OAuth hosted login: verify the emailed MFA code

POST/oauth/mfa/email-otp/verify

Step 2 of the hosted email-OTP MFA factor: verifies the emailed code against the challenge_token. On success it optionally issues a trusted-device cookie, mints an authorization code, and redirects to redirect_uri; on failure it re-renders the challenge page in the "code sent" state with the error. Throttled to 10 requests per minute.

Request body

application/json

challenge_tokenstring Required
client_idstring Required
redirect_uristring Required
response_typestring Required
scopestring Required
statestring Optional
code_challengestring Required
code_challenge_methodstring Required
noncestring Optional
codestring Required

The one-time code received via email.

remember_deviceboolean Optional

Remember this browser so the next hosted sign-in from it skips the second factor. Honoured only when the Environment's `mfa_trusted_device_days` is above 0 (the default is 0, which disables remembering); the trust rides in the httpOnly `ca_identity_mfa_trusted_device` cookie on Canopy's domain.
