Out-of-Band Authentication
Enjoy Secure Online Transactions
Habib Bank AG Zurich has introduced Out-of-Band (OOB) Authentication, a powerful security enhancement designed to protect your online Visa card transactions.
With OOB Authentication, you no longer need to rely solely on One-Time Passwords (OTPs) sent via SMS or email. Instead, you can securely approve your online transactions using the HBZ Mobile Banking App (recommended method).
