Auto-expiry
OTPs expire by default
No storage
Codes are never logged
Security
Secure by default.
Security is not an add-on. Rate limiting prevents brute force attacks. Automatic expiration ensures OTPs cannot be reused. Codes are never stored in logs or databases.
Every request is authenticated. Every response is signed. Every connection is encrypted. We handle the security infrastructure so you can focus on building.

NepalOTP runs on prepaid credits. Your balance is deducted only for successful OTP sends and approved transactional messages. Sandbox testing stays free.
Successful sends only
BilledOTP + transactional messages deduct from balance.
Sandbox + failed validation
Not billedTest freely and only pay on delivery success.
