Request 3PAO assessor access
Submit your work email, accreditor name, and ATO engagement reference. Pyrenth issues a single-use magic link with a 10 minute TTL (NIST 800-63B-4 §3.1.3.2). The link is bound to the originating IP and user agent so a forwarded link cannot mint a session elsewhere.
Pyrenth logs every magic link request, consume, evidence read, and logout for chain of custody under NIST 800-53 AU-2, AU-10, and AU-12. No PHI is exposed in this portal at any step.
