Regaining Entry to Your Digital Costco Account

⚠️ Forgot Password

Cause: You have forgotten your password or need to create a new one.

Solution: We know being locked out is stressful. The fastest way to regain access is to click the Forgot Password? link on the sign-in page. You'll then be prompted to enter your username or email address. Costco will send an 8-digit verification code to your registered email to help you reset your password. Ensure you enter this code exactly as it appears.

⚠️ Browser Compatibility Issues

Cause: Your web browser settings are preventing the login portal from functioning correctly.

Solution: The Costco login portal requires both JavaScript and cookies to be enabled in your browser. If you're experiencing difficulties signing in, check your browser's settings to ensure these are not blocked. Refer to your browser's online help for instructions on how to enable them.

⚠️ Expired Password Reset Link

Cause: A previously sent password reset link is no longer valid because it has expired or has already been used.

Solution: If your password reset link isn't working, it might have timed out or been used already. Simply return to the sign-in page and initiate a new password reset request through the Forgot Password? link to receive a fresh, valid link.
