What it provides
The verification layer, without unnecessary complexity.
A focused authentication service for applications that need secure OTP and TOTP verification.
Authenticator TOTP
Enroll and verify standard time-based codes compatible with modern authenticator apps.
Application isolation
Every application receives independent credentials, configuration and authentication controls.
Abuse protection
Rate limiting, recipient restrictions and verification-attempt controls protect the authentication flow.
Privacy-conscious logs
Operational activity can be reviewed without storing OTP codes, client secrets or other unnecessary sensitive values.
Simple integration
Small HTTP APIs make verification easy to add to server-side applications without a large authentication framework.
Interactive example
A familiar verification experience.
Generate a demonstration code to see the basic flow. This example is entirely local to your browser and does not call the real authentication API.
