The functions described in this page allow biometric templates on a FIDO2 authenticator to be listed, created, removed, and customised. Please note that not all FIDO2 authenticators support biometric enrollment. For a description of the types involved, please refer to fido_bio_info_new(3), fido_bio_enroll_new(3), and fido_bio_template(3).

The fido_bio_dev_get_info() function populates info with sensor information from dev.

The fido_bio_dev_enroll_begin() function initiates a biometric enrollment on dev, instructing the authenticator to wait timeout_ms milliseconds. On success, template and enroll will be populated with the newly created template's information and enrollment status, respectively.

The fido_bio_dev_enroll_continue() function continues an ongoing enrollment on dev, instructing the authenticator to wait timeout_ms milliseconds. On success, enroll will be updated to reflect the status of the biometric enrollment.

The fido_bio_dev_enroll_cancel() function cancels an ongoing enrollment on dev.

The fido_bio_dev_enroll_remove() function removes template from dev.

The fido_bio_dev_get_template_array() function populates template_array with the templates currently enrolled on dev.

The fido_bio_dev_set_template_name() function sets the friendly name of template on dev.

The error codes returned by fido_bio_dev_get_info(), fido_bio_dev_enroll_begin(), fido_bio_dev_enroll_continue(), fido_bio_dev_enroll_cancel(), fido_bio_dev_enroll_remove(), fido_bio_dev_get_template_array(), and fido_bio_dev_set_template_name() are defined in <fido/err.h>. On success, FIDO_OK is returned.
