5 Steps to Enable Biometric Wallet Access
Enable fingerprint or Face ID for your digital wallet in five steps: verify device, set passcode, allow biometrics, and adjust locks.
Biometric authentication makes accessing your digital wallet faster and more secure. Instead of entering a password, you can use your fingerprint or face to verify your identity. Here's how to set it up in five simple steps:
- Check Compatibility: Ensure your device has biometric hardware (e.g., Face ID or fingerprint scanner) and your wallet app supports it. Update your app and confirm a backup passcode is set.
- Access Wallet Settings: Open your wallet app, navigate to the settings menu, and find the security options.
- Set a Passcode: Create a strong passcode as a backup for biometric authentication.
- Enable Biometrics: Turn on biometric authentication in your wallet's security settings and grant necessary permissions.
- Adjust Settings: Fine-tune features like auto-lock timers for added convenience and security.
Biometric data stays on your device and is never shared with wallet apps, ensuring privacy. If issues arise, clean your sensor, re-register your biometrics, or restart your device. By following these steps, you can enjoy a secure and hassle-free wallet experience.
5-Step Process to Enable Biometric Wallet Access
Step 1: Verify Device Compatibility and Requirements
Make sure your smartphone has the necessary biometric hardware and that your wallet app supports it. This step helps avoid setup issues.
Check for Biometric Hardware
Your phone must have the sensors needed for biometric authentication. For iPhone users, head to Settings and look for either "Face ID & Passcode" (on newer models like iPhone 12, 13, and 14) or "Touch ID & Passcode" (on models with a home button). On Android, go to Settings > Security & privacy > Device unlock to check for Fingerprint or Face Unlock options. If you use a Samsung device, check Settings > Biometrics and security for available features.
Some wallet apps require advanced biometric capabilities. For instance, Bitwarden explains that "On Android, Bitwarden requires your biometric factor to be Class 3". Similarly, Google Wallet won’t work with Class 1 or Class 2 biometric unlocks or screen locks like Smart Unlock or Knock to Unlock. If you see an error like "Biometric identification is disabled or unavailable", it’s likely due to incomplete configuration in your device’s settings.
Once you confirm your device hardware meets the requirements, update your wallet app to ensure you have the latest biometric functionality.
Update Your Wallet App
Use the official App Store or Google Play Store to update your wallet app. Updates often add or improve biometric features. For example, Tangem introduced an update in early 2023 that allowed users to view balances and switch wallets using only Face ID or a fingerprint. Previously, users had to tap a physical card and enter an access code for every interaction.
After updating, make sure your wallet is secured with a backup passcode.
Confirm Backup Security Is Set Up
Set up a backup passcode or PIN and store your recovery phrase securely offline. For better protection, choose a 6-digit code or an alphanumeric password. Trust Wallet emphasizes, "Always back up your recovery phrase before setting up the passcode. If you forget your passcode, you'll need this phrase to restore your wallet after reinstalling the app". Keep in mind, Trust Wallet locks completely after five incorrect passcode attempts, requiring a full reinstallation and recovery with your backup phrase.

Step 2: Open Wallet Settings
Once you've confirmed compatibility, the next step is to enable biometric authentication through your wallet's settings.
Launch the App and Access Settings
Start by opening your digital wallet app and finding the settings menu. Typically, this is represented by a gear icon, a menu icon (three horizontal lines), or a "More" button. Depending on the app, the settings icon might be located in the top-right corner, top-left corner, or as part of a bottom navigation bar.
For example:
- Trust Wallet: The settings tab is located in the bottom-right corner.
- Atomic Wallet: You'll find a "More" button in the bottom navigation bar.
Once inside the settings menu, proceed to the security options to continue the setup process.
Locate Security Options
In the settings menu, look for a section labeled "Security", "Security Settings", or something similar, such as "Passcode & Face ID/Touch ID." This is where you'll find the biometric authentication settings. Some wallets may require you to enable Two-Factor Authentication (2FA) or set up a local passcode before the biometric toggle becomes available. If biometric options don't appear, ensure that your phone's Face ID or fingerprint scanning is activated - otherwise, you might encounter an "unavailable" error message.
In February 2025, Trust Wallet enhanced its security protocols. Users are now directed to the "Settings" tab in the bottom-right corner to manage biometric settings. Additionally, the app requires a six-digit passcode as a fallback. A new safeguard locks the app entirely after five incorrect attempts, requiring the recovery phrase to regain access.
Step 3: Set Up a Passcode
Once you've accessed your wallet's security settings, it's time to set up a passcode. This step is essential because most digital wallets require a passcode before enabling biometric authentication, like Face ID or fingerprint scanning. The passcode acts as a backup to authorize sensitive actions - such as sending funds or changing security settings - if your biometric sensor isn't available or doesn't work properly. It's your safety net for keeping access to your wallet secure.
Choose a Strong Passcode
When creating your passcode, aim for something that's easy for you to remember but difficult for others to guess. Many wallets default to a 6-digit numeric code, but some let you customize it further with a shorter PIN or an alphanumeric passcode for added protection. Avoid predictable sequences like "123456", repetitive numbers, or anything tied to personal information, like birthdays or names. Instead, think about using a passphrase - something like "Access2026!" - to make your wallet even more secure.
After deciding on your passcode, you'll need to confirm and save it.
Confirm and Save Your Passcode
To finalize, re-enter your passcode to confirm it. This step locks in your wallet's security and enables biometric features. Before proceeding, make sure you've backed up your recovery phrase - wallet providers can't reset your passcode if you lose it. After confirmation, your wallet may suggest additional security settings, such as adjusting auto-lock timers or enabling biometric options, which you can configure next.
Step 4: Turn On Biometric Authentication
Once you've confirmed your passcode, it's time to enable biometric authentication. This step links your wallet app to your device's security features, like Face ID, Touch ID, or a fingerprint scanner. You'll need to grant permissions and ensure everything is working as expected.
Select Your Biometric Method
Head back to your wallet's security settings and look for options such as "Passcode and Touch/Face ID", "Security", or "Account Security." You'll usually find a toggle next to phrases like "Unlock with Face ID" or "Enable Fingerprint." Switch it on, and when prompted, re-enter your passcode to proceed.
The biometric options you'll see depend on your device's hardware. For instance, if your phone supports Face ID and it's already set up, that option will be available. On Android devices with fingerprint scanners, you'll see fingerprint-related options instead.
Allow Device Permissions
After enabling the feature, your device will display a pop-up asking for permission. Tap "Allow" to connect your wallet app to your device's secure hardware. This action ties the app to the Secure Enclave (on iOS) or the Trusted Execution Environment (on Android).
"Bitwarden never receives your biometrics data, because the feature uses native APIs to perform the validation on your local device." – Bitwarden
Your biometric data stays private and never leaves your device. The wallet app only receives a simple "success" or "failure" signal from your phone's hardware. If you see an error like "Biometric identification is disabled or unavailable", check that you've already registered your fingerprint or face in your device's Settings app. Also, ensure your biometric setup is functioning properly.
Test the Setup
Finally, verify that biometric authentication is working as it should. Close and reopen the app. You should see a prompt for your fingerprint or face.
Try unlocking the app using your biometric method. If it works without a hitch, you're good to go! If the option appears greyed out or doesn't activate, log in manually with your passcode. This might trigger the biometric prompt, allowing you to test it again. Keep in mind that some wallet apps may request biometric authentication every time you open them, while others only do so after a period of inactivity.
Step 5: Adjust Settings for Convenience and Security
Once you've set up biometrics and a passcode, fine-tuning your wallet's settings can help strike the right balance between ease of use and protection. These adjustments ensure your wallet stays secure while remaining practical for everyday use.
Configure Auto-Lock Timer
An auto-lock timer is essential for protecting your wallet when it's left unattended. Most wallet apps let you choose how quickly the wallet locks, with options ranging from immediate locking to delays of a minute or more. For public or busy environments, stick with immediate locking or a very short delay to minimize risks. Additionally, many wallets allow you to require biometric authentication for approving transactions. This feature adds an extra safeguard, ensuring that only you can authorize outgoing transfers without making the process overly cumbersome.
Review Your Settings Regularly
Security isn't a one-and-done task - it requires regular check-ins. Take time to review your wallet's settings, usually located under "Security" or "Passcode & Face ID/Touch ID", to confirm everything is working as intended. If your biometrics aren't functioning properly, try toggling the feature off and back on again, or restart your device to reset the connection.
It's also wise to update your passcode periodically. This ensures you always have a reliable backup in case biometric authentication fails or your device restarts. And don't forget to keep your recovery phrase stored securely offline - it’s your ultimate safety net.

Biometrics vs Passcode-Only Access
Biometric authentication relies on "something you are", like a fingerprint or facial recognition, while passcodes depend on "something you know", such as a PIN. This difference gives biometrics a clear edge in many scenarios. For instance, biometrics reduce the risk of someone spying on you while you enter a PIN and can help block phishing attempts that trick users into revealing their passcodes.
| Feature | Biometric Authentication | Passcode-Only Access |
|---|---|---|
| Security Type | Identity-based (Physical presence) | Knowledge-based (Memorized secret) |
| Access Speed | Near-instant (~0.5 seconds) | Slower (Manual entry) |
| Remote Attack Risk | Extremely low (Requires physical body) | Higher (Prone to phishing and social engineering) |
| Public Vulnerability | Resistant to shoulder surfing | Vulnerable to visual observation |
| Brute-Force Risk | Low (Hardware lockouts after failed scans) | Higher (Susceptible to systematic guessing) |
Biometric systems are also highly accurate, with modern sensors having a false acceptance rate of just 0.001% - a 1 in 100,000 chance of error. By 2025, 34% of crypto wallets are expected to integrate biometric features, catering to the growing demand for secure yet convenient access. Plus, the speed is hard to beat: biometric unlocking averages just 0.5 seconds compared to the time it takes to manually enter a 6–12 digit PIN.
If your biometric access isn’t working as intended, there are simple fixes to address common issues.
Common Problems and Solutions
Failed scans are a frequent problem. Start by cleaning the biometric sensor; dirt, smudges, or oils can interfere with its accuracy. If the issue continues, try turning the biometric feature off and back on or re-register your fingerprint or face scan in your device's settings.
Sometimes, biometric access might temporarily disable itself. This often happens after changes to your device’s security settings, like adding a new fingerprint, as a precaution against unauthorized access. A quick reboot followed by re-enabling the biometric feature usually resolves this. For users of certain Samsung devices, both Face ID and fingerprint settings may need to be configured under the "Biometrics and security" menu before the feature works properly.
Conclusion
Using biometric authentication for your digital wallet strikes the perfect balance between security and convenience. By following five straightforward steps - verifying compatibility, accessing settings, setting a strong passcode, enabling biometrics, and fine-tuning security - you can safeguard your wallet against unauthorized access.
