How to use the Kraken mobile app to set up biometric login?

Biometric Login Configuration Steps

1. Launch the official Kraken mobile application after successful installation and account verification.

2. Navigate to the Settings menu from the profile icon located in the top-left corner of the app interface.

3. Select Security Settings, then locate and tap the toggle labeled Biometric Login.

4. Confirm your current PIN or password when prompted to authorize the change.

5. Grant system-level permission for fingerprint or facial recognition access as instructed by your device’s native prompt.

Device Compatibility Requirements

1. Android devices must run Android 6.0 (Marshmallow) or higher with a registered biometric sensor enabled in system settings.

2. iOS devices require iOS 13.0 or later and must have Face ID or Touch ID configured under Settings → Face ID & Passcode or Touch ID & Passcode.

3. The Kraken app version must be 5.12.0 or newer to support biometric authentication features.

4. Devices rooted or jailbroken are explicitly blocked from enabling biometric login due to security policy enforcement.

5. Users with multiple biometric profiles on one device will only be authenticated using the primary enrolled method.

Authentication Behavior During Transactions

1. Biometric verification is triggered automatically before executing any withdrawal, API key creation, or KYC document upload.

2. When placing limit or market orders exceeding $10,000 USD equivalent, the app requires re-authentication via biometrics even if session remains active.

3. Failed biometric attempts beyond three consecutive occurrences lock the feature for 15 minutes and revert to password fallback.

4. Each biometric confirmation generates an immutable timestamped log entry visible in the Security Activity section of the app.

5. Session timeouts remain unchanged at 15 minutes of inactivity; biometric login does not extend this duration.

Recovery and Deactivation Procedures

1. To disable biometric login, users must enter their full account password—not just the device unlock code—in the Security Settings panel.

2. If biometric sensors become unavailable due to hardware failure, the app displays a persistent banner advising immediate password reset through email recovery flow.

3. Changing device passcode or unlocking pattern on Android triggers automatic deactivation of biometric login until manually re-enabled.

4. iOS users who reset Face ID or Touch ID settings must reconfigure Kraken’s biometric access separately within the app.

5. Enterprise-managed devices governed by MDM policies may suppress biometric prompts entirely based on organizational security profiles.

Frequently Asked Questions

Q: Does Kraken store biometric data on its servers?No. Kraken never receives or stores raw biometric templates. All processing occurs locally on the user’s device using OS-native secure enclaves.

Q: Can I use biometric login while connected to a public Wi-Fi network?Yes. Biometric authentication operates entirely offline and does not transmit biometric information over the network.

Q: Why does the app ask for my password after enabling biometric login?The initial setup requires password verification to confirm ownership. Subsequent actions rely solely on biometric input unless security thresholds are exceeded.

Q: Is biometric login available for Kraken Futures accounts?Yes. Biometric login applies uniformly across all Kraken product lines including Spot, Margin, Futures, and Staking interfaces within the same app instance.
