What is Aadhaar eSign?
Aadhaar eSign is a secure digital signing method that enables individuals to electronically sign documents without any physical paperwork. Anyone with a valid Aadhaar number and a mobile number or email ID linked to Aadhaar can complete document signing quickly and remotely.
The signing process uses OTP-based authentication, where a one-time password is sent to the signer’s registered mobile number. This OTP verifies the signer’s identity and authorizes the electronic signature, making the document legally valid and tamper-proof.
With Aadhaar eSign, documents can be signed instantly from anywhere, eliminating delays, manual processes, and the need for physical presence.
