Download emSigner & emBridge for MCA – Install, Activate and Register DSC
The MCA portal requires a DSC signing utility to be installed on your computer before you can attach a Digital Signature Certificate (DSC) to any eForm. The utility required depends on which portal you are filing on:
| Portal | Utility required |
|---|---|
| MCA V3 (current) | emBridge by eMudhra |
| MCA V2 (old, now largely retired) | emSigner |
If you are filing on MCA V3 — which covers all current Company and LLP filings — you need emBridge, not emSigner.
Install emBridge for MCA V3 (Current Method)
Download and install emBridge from eMudhra’s official website.
Once installed, open the MCA V3 portal and log in.
Go to MCA Services → DSC Services → Associate DSC.
Click on Associate DSC — emBridge will launch automatically in the background.
On the pop-up, select the correct Token and Certificate, enter your Token Password, and click Register.
Your DSC is now associated with your MCA V3 account.
