Have you ever tried to use Samsung Pass to log in to one of your apps, only to be greeted by the message "Couldn‘t verify fingerprints. Try again later"? I‘ve been there, and it‘s incredibly frustrating!

As a tech geek and avid Samsung user, I rely on Samsung Pass daily to conveniently and securely log me in with just my fingerprint. So when it starts failing, it‘s a big productivity blocker.

After digging around forums, contacting Samsung support, and testing solutions, I‘ve figured out several effective ways to get Samsung Pass successfully verifying my fingerprints again.

In this comprehensive troubleshooting guide, I‘ll walk you through exactly why Samsung Pass can‘t verify fingerprints, the step-by-step fixes, and what to try if it still doesn‘t work. Follow along and we‘ll get Samsung Pass up and running again in no time.

Why Does Samsung Pass Fail to Verify Fingerprints?

Before we get to the solutions, it helps to understand the common reasons why Samsung Pass can‘t properly verify your fingerprints or facial recognition when you try to log in:

  • Connectivity issues – Samsung Pass requires an internet connection to verify your identity through Samsung servers. Weak WiFi, no signal, or a VPN being enabled can disrupt this connectivity.

  • Outdated app versions – Bugs in old versions of the Samsung Pass and Samsung Wallet apps can prevent successful fingerprint and face verification. Updates are key.

  • Biometric data changes – Your fingerprints and facial data change subtly over time. Samsung Pass can fail to verify outdated biometrics that haven‘t been re-registered.

  • Samsung server outages – Like any app, when the Samsung servers that Samsung Pass relies on have downtime, the app itself can‘t function properly.

  • Temporary software glitches – Sometimes Samsung Pass bugs or app crashes occur, causing failed verifications until fixed by a restart, cache clear, or update.

Now let‘s walk through the best troubleshooting steps to overcome each of these potential issues.

6 Ways to Fix "Couldn‘t Verify Fingerprints" in Samsung Pass

I‘ll share the methods that have worked for me and other Galaxy users based on extensive research and trial-and-error. Here are the 6 top ways to fix the Samsung Pass fingerprint verification failure:

  1. Check for and install Samsung Pass and Wallet app updates
  2. Switch from WiFi to mobile data
  3. Re-register your biometric data
  4. Restart your Samsung device
  5. Clear the Samsung Pass app cache/data
  6. Contact Samsung support

I‘ll go through each fix in detail so you can get Samsung Pass working perfectly again.

1. Check for App Updates

One of the easiest first steps is to check if your Samsung Pass and Samsung Wallet apps need updating. According to Samsung‘s own troubleshooting advisory, outdated app versions can prevent verification.

Here‘s how to update the apps:

  • Samsung Pass – Open the Galaxy Store app > Tap the 3 line Menu icon > Select "Updates" > Check for "Samsung Pass" update > Tap "Update" to install.

  • Samsung Wallet – Open Galaxy Store > Menu > Updates > Check for "Samsung Wallet" update > Tap "Update".

If no updates show as available, move on to the other troubleshooting fixes. But apps constantly receive improvements and bug fixes, so this simple update check is worth trying.

2. Switch From WiFi to Mobile Data

Connectivity issues account for many cases of Samsung Pass failing to verify fingerprints or face in my experience.

An easy way to test if this is the culprit is to switch the network that your phone is using:

  • Open your Notification panel by swiping down from the top of the screen.
  • Tap the WiFi icon to turn off and disable your WiFi connection.
  • Then tap the Mobile data icon right next to it to turn on mobile data.

Now try launching Samsung Pass and using your fingerprint to log in again.

If it works properly with mobile data but fails on WiFi, you can confirm your wireless network has connectivity problems disrupting the verification.

Sticking with mobile data is an easy fix in this case. You can also try disconnecting and reconnecting to your WiFi network or using a different network.

3. Re-Register Your Biometric Data

Your fingerprints and facial data naturally change gradually over time. Small cuts and cracks occur on fingers. Your look evolves if you gain or lose weight.

This can cause enrolled fingerprints and face scans to become outdated. Samsung Pass then fails to properly match them to verify your identity.

The solution is to re-register your latest biometric data in the Settings app:

  • Open Settings and tap "Biometrics and security."
  • Under Fingerprints, tap "Add fingerprint" to re-add each fingerprint you want to use with Samsung Pass.
  • For facial recognition, tap "Face recognition" > "Continue" and follow the prompts to re-scan your face.

Samsung Pass will then use your newest biometric data for verification, avoiding any mismatches from outdated scans.

4. Restart Your Samsung Device

Before getting too deep into troubleshooting, try restarting your Galaxy S22, S20 FE, or whichever Samsung device you use. A simple restart can clear up many app glitches and errors.

Here‘s how to quickly restart your phone:

  • Press and hold the Power button on the side to open the power menu.
  • Tap "Restart" to restart the phone.
  • The device will power off and boot back up, clearing any software gremlins.
  • Once restarted, open Samsung Pass and see if it now successfully verifies your fingerprint or face.

Restarting provides a clean slate for Samsung Pass, often resolving temporary failures like couldn‘t verify fingerprints. It‘s an easy fix to try first before more advanced steps.

5. Clear the App Cache and Data

If updating, changing networks, and restarting haven‘t fixed Samsung Pass biometric verification issues, take one more software troubleshooting step – clearing the app cache and data.

Here‘s how:

  • Open Settings and tap "Apps."
  • Tap the "See all apps" button if needed to see the full apps list.
  • Select the "Samsung Pass" app.
  • Tap "Storage."
  • Tap "Clear cache" and confirm by tapping "OK" to wipe the temporary cache files.
  • Then tap "Clear data" and confirm to reset the app data.
  • Restart your phone.
  • Re-set up your fingerprints/face in Samsung Pass.

This essentially resets Samsung Pass to a clean, fresh state which helps resolve many stubborn app problems. It has worked to fix couldn‘t verify fingerprints for myself and other Galaxy users with persistence verification failures.

6. Contact Samsung Support

If you still see the "couldn‘t verify fingerprints" message after trying all the troubleshooting steps, it‘s time to bring in help from the Samsung support team. Here are a few ways to contact them:

  • Live chat – I recommend using the Samsung Contact Page to initiate a live chat. You can describe your exact issue and all the attempted fixes.

  • Call support – You can also call Samsung support using the contact number for your country provided on that same page. Speaking directly with a support rep can help troubleshoot.

  • Twitter/Facebook – Reaching out publicly via Samsung‘s Twitter account @SamsungSupport or Facebook page tends to get prompt responses too.

  • Samsung Members app – Use the Samsung Members app pre-installed on your phone to submit a support request under "Get help."

Samsung support can further diagnose your specific case, potentially fix account or server issues on their end, and initiate a warranty repair if needed.

What If Samsung Pass Still Doesn‘t Work?

Hopefully using one or more of the 6 troubleshooting methods resolved your "couldn‘t verify fingerprints" issue and got Samsung Pass successfully verifying your biometrics again. But I know how stubborn some tech problems can be.

If you continue having no luck with fingerprint or facial verification in Samsung Pass, here are a couple fallback options:

  • Disable Samsung Pass – As a temporary workaround, you can turn off Samsung Pass entirely until a permanent fix is found. Go to Settings > Biometrics and security > Samsung Pass > Toggle off.

  • Use alternative apps – Plenty of password manager apps like LastPass and Dashlane can store passwords and log you into apps/sites. You lose Samsung Pass convenience but retain auto-fill.

  • Wait for updates – If Samsung is aware of a wider server outage or bug causing verification failures, stay patient for Samsung Pass app updates that will patch it.

While super handy, Samsung Pass isn‘t 100% flawless. But some simple troubleshooting should get it working properly again soon. Let me know if these tips fixed your "couldn‘t verify fingerprints" issue!
