Secure Your Users One Email at a Time
Protect account access and user data with frictionless, time-sensitive email OTPs. Perfect for signups, secure logins, and fallback authentication.
Why Use Email OTP?
Ideal for Account Creation
Not all users share phone numbers. Email OTP is perfect for verifying identity during signups, especially in B2B, SaaS, and edtech.
Fallback for SMS & 2FA
If SMS fails due to DND, delivery issues, or international numbers, email steps in to complete the verification loop.
Better for Secure Workflows
Email is more suited for login verification in compliance-heavy industries where mobile use is restricted.
Consistent & Cost-Effective
Email works globally, doesn’t rely on carrier infrastructure, and comes at a lower cost per interaction.
