FIDO authenticator Trussed® app.

Built with Trussed.

As used in the SoloKeys Solo 2 and Nitrokey 3.



For attestation to work, the authenticator's state needs to be provisioned with a batch attestation key and certificate. They are expected in files /fido/sec/00 and /fido/x5c/00, respectively.

In the context of the SoloKeys Solo 2, "secure" devices are pre-provisioned; for "unlocked" devices, if the firmware contains the provisioner app, this can be done with the CLI:

solo2 pki dev fido batch.key batch.cert
solo2 app provision store-fido-batch-key batch.key
solo2 app provision store-fido-batch-cert batch.cert
