Hosted sign-in pricing compared
Most hosted auth providers charge per monthly active user, and often put passkeys or an extra sign-in step on a paid tier. CorroborateMe is hosted sign-in for apps and AI agents at $5.99 a month or $55 a year, with no per-user pricing.
How hosted auth is usually priced
Most hosted auth providers meter the people who sign in during a month. A free allowance is common, and past that allowance the bill is usually a base fee plus a per-user rate. Passkeys, or a second step such as multi-factor sign-in, are often reserved for a paid tier. Access for scripts and other machines is sometimes a separate meter or an add-on. Those prices and caps change by vendor, so this page does not quote them.

What moving looks like
CorroborateMe is not a drop-in replacement for another provider's SDK. Moving an app means calling different endpoints. This product does not publish an uptime SLA, and it does not offer inbound SAML or phone sign-in. The migration guide lists the CorroborateMe calls, and pricing shows the live amounts.
Questions

No. The hosted sign-in, API keys, login-link JSON, and OIDC client registration are CorroborateMe's own API. You do not point another provider's SDK at this host.
Is CorroborateMe priced per monthly active user?
No. There is one paid plan, Pro. It is not priced by monthly active user. An agent can prepay the same flat amount for 30 days. See the pricing page for the current amounts.
