SignOps is a cloud-based API tailored for developers looking to incorporate push messaging and sign-in processes into their web and mobile applications. It allows developers to link devices to current user IDs, dispatch push notifications to users or specific topics across Android, iOS, and web platforms, as well as schedule messages, utilize templates, and track delivery metrics. Additionally, the service facilitates phone-based login verifications that include number matching and biometric checks, enables passkey sign-ins on a client's domain, offers TOTP authenticator codes along with backup options, and supports email one-time passwords. Integration with existing backends and identity providers is made seamless with REST endpoints, server SDKs, mobile and web SDKs, a collaborative team dashboard, and signed webhooks. SignOps is specifically crafted for developers and teams focused on creating applications that require effective notification systems, passwordless authentication, or enhanced sign-in security measures. With its multifaceted features, SignOps aims to streamline the user experience while bolstering application security.
