Understand it
Keep passwords, PINs, OTPs, backup codes and wallet recovery phrases private. Be cautious with full ID numbers, passport or identity-card images, banking documents, signatures and complete birth details. Combined information can help someone impersonate you.
Some verified services need identity or payment information. Check who is asking, why it is needed and how to send only the required details. Do not upload documents through an unsolicited link or publish them to prove your identity in a public comment.
Under the hood
Personal data and authentication secrets have different roles. A name or bank routing detail may be necessary for a legitimate transaction but can still help targeted deception. Data minimization considers the recipient, purpose, channel and retention, rather than marking all fields simply safe or unsafe.
Practitioner perspective
Document collection purpose, minimum fields, access and deletion schedules. Provide secure intake rather than informal chat requests. Assess identity-proofing and account-recovery flows together; public biographical facts are weak secrets. Jurisdiction-specific legal duties require separate review.
