"In order to enhance the security measures, the exchange shall be implementing two-factor authentication (2FA) for users of CBRICS (Corporate Bond Reporting and Integrated Clearing and Settlement platform)," NSE said in a circular.
The two-factor authentication would be implemented from June 28. While the mechanism would be optional till July 5, it would be made mandatory from July 7.
"During the optional period, users can choose to skip 2FA settings by clicking on 'skip to application' tab," it added.
The exchange recently also implemented the facility for users of its electronic bidding platform -- Nse-ebid -- for allocating debt investment limits for foreign portfolio investors.
NSE has also initiated two-factor authentication for users of its web-based e-IPO, mutual fund as well as negotiated trade platforms.
