Do I need to configure APNs, FCM, and VAPID separately?
Yes, you provide your platform credentials in the Zyphr dashboard (APNs certificate/key, FCM service account, VAPID keys). After that, Zyphr handles routing to the correct platform based on the device token.
How does device token management work?
Zyphr provides client SDKs that handle token registration and refresh automatically. When a token expires or becomes invalid, it is removed from the user's device list. Users can have multiple devices registered simultaneously.
Can I send push notifications based on auth events?
Yes. Zyphr can trigger push notifications from auth events like new login from an unrecognized device, MFA challenges, or account security alerts — all without writing integration code.
What is the delivery latency?
Zyphr delivers push notifications to the platform provider (APNs, FCM) within milliseconds. Actual delivery to the device depends on the platform provider and device connectivity.
