Register your research.
PDD is a consented panel: people who have chosen to share their own data. This is your account, and it asks for very little. Your institution, your protocol, your IRB approval and your signatory belong to a STUDY, not to a login, so they are collected when you create one. Participants are never paid, and no payment method is needed at any point.
Your PIN safeguards your Lab and study rooms. You enter it to open your workspace.
Confirm your address.
A 6-digit code was sent to . Entering it confirms the address is yours. It is the same verification every account on PDD clears.
You're registered.
Keep the recovery code somewhere safe. It is the only way back into the account if the password is lost; we cannot recover it for you.
Next: create your first study. That is where your institution, your approved protocol, your IRB approval and your signatory are collected, and where the participant PIN is generated. You distribute that PIN to your recruited cohort; they enter it to join, so no one outside your roster reaches your study.
