ABA Business

The ABA Business app is a secure, mobile-friendly companion for ABA Business Web users that replaces the previous 2FA authenticator. It enables secure logins, swift approval or rejection of payment and non-financial instructions, account balance and transaction history views, card management (freeze, block, limits), exchange rate lookups, and expense tracking — all with real-time alerts and an intuitive interface for uninterrupted business banking.

Available exclusively to ABA Business members, setup links your mobile device to your ABA Business profile via a QR code generated in the web app. The app is free to use and built with multi-layer, military-grade encryption — it stores no account or transaction data locally and digitally signs activity to prevent interception or tampering. ABA will never ask for your temporary/permanent password, 6-digit PIN, SMS OTP, or card/ATM PIN.
