How to enable Face ID for Phantom mobile? (App Security)

Enabling Face ID in Phantom Mobile

1. Open the Phantom mobile application on your iOS device.

2. Navigate to the Settings menu by tapping the gear icon located in the top-right corner of the wallet’s home screen.

3. Scroll down and select Security & Privacy from the list of options.

4. Toggle on Biometric Authentication — this activates the system-level prompt for Face ID verification before accessing sensitive wallet functions.

5. Confirm your choice by authenticating with your current Face ID scan when prompted.

Supported Device Requirements

1. Face ID functionality is only available on iPhone X and later models running iOS 15 or higher.

2. The device must have Face ID properly configured under iOS Settings > Face ID & Passcode.

3. Phantom mobile does not support fallback to Touch ID even on compatible devices — Face ID is the sole biometric option for authentication.

4. Jailbroken devices will not allow Face ID integration due to iOS security restrictions enforced at the operating system level.

Actions Requiring Face ID Verification

1. Unlocking the Phantom wallet after the app has been backgrounded for more than 60 seconds.

2. Signing any transaction involving token transfers, NFT mints, or smart contract interactions.

3. Accessing the seed phrase backup screen or initiating a wallet recovery process.

4. Changing critical security settings such as disabling biometric authentication or modifying wallet permissions.

Disabling Face ID Authentication

1. Go to Settings > Security & Privacy within the Phantom mobile app.

2. Tap the toggle next to Biometric Authentication to switch it off.

3. You will be required to enter your wallet passcode one final time before the setting deactivates.

4. Once disabled, all future access to protected features will rely solely on the wallet passcode.

Frequently Asked Questions

Q: Does Phantom store my Face ID data?No. Phantom never receives or stores biometric data. Face ID processing occurs entirely within Apple’s Secure Enclave and is handled by iOS, not the app.

Q: Can I use Face ID while wearing sunglasses or a mask?Face ID may fail under such conditions depending on model generation. iPhone 12 and newer support mask-aware authentication, but Phantom does not override or modify iOS behavior — success depends on native system capability.

Q: Why does Face ID prompt appear even after I just used it?This occurs when the app detects a potential session reset, such as switching accounts, force-closing the app, or changing network environments. Each context shift triggers re-authentication.

Q: Is Face ID enabled by default after installing Phantom?No. Biometric authentication must be manually activated in Settings > Security & Privacy. New installations start with passcode-only protection until explicitly configured.
