Retail Banking Login with Silent Authentication
Potential Solution
To reduce friction during routine mobile banking logins while maintaining appropriate security controls, financial institutions can implement Vonage Verify Silent Authentication as the primary mobile-based possession signal within a broader multi-factor or risk-based authentication framework.
Note: Fallback channels can be any Verify workflow option (for example, SMS, Voice, WhatsApp, RCS, or Email). SMS and Voice are shown in this use case only as examples. For details, see Verify workflows.
Silent Authentication verifies SIM-to-device association via the mobile network in the background through the mobile carrier, enabling eligible customers to access their accounts effortlessly. OTPs remain available as a backup option and for higher-risk cases, ensuring security and continuity under various login conditions.
The following flow is our suggested method for implementation:
This adaptive approach improves login success rates and reduces friction without weakening security standards essential in financial services.
