While trying to access some websites, users have reported seeing this error message: This server could not verify that you are authorized to access the document requested. Either you supplied the wrong credentials (e.g., bad password), or your browser doesn’t understand how to supply the credentials required.

Seeing this error message means that you can’t use your favorite browser software to access the information on the website/websites you subscribed to by using the fast log-in method with either a Gmail, or Facebook account.

In this article, we will explore a way to try and fix this error message, so you can log into your preferred services without any issues. Read on to find out how.

What to do if my browser doesn’t understand how to supply the credentials required?

1. Try a different browser

To eliminate this problem, try logging in with a different browser.

Install Opera

Opera is a fast and secure browser, and unlike other solutions, it doesn’t collect any personal information about you.

In fact, Opera’s main focus is user privacy and security that is achieved thanks to the built-in VPN.

Plus, you get way more than a simple browser by deciding to use Opera. With just one single app, you can eliminate the clutter and stress of running third-party software for each and every one of your digital needs.

Opera covers pretty much all of them from safe, anonymous browsing and unblocking geo-restricted content thought its in-built VPN tool, to taking snapshots without ever leaving the browser.

Its most powerful features focus on the user and were designed specifically with the end user’s browsing experience in mind. That is why features like the adblocker or the integrated workflows and floating video windows were injected into Opera during its latest transformation.

Let’s quickly look at its key features:

  • It also comes with support for VR Players, standard security protocols
  • Instant search and integrated ad-blocker
  • New readers, battery saver mode, currency unit, and time zone converters, etc.
  • Countless customization options for a friendlier than ever UI
  • Speed tab to further accelerate your workflows and more
