Start at /partners/recover. Three routes, in order of speed:
Upload the resume you applied with. We compare it against the document on your candidate record. A strong match is strong evidence you are who you say you are.
Answer questions about your application history — which roles you applied to, when you first applied. Only the real account holder knows these.
Open a support ticket. The last rung, for cases the first two cannot settle. Describe the situation and a person reviews it.
All three land in the same review queue. Reviews take 24–48 hours and the decision arrives by email. If approved, you get a link that lets you set a new password.
Password resets are deliberately not instant-by-email-alone for this program, because a partner account controls where money is sent.
The partner help centre covers attribution, the ledger, payouts and the selling rules.
