The short answer
The registry records Clerk User Authentication Platform as a possible interpretation of CLERK* AUTH. This descriptor-to-company association has not passed claim-level evidence review. Compare the exact line, amount and posted status with your own receipt or account activity; the name alone cannot confirm the merchant or whether you authorized the payment.

Why it shows up like this
Unreviewed registry note: CLERK* AUTH on your card or bank statement is a monthly subscription charge from Clerk Dev, Inc., the company behind the Clerk User Authentication Platform. Clerk provides ready-made user authentication components — sign-in forms, OAuth social logins, multi-factor authentication, and session management — that developers drop into React, Next.js, and other JavaScript applications. If your company builds or maintains a web application, someone on the engineering team likely integrated Clerk to handle user accounts.
Unreviewed registry note: To find this charge, log in to dashboard.clerk.com and select the relevant application. Go to Settings, then Billing, to see your current plan, active MAU count, and downloadable invoices. To stop future billing, click Manage Plan and downgrade to the Free tier, which supports up to 10,000 MAUs at no cost. If you do not recognize the application or workspace, ask your development or IT team before disputing — this is a common developer tool billed to company cards.
