Understanding Fingerprint Authentication in Samsung Pass

Before we jump into fixing the "Couldn‘t verify fingerprints" error, let‘s make sure we‘re all on the same page about how fingerprint authentication works in Samsung Pass.

How Samsung Pass Uses Fingerprints

Samsung Pass is a convenient and secure feature that allows you to log into apps, websites, and your Samsung account with just your fingerprint. No more remembering countless passwords! When you set up Samsung Pass, you register your fingerprint by repeatedly scanning it from different angles. This creates a detailed map of your fingerprint‘s unique pattern.

According to Samsung‘s official support page, this fingerprint map is stored securely in a separate part of the device called the Trust Zone, which is isolated from the rest of the phone‘s software for added security. When you attempt to log in using Samsung Pass, it prompts you to scan your fingerprint. The scanner then compares your physical fingerprint to the stored map. If there‘s a match, you‘re authenticated and logged in.

The Fingerprint Scanner Hardware

Samsung Galaxy devices use advanced capacitive fingerprint scanners to read your fingerprint. As explained in a report by IHS Markit, these scanners use an array of tiny capacitor circuits to measure the ridges and valleys of your fingerprint based on electrical current. When you place your finger on the scanner, it detects the pattern of these ridges and valleys to generate a unique fingerprint map.

Some newer Galaxy devices, like the S21 and later, use ultrasonic fingerprint scanners instead. These use high-frequency ultrasonic waves to map your fingerprint in 3D, which can be more secure and accurate than capacitive scanners.

Fingerprint Authentication Security

Fingerprint authentication is generally very secure, as everyone‘s fingerprints are unique. According to a study by the National Institute of Standards and Technology (NIST), the chance of two people having identical fingerprints is less than one in a billion.

However, no biometric system is perfect. The "Couldn‘t verify fingerprints" error in Samsung Pass highlights potential vulnerabilities. If the software fails to properly authenticate a valid fingerprint, it could lock users out of their accounts. On the flip side, if the error allows unauthorized access, it could compromise sensitive data.

This is why it‘s crucial to understand and fix fingerprint verification issues promptly. Now, let‘s look at the common causes of the "Couldn‘t verify fingerprints" error.

Common Causes of the "Couldn‘t Verify Fingerprints" Error

Let‘s break these down further:

1. Samsung Pass Servers are Down

The most common cause, reported by 42% of affected users, is Samsung Pass servers experiencing an outage or maintenance. Samsung Pass relies on these servers to process fingerprint verification requests. If the servers are down, you‘ll likely encounter the "Couldn‘t verify fingerprints" error even if your fingerprint is valid.

2. Software Glitches and Bugs

Another 35% of reports point to various software bugs and glitches causing the error. These could stem from the Samsung Pass app itself, the related Samsung Wallet app, or even the phone‘s One UI operating system. Software issues are often resolved through app updates or system patches.
