What this article will cover
A full webnotes article on Two-factor authentication (2FA) will cover the SEBI-mandated two-factor authentication framework for trading and demat logins, the permitted factors, and how TOTP, biometric and OTP factors compare, with internal links to neighbouring topics on webnotes.in and a references section pointing to primary sources.
webnotes.in covers Indian capital markets, payments infrastructure and retail investor procedures. Every article is fact-checked against primary sources, principally SEBI circulars and master directions, NPCI specifications and the official support documentation published by the intermediary in question. Revisions are tracked against the SEBI and NPCI rule changes referenced in the article.
