Developer Overview
What you need depends on what you are building. Most integrations need no Seedkeeper code at all - here is how to tell which case you are in.
Device Capabilities
The complete technical profile of Seedkeeper PRO: AAGUID, CTAP versions, algorithms, extensions, options, limits and transports. Raw metadata.
WebAuthn Quickstart
Add passkey support with standard WebAuthn. Registration, authentication, the parameters that matter, and the mistakes that break hardware keys.
FIDO2 Integration Guide
Attestation, AAGUID allowlists, credProtect, hmac-secret and enterprise policy. The parts of FIDO2 that go beyond a basic WebAuthn integration.
Python Library and CLI
seedkeeper-manager configures the FIDO2 and OTP applets from Python or the command line. What it is for, and where provisioning at scale needs care.
Mobile SDKs
iOS and Android SDKs for talking to a Seedkeeper PRO over NFC, with the reference apps that use them. Forks of the Yubico mobile SDKs.
Repositories
Every Seedkeeper repository, what it contains, and which one to read for a given problem. All AGPLv3.
