To enable cookies on your iPhone in Safari, open Settings > Apps > Safari > Advanced and turn off Block All Cookies. Return to the website and try signing in again before changing any other privacy settings.
The short version
- In Safari, turn off Block All Cookies first.
- A website's cookie prompt is separate from your browser settings.
- Check extensions before allowing cross-site tracking.
- Chrome keeps cookies enabled automatically on iPhone.
- In Firefox or Brave, try changing protection for the affected website first.
- Clearing cookies removes saved website login data, so leave that for later.

Allow cookies in Safari
Open Settings, tap Apps, then choose Safari. Open Advanced and turn off Block All Cookies. On iOS 17, start at Settings > Safari instead of looking under Apps.
Blocking cookies can prevent website sign-ins. After changing the switch, return to the affected site and try the action that failed. If a cookie prompt appears, choose the site's cookie options based on what you want to allow; enabling browser cookies does not choose the site's consent options for you.
Make sure you are checking the browser that actually opens the website. If you want links to open in a particular browser, change your default web browser on iPhone, then follow the matching section below.
Pause a Safari extension
A content blocker can block cookies and other website resources. When one site fails, open it in Safari and tap the Page Menu button on the left side of the search field. Tap Manage Extensions and turn the relevant extension off for that website.
For a broader check, open Settings > Apps > Safari > Extensions, then tap the extension and turn off Allow Extension. On iOS 17, use Settings > Safari > Extensions. Try the website again, and restore the extension if pausing it makes no difference.
Check cross site tracking in Safari
Safari limits third-party cookies and data by default with Prevent Cross-Site Tracking. That setting is separate from Block All Cookies, so allowing ordinary website cookies does not require switching both protections off. Leave tracking prevention on unless you need to check a feature that depends on another website.
To check it, open Settings > Apps > Safari and turn off Prevent Cross-Site Tracking. On iOS 17, use Settings > Safari. Try the affected feature again, then turn the setting back on if it does not help; leaving it off allows cross-site tracking.
Clear Safari website data if the problem continues
Before deleting stored data, use a regular browsing tab for your next check. If you are in a private session, turn off private browsing on iPhone and return to the website. Keep your checks in the same browsing mode so you can compare the result after each change.
If the earlier checks did not help, open Settings > Apps > Safari > Advanced > Website Data. Tap Remove All Website Data, then Remove Now. This clears cookies and cache while keeping your browsing history, but it also removes data websites use to save login information.
Have your sign-in details ready before clearing anything, then revisit the website. Clearing data is a reset of stored information, so keep Block All Cookies off as well.
Fix Chrome cookie problems on iPhone
Cookies are automatically enabled and stay enabled in Chrome on iPhone. You do not need to find an enable switch in Chrome. If a Google sign-in error appears in Safari instead, use the Safari steps above.
To clear Chrome's stored cookies, tap More, then Delete Browsing Data. Choose a Time Range covering the affected visits, then tap Browsing Data. Select Cookies, Site Data, deselect the other data types you want to keep, tap Confirm, then tap Delete Browsing Data.
If your app shows the Settings route, tap More > Settings > Privacy and Security > Delete Browsing Data. Select Cookies, Site Data and uncheck the other items, tap Delete Browsing Data twice to confirm, then tap Done. Use Chrome's browsing data controls if you need help choosing what to remove.
Deleting cookies can sign you out and remove website preferences. Try signing in again after the removal finishes, and avoid deleting unrelated data just to troubleshoot cookies.
Change Firefox tracking protection
In Firefox, open the affected website and tap the shield icon next to the URL bar. Turn off Enhanced Tracking Protection for that site, then try the page again. Use this site exception first so you can check the problem without changing protection everywhere.
In Strict mode, you can also long-press the refresh button and tap Reload without Tracking Protection for a temporary check in the current tab. For a broader change, tap Firefox's menu button, open Settings > Tracking Protection, and switch off Enhanced Tracking Protection. These Firefox controls do not change Apple's Intelligent Tracking Prevention, which is controlled through device settings.
Adjust Brave Shields and privacy
Open the affected page in Brave and tap the Brave Shields icon. Temporarily turn Shields off for that website, then try the page again. Restore protection if that change does not resolve the problem.
To review the wider defaults, open Menu > All Settings > Shields & Privacy. You can also reach them through the Shields icon and Change Shields Global Defaults. Check each protection's description before changing several at once, and remember that global changes do not override existing settings for individual sites.
Check work or school restrictions
If a Safari cookie setting cannot be changed, check Settings > General > VPN & Device Management for an installed profile. An organization can manage Safari's cookie settings and prevent you from changing them. The profile check takes only a moment; changing an organization policy requires help from its administrator.
Contact your work or school IT team and ask whether its Safari cookie policy is blocking the website. Ask them to review both cookie blocking and cross-site tracking restrictions. Avoid deleting the profile as a troubleshooting shortcut, because removing it also deletes its associated settings, apps and data.
Frequently Asked Questions
Should Block All Cookies be on or off on iPhone?
Turn Block All Cookies off to let Safari websites use cookies. Start with that switch and try the website again before changing tracking protection.
Does Chrome on iPhone have a cookie setting?
Chrome automatically enables cookies and keeps them enabled on iPhone. Its browsing data controls let you delete stored cookies if you need to reset a site's data.
Why does one website still say cookies are disabled?
A content blocker, tracking protection or organization policy may still interfere with the page. Check those controls one at a time, and review any cookie prompt the website displays.
Is the old Settings > Safari cookie menu still current?
Current software places Safari under Settings > Apps, with Block All Cookies inside Advanced. On iOS 17, Safari is directly under Settings, so the older starting point remains relevant.
Do I have to allow cross site tracking to enable cookies?
Start by turning off Block All Cookies and leave Prevent Cross-Site Tracking on. The latter controls Safari's limits on third-party cookies and data, so change it only when checking a specific problem.
Will clearing cookies sign me out?
Clearing cookies removes data websites use to remember sign-ins, so be ready to sign in again. It does not enable cookies by itself; check the browser's blocking controls separately.
