Learn How to Use eSign for Secure Digital Signatures via Aadhaar OTP
Share this article:
The Government of India has enabled a fast and secure way to sign documents online using a method called eSign , which works in conjunction with Aadhaar OTP verification. This digital facility has transformed the way we sign agreements, applications, and official papers by making the entire process paperless, contactless, and time-saving. Whether you are submitting a tax document, applying for a government scheme, or signing a legal agreement, eSign is a trusted tool accepted by various organisations and portals.
This article explains what eSign is, how it works, and how you can use it with your Aadhaar OTP to sign documents digitally.
The process uses Aadhaar-based eKYC (Know Your Customer) authentication. Once the user enters their Aadhaar number and receives a one-time password (OTP) on their registered mobile number, that OTP is used to verify the individual’s identity. After verification, a digital signature certificate is generated and used to sign the document electronically.
The platform or portal you are using must support the eSign feature
The document must be in a supported digital format such as PDF
Once these conditions are fulfilled, you can proceed to digitally sign the document in just a few simple steps.
Step 1: Visit a platform that supports eSign, such as DigiLocker, eMudhra, or NSDL eSign.
Step 2: Upload the document you want to sign or select an available document within the portal.
Step 3: Choose the ‘eSign’ or ‘Sign using Aadhaar’ option.
Step 4: Enter your 12-digit Aadhaar number and click on ‘Get OTP’.
Step 5: You will receive a one-time password on your registered mobile number.
Step 6: Enter the OTP to verify your identity.
Step 7: Once the OTP is validated, your document will be digitally signed with a legally valid digital signature.
Step 8: Download or share the signed document as needed.
This process typically takes less than two minutes and ensures a secure and legally recognised way of signing.
No need for physical presence or couriering of documents
Legally recognised and compliant with Indian law
Saves time and resources for both individuals and organisations
However, it is important to use eSign only on trusted platforms and avoid sharing Aadhaar or OTP information with unauthorised parties.
eSign using Aadhaar OTP is an efficient, secure, and legally recognised method to sign documents online.
