SYNOPSIS

int
fido_dev_enable_entattest(fido_dev_t *dev, const char *pin);

int
fido_dev_toggle_always_uv(fido_dev_t *dev, const char *pin);

int
fido_dev_force_pin_change(fido_dev_t *dev, const char *pin);

int
fido_dev_set_pin_minlen(fido_dev_t *dev, size_t len, const char *pin);

DESCRIPTION

The fido_dev_enable_entattest() function enables the Enterprise Attestation feature on dev. Enterprise Attestation instructs the authenticator to include uniquely identifying information in subsequent attestation statements. The pin parameter may be NULL if dev does not have a PIN set.

The fido_dev_toggle_always_uv() function toggles the “user verification always” feature on dev. When set, this toggle enforces user verification at the authenticator level for all known credentials. If dev supports U2F (CTAP1) and the user verification methods supported by the authenticator do not allow protection of U2F credentials, the U2F subsystem will be disabled by the authenticator. The pin parameter may be NULL if dev does not have a PIN set.

The fido_dev_force_pin_change() instructs dev to require a PIN change. Subsequent PIN authentication attempts against dev will fail until its PIN is changed.

The fido_dev_set_pin_minlen() function sets the minimum PIN length of dev to len. Minimum PIN lengths may only be increased.

Configuration settings are reflected in the payload returned by the authenticator in response to a fido_dev_get_cbor_info(3) call.
