The password for e-Aadhaar is a combination of the first 4 letters of your name in CAPITAL letters and the year of birth (YYYY) . For example, if your name is Suresh Kumar and your year of birth is 1990, then your password will be SURE1990. If your name has less than 4 letters, then you should enter your name in full and add "0" at the end to make it 4 letters long. For example, if your name is Ria and your year of birth is 1990, then your password will be RIA1990. The password is meant to provide utmost protection to this important document and ensure security so that no one can use it for fraudulent activities.
