When you don’t want to handle the creator’s credentials at all, start a mobile attempt. The creator approves the login on their own phone, and you receive the connected account when they’re done. 
curl -X POST https://api.onlyfanskit.dev/v1/connect/login \
  -H "Authorization: Bearer $OFK_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "auth_type": "mobile_app", "label": "creator" }'
Returns 202 with phone_url and auth_code. Share phone_url with the creator (or render the auth_code as a QR). The attempt parks on awaiting_mobile_session until they approve, then resolves to completed_success. 
{
  "attempt_id": "att_...",
  "state": "awaiting_mobile_session",
  "phone_url": "https://api.onlyfanskit.dev/v1/connect/login/att_.../phone?token=...",
  "embed_url": "https://api.onlyfanskit.dev/v1/connect/login/att_.../embed?token=..."
}
Poll GET /v1/connect/login/{attemptId} the same way as email/password login.

Embeddable sessions

For an in-product flow, create a client session and embed the hosted page in a popup or iframe: 
curl -X POST https://api.onlyfanskit.dev/v1/connect/client-sessions \
  -H "Authorization: Bearer $OFK_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "display_name": "Connect your account", "client_reference_id": "user_42" }'
The response includes an embed_url you can open with the onlyfanskit/browser helper (startOnlyFansAuth()) for a native popup, plus a phone_url to share directly. See Embedded connect.
