Having your Blink security cameras suddenly go offline without warning is incredibly frustrating. You rely on your Blink system to actively monitor your home, so any connectivity issues like sync module authentication failed require immediate troubleshooting.
In this detailed guide, we’ll dig into the various causes of Blink sync module authentication problems and the steps you can take to diagnose and resolve them. With a few simple checks and resets, you’ll be back up and running.
What Causes Authentication Failure On Blink Sync Module?
When your Blink app fails to authenticate and connect with your sync module, there are a few common reasons:
- Incorrect Login Credentials – Double-check that you’re using the right username and password associated with your Blink account. With multiple users in a household, it’s easy to mix up credentials, leading to instant authentication failures.
- No Internet Connection – Your sync module requires a consistent internet connection via WiFi to communicate with Blink’s servers. Check for any internet or router outages in the area. Also, verify the sync module’s WiFi connection strength. In case your blink camera is not connecting to wifi, read this guide.
- Firmware Out of Date – An outdated version of firmware on either the Blink app, sync module, or cameras themselves can prevent proper authentication and connectivity. Always keep firmware updated. Updated Firmware prevents blink camera from being hacked.
- Sync Module Not Registered – Every new sync module must be registered to your Blink account through the app before use. If not properly registered, you’ll get authentication errors.
In that case, unregister your blink camera first and then register again.
- Too Many Login Attempts – As a security precaution, the Blink servers will temporarily lockout an account after several failed login attempts. Too many wrong passwords can trigger Blink Sync Module Authentication Failure.
- Power Interruption – The sync module needs constant power supply. Any outages or unplugging can severely impact connectivity and hence the sync module authentication failed error will come up. Use a backup power source if needed.
- Weak WiFi Strength – Low WiFi signals between your router and sync module lead to intermittent connectivity loss. Check your signal strength and move the module closer to the router.
As you can see, there are quite a few factors that can lead to Blink’s system being unable to authenticate and connect your account credentials to the sync module. But don’t worry – in most cases blink camera authentication failed error can be easily fixed with a few targeted troubleshooting steps.
Diagnosing the Underlying Issue Of Blink Sync Module Authentication Failure
When your Blink app shows the dreaded authentication failure notice, here are some steps to uncover the source of the problem:
- First, check the status light on the front of your sync module. A solid blue light indicates proper power and connection. If the light is off, try disconnecting and reconnecting the power cable or switching to a different AC outlet.
- Next, open the Blink app and go to the ‘Settings’ page. Try removing your sync module entirely and setting it back up again from scratch. This essentially re-registers it to your account.
- While in app settings, also check for any firmware updates for your sync module, cameras, or the app itself. Having outdated firmware can easily break connectivity so always keep devices updated.
- Consider connecting your phone directly to the sync module’s WiFi network to isolate connectivity issues. If you can connect directly, weak router signal strength may be the culprit.
- For persistent problems, perform a hard reset on the sync module using the pinhole button on the back. Press and hold for 15 seconds until the light blinks rapidly to factory reset.
- As a last resort, reach out to Blink’s customer support online or by phone. Provide your module serial number and account info so they can diagnose server-side issues.
- Taking the time to systematically diagnose the source of the authentication error will put you on the path to a quick resolution of the authentication failed error.
Preventing Authentication Failures On Blink Sync Module
Recovering from a temporary authentication failure is one thing, but you don’t want to deal with the same issues cropping up again and again. Here are some tips to avoid connectivity problems in the future:
- Maintain a strong and unique password for your Blink account. Enable 2-factor authentication for added security.
- Routinely check for and install firmware and app updates as soon as new versions are available. Turn on auto-update if possible.
- Optimize the position of your sync module centrally within your home with a line of sight to your router for the strongest WiFi signal.
- Connect your sync module to a backup power source to avoid any power interruptions. Consider a UPS battery backup.
- Take care to register any new Blink cameras or additional sync modules immediately after setup to your account.
- Use Blink’s desktop app for your computer to more easily monitor sync module connectivity status.
- If connectivity loss persists, contact Blink support to diagnose and resolve chronic authentication failure causes.
By taking preventative measures and addressing connectivity issues promptly, you can avoid the major headache of your Blink cameras constantly going offline and triggering authentication failures in your app. Maintaining reliable access to your Blink camera feeds is critical for home security peace of mind.
Frequently Asked Questions About Blink Authentication Failures
Here are answers to some common questions about troubleshooting Blink sync module authentication problems:
What happens when Blink sync module authentication fails?
The Blink app will lose connection to the sync module and cameras, rendering the sync module offline. You’ll get error messages when trying to view live feeds.
Why does my Blink keep losing authentication?
Frequent lost connections likely stem from subpar WiFi coverage, outdated firmware causing incompatibility issues, or problems with your Blink login credentials.
How can I tell if my Blink sync module is connected?
Check the status light on the module, or open the app to see if any cameras show as “offline”. All should say “online” when connected.
What is the best way to reset a Blink sync module?
The most reliable reset uses the small pinhole button on the back of the module. Press and hold for 10-15 seconds until the light blinks rapidly.
How do I avoid Blink authentication failure?
Frequently update firmware, position sync module centrally to maximize WiFi signal, use strong account passwords, and register new devices immediately.
Why does my Blink have no video after losing authentication?
Cameras will not record footage when disconnected from the sync module. Fix the connectivity issue first, then motion recordings will resume.
How can I minimize Blink sync module WiFi issues?
Optimize the location of your sync module, position it closer to your router on the same floor, and reduce interference from other WiFi networks or large appliances.
This was all on how to fix blink sync module authentication failed error. I hope that after following the mentioned troubleshooting methods, you will get your sync module and blink camera back up.
