Antifraud, finally pleasant.
Self-service password reset isn't available yet. Your tenant administrator can reset your password from the Team page.
When asking for a reset, share the email address you sign in with so the admin can find your account quickly. They'll either set a new password directly or send you an invite link.
If you ARE the tenant administrator and you've locked yourself out, contact your platform operator (the team that gave you this portal) — they can reset your account from the control center.
