Check a certificate.
Type the number on the certificate or scan its QR code. In a second you see whether it is genuine.
What this check shows
Only what is needed to know the certificate is genuine: the number, the name, the course and its topics, the date it was issued, the partly hidden SMSF auditor number (SAN) if the holder gave one, and whether it is valid.
It never shows the test score, study time, email, payment details or anything else. A cancelled certificate (for example, after a refund) shows as not valid. It is a certificate of completion from a private company. It does not show approval by ASIC or the ATO, because their rules set a test and do not list courses.
