Supplemental Guidance

Issuing authenticators in person or by a trusted external party enhances and reinforces the trustworthiness of the identity proofing process.

Practitioner Notes

This enhancement requires in-person or trusted external party involvement when issuing authenticators — someone trusted must physically verify the recipient's identity.

Example 1: Require new employees to receive their initial password and MFA token in person from the IT help desk after the HR department confirms their identity.

Example 2: For remote employees, use a bonded courier service to deliver hardware tokens and initial credentials, with signature verification upon delivery.
