The pricing examples on this page, including the “Cost for 10K Users” comparison row, are snapshots based on publicly available pricing pages for TryMellon, Clerk, and Auth0 as of March 2026. They are meant to illustrate the shape of costs for a typical B2B team evaluating passwordless auth vendors, not as a contractual quote for any provider. Each vendor may change prices, tiers, or discounts at any time, and your actual bill will depend on usage, region, and any custom agreements you sign. For TryMellon, the Starter, Growth, Scale, and Enterprise tiers described here are the default SaaS plans; the dashboard and docs always contain the most current details and should be treated as the source of truth.
