How to Fix Error Code ERR_MISSING_AUTH_CREDENTIALS

  1. Reload the Page and Re-Enter Credentials

  2. Clear Chrome's Saved Passwords and Auth Credentials

    Clearing saved passwords will remove stored login info for all sites. Make sure you know your passwords before doing this, or export them first via Chrome's Password Manager export feature.

  3. Disable or Reconfigure Proxy Settings

    Do not disable proxy settings on a managed corporate or school device without permission from your IT department.

  4. Flush DNS Cache and Reset Network Settings

  5. Check and Disable Chrome Extensions

  6. Reset Chrome's Flags and Authentication Settings

  7. Reset Chrome to Default Settings

    This step resets your Chrome customizations. Back up any important settings or extension configurations before proceeding.

  8. Update or Reinstall Google Chrome

    Before uninstalling, sign in to your Google account so your bookmarks and settings sync and can be restored after reinstallation.

When to Call a Professional

If you are on a corporate or institutional network and the error persists after following all steps, contact your IT department — the problem may involve server-side Kerberos or NTLM authentication configuration that requires admin-level network changes. Similarly, if the website itself is returning the authentication error for all users, the issue is on the server side and must be resolved by the site's web administrator, not end users.

Frequently Asked Questions

What causes ERR_MISSING_AUTH_CREDENTIALS in Chrome?
This error is caused when Chrome cannot find or supply the HTTP authentication credentials required by a website or proxy server. Common triggers include missing or expired saved passwords, a misconfigured proxy, corrupted Chrome profile data, interfering browser extensions, or outdated Chrome settings that do not match the server's authentication requirements.
Why does ERR_MISSING_AUTH_CREDENTIALS only happen on one specific website?
If the error only appears on one site, it usually means Chrome has stored incorrect or outdated credentials specifically for that site, or that site's authentication configuration has changed. Try clearing the saved password for that site in Chrome's Password Manager and removing its HSTS policy via chrome://net-internals/#hsts, then reload and re-enter your credentials.
Does ERR_MISSING_AUTH_CREDENTIALS mean my account is hacked or compromised?
No — this error is a browser-side authentication configuration issue, not a sign of a hack or compromise. It simply means Chrome could not locate or submit the required login credentials to the server. It does not indicate any unauthorized access to your accounts.
Can a VPN cause the ERR_MISSING_AUTH_CREDENTIALS error?
Yes. VPN extensions or apps can intercept or modify HTTP authentication requests, causing Chrome to fail to deliver credentials correctly. Try disabling your VPN temporarily and reloading the page. If the error disappears, the VPN or its Chrome extension is the likely cause. Check the VPN's settings or contact its support team for a fix.
Will clearing browsing data fix ERR_MISSING_AUTH_CREDENTIALS?
Clearing browsing data — especially cached files and saved passwords — can fix this error if it is caused by corrupted or outdated stored credentials. Go to Chrome Settings > Privacy and security > Clear browsing data, select 'All time', check 'Passwords and other sign-in data' and 'Cached images and files', and click 'Clear data'. After clearing, reload the site and re-enter your credentials when prompted.
