I need to turn on cookies for every website?
No. The cookie setting in Chrome applies to all websites at once. Once you turn on "Allow all cookies" in Chrome settings, every website can store cookies on your phone unless you change the setting again. You don't need to adjust cookies for individual sites.
Why does a website say cookies are required if I already have them turned on?
The website may be checking for a specific cookie it tried to set earlier. If that cookie wasn't stored (because you were in Incognito mode, or the website had a problem), the site will ask you to turn on cookies. Try refreshing the page or closing and reopening Chrome, which usually fixes this.
