Mobile App — Western Alliance Bank Business on iOS and Android

The Western Alliance Bank Business mobile app brings commercial banking to iOS and Android with the same security baseline as the online banking web portal. Treasurers approve pending wires with Face ID, deposit checks by capturing images from the camera, monitor consolidated cash positions, and respond to push alerts from anywhere. Biometric sign-in replaces password entry after enrollment, and high-risk actions still prompt step-up multi-factor authentication.

Mobile device management integrations let enterprise customers distribute the app through their MDM console and enforce device-level policies like jailbreak detection, screen recording blocking, and remote wipe. The app shares a single backend with the web portal — approvals made on mobile clear pending queues on the desktop in real time, and balance changes reflect immediately across surfaces.

Mobile Features at a Glance

What you can do from your phone — grouped by frequency of use.

Balance Checks

Consolidated view across every account. Tap to drill into transactions, filter by date or category, and pull statements. Home screen widgets (iOS and Android) surface balances without opening the app.

Mobile Check Deposit

Capture front and back images of endorsed checks. OCR reads the MICR line, verifies the 'For Mobile Deposit Only' endorsement, and submits for next-day processing. Daily and monthly limits vary by account history.

Payment Approvals

Push notifications surface pending ACH batches, wires, and positive pay exceptions. Approve with Face ID or fingerprint. Reject with a reason code that routes back to the initiator.

Push Alerts

Balance thresholds, large transactions, fraud indicators, new device logins, MFA failures, and relationship manager messages delivered as native push. Configure categories in settings. Cross-reference alerts for delivery channels.

Biometric Login

Enable Face ID, Touch ID, or Android fingerprint in settings after initial enrollment. Biometric data stays on device in the secure enclave. Replaces password but does not bypass MFA for high-risk actions.

Relationship Manager Chat

Secure in-app messaging with your dedicated relationship manager. Messages route to the assigned commercial banker with email backup. Attachments support PDF, JPG, and PNG up to 10 MB.

Security Inside the Mobile App

Jailbreak detection, TLS pinning, and secure-enclave biometrics defend the mobile surface.

Device Attestation

At launch, the app runs device attestation — jailbreak detection on iOS, root detection on Android, and integrity checks on the binary signature. Failed attestation blocks sign-in with an error that includes remediation guidance. TLS certificate pinning prevents man-in-the-middle interception on untrusted networks, such as public Wi-Fi at a coffee shop or airport lounge.

Biometrics and Secure Enclave

Biometric data never leaves the device. The app asks the operating system for a yes/no biometric match, and the OS returns a signed assertion from the secure enclave. Disabling biometrics at the OS level, adding a new fingerprint, or wiping the device revokes the stored credential and forces re-enrollment. Biometric replaces password entry; it never bypasses MFA for high-risk actions like wire release.
