🤔 What is UDIN?
Before jumping into the login steps, let’s understand it in simple words. UDIN is a unique number generated by Chartered Accountants when they certify or sign documents. It’s kind of like a digital stamp of authenticity — so that no one can misuse your signature or fake your reports.
It’s mandatory for most certificates, audit reports, and financial docs since July 1, 2019.

✍️ Why UDIN Login is Important for CAs?
Because every time you issue a certificate or audit report, you’re supposed to generate a UDIN and link it to that doc. Without this, the document can be considered invalid.
So logging in regularly to check status, generate UDINs, or revoke incorrect ones is a must.

Once you’re logged in, you can:
-
Generate new UDIN
