Description

BSE discontinues the RTRMS direct link and mandates access via the new MemberSSO (Cymmetri) portal. This circular provides a user manual for brokers, banks, and mutual funds to onboard and use the new Single Sign-On system.

Summary

BSE is discontinuing the RTRMS direct link and mandating that all members (brokers, banks, and mutual funds) access BSE applications exclusively through the new Member Single Sign-On (SSO) portal powered by Cymmetri, available at https://membersso.bseindia.com/. This circular serves as the official user manual for onboarding and operating within the new portal.

Key Points

  • The new MemberSSO portal (Cymmetri) replaces the old Member SSO with enhanced features including a new interface, self-service password reset, multiple authentication modes, and self-unlock capability.
  • Access URL: https://membersso.bseindia.com/
  • Three modes of multi-factor authentication are supported: Cymmetri Authenticator app, SMS Authenticator, and Secret Questions.
  • Each member has one Member ID but can create multiple sub-users from the main/admin account.
  • After 3 incorrect password attempts, the user account is locked automatically.
  • Sub-users can request access to specific applications with defined access periods (start/end date or lifetime access).
  • Application access requests require approval from the Main Member before being granted.

Regulatory Changes

  • The RTRMS direct link is being discontinued; members must transition to MemberSSO for all BSE application access.
  • All member entities (brokers, banks, mutual funds) are required to onboard to the Cymmetri-based SSO portal.

Compliance Requirements

  • All members must register and log in via https://membersso.bseindia.com/ to access BSE applications.
  • Members must set up at least one mode of multi-factor authentication: Cymmetri Authenticator (requires downloading “Cymmetri Verify” from Play Store/App Store), SMS OTP, or Secret Questions.
  • When creating sub-users, the UserType field must be set to “Sub_User” exactly — incorrect UserType will prevent sub-user creation.
  • Sub-users must request application access through the portal and await Main Member approval.

Important Dates

  • Effective from the date of this circular (2026-03-06): RTRMS direct link is discontinued and MemberSSO access is mandatory.

Impact Assessment

  • Operational Impact (High): All brokers, banks, and mutual funds must migrate to the new portal to retain access to BSE member applications. Failure to onboard will result in loss of access.
  • Security Impact (Positive): The new system introduces stronger multi-factor authentication, self-service account management, and granular sub-user access controls, improving overall security posture.
  • Administrative Impact: Firms must reconfigure user access, create sub-users under the new system, and train staff on the new authentication workflows.
  • No direct market trading or listing impact, but operational disruption is possible during the transition period if members delay onboarding.

Impact Justification

Mandatory migration from RTRMS direct link to MemberSSO affects all brokers, banks, and mutual funds accessing BSE systems. Non-compliance will result in loss of access to BSE member applications.
