Imagine this: you are trying to access an online account or website only to get the 401 unauthorised error. Frustrating right? This error is not just a random roadblock—it’s your device’s way of saying, “You don’t have permission to enter”, due to an authentication problem, indicating that it doesn’t recognise you.
The good news is you can fix it easily if you know the reason behind the error and how to fix it.
In this guide, we will explore the common causes of 401 unauthorised errors, learn practical solutions and sharp, effective tips to prevent it from happening again.
What Does a 401 Unauthorised Error Mean
A 401 error is a website or app response saying, “You are not allowed inside the webpage!” Please give us your incorrect credentials. Yours are either invalid or missing.” It is an error that does not completely deny you access, but it suggests that entering valid login details may allow you entry.
The 401 error does not occur for simple web login. For example, if you are trying to login into any application (like Facebook, Gmail, etc.), and you enter wrong credentials, you will be notified that the respected Username or Password is incorrect.
However, for stricter web pages where sensitive or critical data is stored, such as APIs or admin panels, entering the wrong credentials may redirect you to a 401 error rather than alerting you that the credentials are incorrect.
Common Causes of a 401 Error
Several factors can trigger a 401 Unauthorised Error. Here are the most common causes:
- Wrong Login Details: A simple typo in your username or password can trigger this error. Even small mistakes like incorrect capitalisation or outdated passwords can lead to access denial.
- Expired Tokens: Many websites use tokens to remember logged-in users. These tokens have expiration times, and when they expire, the system may no longer recognise your session.
- Insufficient Permissions: Even with valid credentials, your account might lack the necessary permissions to access specific pages or features. For example, accessing admin-only pages with a standard user account will trigger this error.
- Server Configuration Issues: Sometimes, the error happens due to the site owner’s misconfiguration of the server settings, which does not allow the authentication request to be properly accepted.
- Browser Cache and Cookies: Your browser’s cache and cookies sometimes become corrupted and interfere with proper authentication. This is where a website assumes you are using another account and rejects your login attempt.
How to Fix a 401 Unauthorised Error
Fixing a 401 Unauthorised Error is straightforward. To regain access, follow the steps below:
Step 1: Verify Login Details
Make sure that your username and password are correct. Use the option “Forgot Password” if you are unsure about it.
Step 2: Log Out and Log Back In
Sometimes, simply logging out and back into the app can refresh your session and resolve the error. This step is to reauthenticate your system.
Step 3: Clear Browser Cache and Cookies
Removing old, cached data and cookies can eliminate conflicts causing the error. This step is especially useful if the issue persists after verifying your login details.

Step 4: Try a Different Browser or Device
Switch to another browser or device to identify if the issue lies with your current setup. Some browsers may handle authentication differently, and a fresh environment can resolve hidden conflicts.
Step 5: Check Account Permissions
Ensure your account is allowed to go to the page or see the content you want. If you’re trying to get into places that are off-limits, you might have to make your account better or ask the website’s help team.
Step 6: Contact Support
Get in touch with the help team. If nothing else works, ask the website’s help team to give you a hand. Give them information about the problem, like when it happens and what you do before it happens, so they can fix it faster.

How to Prevent Future 401 Errors
Preventing 401 Unauthorised Errors is just as important as fixing them. Here are some proactive measures to ensure a smoother online experience:
1. Enable Two-Factor Authentication (2FA)
Turn on the second safety check or 2FA. It increases safety because it asks for one more proof step. This makes sure only the right people can get in. It lowers the chances of unwanted logins.
2. Secure Login Credentials
Keep your login details safe. Make sure every account has a different, hard-to-guess password. Store all these passwords in a secure way with a password manager.
3. Regularly Clear Cache and Cookies
Clearing your browser’s memory periodically prevents old or corrupted data from causing conflicts. Set a monthly schedule to clear cache and cookies for optimal performance.
4. Save Login Details on Trusted Devices
Save your credentials securely on trusted devices to avoid frequent manual logins. However, ensure these devices are protected with strong passwords or biometric authentication.
5. Update Your Browser
Keeping your browser updated ensures compatibility with the latest website technologies. Updates often include fixes for security vulnerabilities and improved performance.
6. Check Permissions for Restricted Areas
Before accessing sensitive areas like admin panels or APIs, confirm that your account has the required permissions. This step avoids unnecessary access issues.
