Complete login with a passkey assertion

POST
/v1/auth/mfa/verify
curl --request POST \
--url https://api.aetherpush.com/v1/auth/mfa/verify \
--header 'Content-Type: application/json' \
--data '{ "pendingToken": "example", "response": {} }'

Verifies the WebAuthn assertion for a pending login and, on success, consumes the pending token and issues the session access key exactly as a non-MFA login would.

MFA satisfied. Use the returned access key as a Bearer token.

Media typeapplication/json
Login
object
accessKey
required

Raw bearer token. Send as Authorization: Bearer <accessKey> on subsequent requests. Store securely (cookie or secure storage). The server cannot reveal it again.

string
expires
required

Unix timestamp in milliseconds at which this token expires.

integer format: int64
mfaSetupRequired

Present and true when the account has no MFA method yet. Every account is expected to enroll a passkey or an authenticator app. The dashboard nags until mfaSetupDeadline and blocks navigation after it. Clients that cannot enroll (the CLI) may ignore this field.

boolean
mfaSetupDeadline

Unix timestamp in milliseconds. Present alongside mfaSetupRequired; fixed on the account’s first MFA-less login and stable on later logins. Before it, MFA setup is a dismissible prompt; after it, the dashboard requires setup before continuing.

integer format: int64

Example

{
"accessKey": "abc123-base64url-secret",
"expires": 1719964800000
}

Malformed request or WebAuthn response.

Media typeapplication/json
Error

Standard error envelope. code is the stable machine identifier for client branching and i18n. The wording of error is a human-readable fallback and is not part of the contract. Specialized responses keep narrower code enums where clients already branch on them.

object
error
required

Human-readable error message.

string
code
required

Stable machine code. Prefer this over matching on error. The values this API can answer with are listed in the ApiErrorCode schema of the raw document at https://api.aetherpush.com/openapi.yaml. The field stays an open string here so that a release adding a value does not invalidate this response.

string
requestId

Unique identifier for the request, also exposed as the X-Request-Id response header.

string

Example

{
"error": "The requested resource was not found.",
"code": "not_found",
"requestId": "req_abc123"
}

The pending login is invalid or expired, the challenge does not match, or the assertion failed verification.

Too many MFA attempts.

RateLimitError

Returned with HTTP 429 when an endpoint-specific rate limit is hit, including the per-tenant management API budget. Not the process-wide address limiter (see GlobalAddressRateLimitErrorResponse). retryAfterSeconds indicates how long the client should wait before retrying, and matches the Retry-After header when that header is set. code names the limit that fired so clients can translate without matching on error.
