eAadhaar PDF Password
Upon download an eAadhaar arrives as a password-protected PDF document and remains inaccessible until the correct password is entered. This is a deliberate security measure by design. Given that the file contains the holder’s name address photograph and Aadhaar number UIDAI implements this protection to safeguard the document in circumstances such as access via a borrowed device or accidental storage in an unsecured location.
It is important to note that this password is not user-selected and cannot be modified. UIDAI generates it automatically based on the holder’s own personal details following a fixed and consistent rule. Once this rule is understood the file may be opened without difficulty with identical results applying to every subsequent download.

The Password Formula
The applicable rule is straightforward: the first four letters of the holder’s name in capital letters followed immediately by the four-digit birth year. The name must correspond exactly to that printed on the Aadhaar document and the year refers exclusively to the four-digit birth year not the complete date of birth.
For example for an individual named Mahesh Kumar born in 1989 the resulting password is MAHE1989. The two most common errors are failure to capitalize the letters and incorrect use of the complete date of birth rather than the year alone. Where both elements are applied correctly the formula functions successfully in the substantial majority of cases.
Procedure for Opening the eAadhaar PDF
Once downloaded the file may be opened within moments.
- Open the downloaded eAadhaar PDF by double-clicking or tapping the file
- When prompted enter the first four letters of the name in capital letters
- Immediately append the four-digit birth year with no space for example: MAHE1989
- Press Enter to unlock and view the document
Where the default application is unable to open the file it is advisable to use a standard PDF reader such as Adobe Acrobat Reader.
Individuals who have not yet downloaded their eAadhaar should first obtain it via the myAadhaar portal.
Troubleshooting: Password Not Functioning
The substantial majority of access failures result from formatting errors rather than file corruption. The following should be reviewed systematically.
The letters must be entered in capitals; lowercase entry will result in failure as the system distinguishes between “same1990” and the correct “SAME1990.” The full date of birth should not be used only the four-digit year is applicable. The name entered must correspond precisely to that printed on the Aadhaar document including any prior name that has since been amended. Where a download has been interrupted the resulting file may be corrupt.
Formatting should be reviewed and corrected first. Where access issues persist downloading a fresh copy over a stable internet connection and using an alternative PDF reader is recommended.
Troubleshooting: Names Containing Special Characters
Short names initials and punctuation present particular complexity within the formula and UIDAI’s official examples should be regarded as authoritative in such cases.
Where the name is shorter than four letters the complete name should be used in combination with the birth year. For example “Ria” born in 1990 produces the password RIA1990 comprising seven characters rather than eight with no additional padding applied.
Where an initial includes a full stop the punctuation mark is counted as a character. For example “P. Kumar” born in 1990 produces P.KU1990.
Where a short first name is followed by a surname character counting continues into the surname. For example “Sai Kumar” produces the initial segment SAIK.
The applicable principle remains constant throughout: the first four characters should be counted exactly as printed inclusive of spaces and punctuation marks.

Frequently Asked Questions (FAQs)
What is the password for the eAadhaar PDF?
The first four letters of the name in capitals followed by the birth year in YYYY format for Mahesh Kumar born in 1989 this is MAHE1989. UIDAI generates this automatically from the holder’s Aadhaar details; the result remains consistent across every download and cannot be configured or altered by the user.
Why is my eAadhaar PDF password not functioning?
In the substantial majority of cases the issue is a formatting error. Verify that the four letters are entered in uppercase that only the birth year (rather than the complete date) has been used and that the spelling corresponds exactly to the Aadhaar document noting that initials and punctuation marks are counted as characters. Where formatting has been verified as correct and access remains unsuccessful the file may be corrupted; downloading a fresh copy and using Adobe Acrobat Reader is recommended.
Does the eAadhaar password incorporate the full name?
No. Only the first four characters of the name as printed on the Aadhaar document are incorporated never the complete name. These four characters may include a space or full stop where the name contains initials. Where the complete name comprises fewer than four letters the full name is used in combination with the birth year which accounts for certain passwords being only seven characters in length.
What is the format of the eAadhaar password?
Four uppercase letters drawn from the name joined without a space to the four-digit birth year for example ARYA1995. The letters are taken from the beginning of the name exactly as printed and the numerical component consists solely of the birth year. This format is determined by UIDAI applies uniformly across India and is not subject to user customization.
Can the eAadhaar be opened without a password?
No. The PDF is intentionally locked and will not open without the correct password. Third-party tools claiming to remove this protection should be avoided as submitting Aadhaar data to unverified platforms presents a significant security risk. Where an unlocked version is required for personal use the document should first be opened using the correct password then re-saved via the PDF reader’s print-to-PDF function.
How many characters does the eAadhaar password contain?
Typically eight four letters plus a four-digit year though this is not universal. Where the name comprises fewer than four letters the resulting password will be shorter; for example “Ria” born in 1990 produces RIA1990 totaling seven characters. The eight-character format should not be assumed as standard and additional characters should never be appended to achieve this count. The name should be counted exactly as printed.
What if the eAadhaar password is forgotten?
There is no password to forget in the conventional sense as it is not a user-selected credential it consistently consists of the first four letters of the name in capitals combined with the birth year. Where access is unsuccessful the issue is most likely attributable to a formatting error rather than a forgotten credential. Capitalization the year and spelling should be reviewed against the Aadhaar document.
Is the eAadhaar password identical for all users?
The underlying formula is universal; the resulting password is not as it is derived from each individual’s own name and birth year. While the rule applies consistently across India the resulting password will differ between individuals. The password also remains constant across repeated downloads of the same individual’s eAadhaar as the underlying details remain unchanged.
