Aadhaar eSign is the digital alternative to the traditional pen-based signing process with the same legal validity. The Aadhaar Based eSign process promotes digital literacy and empowers individuals to participate in online activities. With this digital solution, individuals can now sign their documents by using their Aadhaar number and OTP received on their registered mobile number. Aadhaar eSign is widely used for government services like filing income tax returns, applying for passports, and obtaining driving licenses. However, you should check with your partner to avoid any hassles.Â
