Fix sign-in problems on Yahoo
Many sign-in and account problems are due to how your browser handles cookies (small pieces of information stored by your browser to help identify you). Here’s how to make sure your browser handles them correctly.
Fixing sign-in problems
- Your computer's date may be wrong: Cookies rely on your computer's clock, and an incorrect date can confuse your browser, causing it to not recognize your cookie. To fix this, set the correct time and date on your computer.
- A security program or firewall on your computer may be blocking cookies: Anti-virus, anti-spyware, and firewall programs on your computer can block cookies being sent to your computer. Try temporarily disabling the security program before signing in. For more information, see how to temporarily turn off anti-virus, anti-spyware, and firewall products.
- Your network may have a firewall that doesn't allow you to receive cookies. If you are connecting from a business intranet, check with your system administrator.
- Your Web browser may not be set to accept cookies: Most browsers have several options for accepting cookies. Learn more about setting your browser to accept cookies.
