Blink Camera Authentication Failed: How To Fix

When it comes to Smart Home Security Cameras, none of them are perfect. The same goes with Blink Cameras, authentication errors being one of them.

I personally use Blink cameras around my house. They are easy to use, have plenty of features and most importantly provide all of the above at an affordable price. 

This is why when my Blink app started showing the authentication failed message out of the blue, I had to find a solution to it.

If you keep seeing authentication failed messages while trying to log in or access the Blink cameras, check your network connection for any issues and power cycle your router. If you are connected to a VPN, disable it. Ensure that you use the correct login credentials.

Let's now dive right into the many causes and fixes for authentication failed messages on Blink:

Check the Network Connection


The authentication failed issue is most probably caused due to a weak network connection.

The message can pop up when the Blink camera fails to communicate properly with its servers, much like the Blink Command failed to complete issue.

A strong and proper internet connection is required for both your Blink camera to work correctly. Make sure you have an upload speed of at least 2 Mbps to ensure smooth operation. 

Ensure that your cameras are in direct line of sight to your router. Thick walls might cause network hindrance and cause a drop in network speed. 

If your camera is installed in places such as the attic or the basement, it is easier for it to lose connection. Try moving the camera closer to the router or consider buying a signal booster.

Having multiple devices connected to wifi will also cause a drop in internet speed. Disconnect some of the devices as sometimes there is a limit to the device connected to your wifi at a time. 

You could also switch to 2.4 GHz wifi if you are using 5 GHz at the moment.

Even though 5 GHz offers greater speed, 2.4 GHz wifi is more reliable and offers greater signal strength. You can change this in the wifi router settings.

You can check your internet speed within the Blink camera app itself, to check the network speed within the app:

1. Navigate to the Blink app on your mobile device

2. In the app, navigate to Device settings

3. Click on General settings 

Blink General Settings

4. Here you will be able to see a Camera to wifi option which will show you the network speed of the connection

Blink Connection status

The speed will be indicated by numerical values or bars. Check and see if the network speed is adequate.

You can also see the signal strength of the Sync Module from the same tab. Ensure the signal is adequate so as to not trigger the Sync module to go offline.

You can also check your network speed using third-party sites like Ookla. Download the app or access it from a browser to get a real-time account of the various networking parameters.

If the network speed is low, try repositioning your cameras or your router so that they are within adequate range of each other. 

Additionally, you can also consider buying a network booster in case you can’t reposition the cameras. Network boosters provide an enhanced range for your wifi connection.

Power Cycle the Router

Restarting your devices occasionally will help clear any bugs or glitches in the device. 

If your router hasn’t been power cycled in a while we suggest you restart it. It will help it refresh its connection and ensure a stronger, more stable, and faster network.

This step is proven to be an effective fix for most issues with the network, including the Blink network request failed issue.

To power cycle your router or modem:

  1. Unplug the power cord from the router. 
  2. Wait for a couple of minutes.
  3. Plug the power cord back in.
  4. Wait for the router to restart and re-establish its internet connection.

After restarting your router, connect to it again and see if the issue is resolved.

Power cycling your router will disrupt the internet connection to the devices that are currently connected to it. Power cycling your router will not clear any saved settings of the router.

Disable VPNs and Other Network Filters

If you are someone who uses VPN to connect to your network, the authentication failed message is most probably caused due to this. 

VPNs are an important tool in enhancing online privacy and security but they will sometimes interfere with the proper functioning of network-connected devices like Blink cameras. 

Here are some ways that VPNs can cause network issues and affect the proper functioning of devices:

  1. VPNs can cause a decrease in network reception and speed. Additionally, VPNs connect you to encrypted servers in different geographical locations, causing additional network lags and hops leading to the authentication failed issue.
  2. VPNs mask the IP addresses of the devices connected to them. This becomes a problem when the Blink servers try to communicate with your device using the previous IP thereby causing the authentication failed issue.
  3. VPNs also introduce additional firewalls and network filters that interfere with the proper working of the Blink camera.

Try accessing your cameras after disconnecting from your VPN. 

To disconnect from your VPN in Windows (in case you access the Blink app on PC):

  1. Navigate to the VPN app.
  2. Click on the Disconnect or Turn off option.

To disconnect from your VPN in MacOS:

  1. Go to the Menu bar.
  2. Click on the VPN icon.
  3. Select the Disconnect or Turn Off option. 

To disconnect from your VPN on Mobile devices:

  1. Navigate to the VPN app or Device settings. 
  2. Find and click on the  Disconnect or Turn off option under VPN.

Once you are disconnected from the VPN, try accessing your cameras again. The authentication failed message should not pop up anymore.

If it is absolutely necessary to access your Blink cameras while still being connected to VPN, then make sure that the VPN server that you are using is in the same time zone as yours. This will enable you to access the Blink cameras while still being connected to VPN.

Check for Server Downtime

It is sometimes possible that the authentication failed issue arises due to a server issue on the part of Blink.

It is possible that the Blink servers are taken down for maintenance or due to technical issues. This can prevent users from accessing their Blink cameras.

The servers might face a software or hardware issue owing to which they will be unable to send a reply to their clients resulting in the authentication failed problem.

If this is the case, then there is very little to be done from your side. All you can do is patiently wait for the Blink servers to be back up again. 

To check if the server is down, you can go to the official Blink status page. Here you will be able to see possible server downtimes or other possible issues with the servers.

Additionally, you can go to other third-party server downtime tracking sites such as Downdetector where you will be able to see the status of various servers including Blink. 

These sites provide a comprehensive view of the different servers and the issues faced by other users from which you can determine whether the server is down or not.

If the server is down, we are sure that the Blink team is already on it to bring the server back up again.

Check and Refresh the Login Credentials

Blink App Login page

If you faced the authentication failed message while trying to log in to the Blink account, then it's possible that you entered the wrong email address or password.

Entering the wrong maid ID or password will cause the Blink app to deny you access to the cameras. 

Possible ways for this to happen are:

  1. Incorrect password - make sure that you are entering the right password for your account. The passwords are case-sensitive and make sure that you type in the correct special characters if any. Double-check to make sure that you didn’t make any typos. 
  2. Incorrect Email address - Make sure that you are using the right mail id for your account. Ensure that there are no errors in the mail address and also that you accidentally didn’t swap between your mail ids. 

If you suspect that you entered the wrong password, then it's better you use the forget password option provided in the app or the website. You can use this option to reset your password.

Resetting your password once in a while will help enhance the privacy and security of your account and at the same time help refresh your credentials. 

To reset and refresh your login credentials:

  1. Log out of the Blink account from your app or website 
  2. On the sign-in page, enter your registered email address and click on the Forgot password option
  3. A password reset link will be sent to your registered email address. (make sure to check junk and spam folders)
  4. In the mail, find the link to reset your password. 
  5. Click on the link and follow the instructions to reset and enter your new password
  6. Your account password should be reset now

Once the password is reset, navigate back to the Blink app or website and log in to your account using the new password. You should be able to access your cameras now.

Cannot Access Live View of Blink Cam: How to Fix

Blink live view icon

Blink cameras have an amazing feature called Live View that enables you to see the live video feed from your camera using the Blink app.

This is extremely helpful when you need to check on things if the camera’s motion sensors are triggered.

And like any feature, the Live View is not without its flaws. Sometimes a software glitch or a bug will render the Live view feature inaccessible. 

Just like the “Authentication failed” issue, an adequate internet speed is also necessary for accessing the live view feature.

Using a VPN will also render the feature not usable, try accessing it after disabling the VPN. 

Check and see whether the Blink servers are up and running. If the servers are down, the cameras will be unable to query the request to the user.

You can also try power cycling your mobile device and Blink camera. Power cycling your device will help it reload its firmware, refresh its connection and help get rid of any bugs or glitches.
