SMS OTP is expensive at scale and trivially easy to compromise. Passkeys+ is a drop-in replacement for every OTP in your authentication stack, no rebuild required.
At high volume, SMS OTP costs add up fast. More critically, it's not secure. SIM swap fraud, SS7 interception, and social engineering make OTP the weakest link in any authentication stack.
Attackers port your user's number and receive the OTP.
Network-level vulnerabilities expose SMS in transit.
Users tricked into sharing codes they shouldn't.
Passkeys+ replaces OTP with a device-bound biometric. Authentication is instant, cryptographically verified, and tied to the physical device, not a phone number.
Across login, step-up, and transaction flows.
No interception vector, no social engineering exposure.
Banks, fintechs, and telecoms running high-volume authentication.
OTP replacement means substituting SMS one-time passwords with a more secure and cost-effective authentication method. SMS OTPs are vulnerable to SIM swap fraud, SS7 interception, and social engineering attacks. They also carry a per-message cost that scales linearly with transaction volume. Replacing OTP with device-bound passkeys eliminates these vulnerabilities and costs while improving the user experience.
Passkeys use asymmetric cryptography tied to the user's physical device. Instead of sending a shared secret over an insecure SMS channel, the authentication happens locally on the device using a biometric or device unlock. The private key never leaves the device, so there is nothing to intercept, phish, or steal. This makes passkeys a direct, drop-in replacement for every SMS OTP in your authentication stack.
Yes. Passkeys+ is designed as a drop-in replacement that integrates with your existing authentication flows. It works across login, step-up, and transaction verification without requiring a full rebuild of your identity stack. Ideem supports banks, fintechs, and telecoms running high-volume authentication at scale.
