Why Your Aadhaar PDF Is Password Protected — And How to Open It
You downloaded your e-Aadhaar from the UIDAI website. A PDF appeared in your downloads folder. You tapped it and got hit with a password prompt you didn't expect. The password isn't random, it isn't complicated, and you don't need to call anyone to get it. This guide tells you exactly what it is, why it's there, every special case explained with examples, and what to do when it still doesn't work.
The first time this happened to me, I genuinely spent about ten minutes searching for "e-Aadhaar password" — reading through vague answers that all said the same unhelpful thing: "it's based on your personal details." Which personal details? In what format? What if your name has multiple parts? What about initials?
The answer turns out to be very simple and completely predictable. UIDAI specifies it exactly on their official FAQ page. But finding that page and understanding the edge cases takes longer than it should, so a lot of people end up staring at the wrong guesses and wondering whether they've somehow corrupted the file or need to download it again.
This guide gives you the exact formula first — before anything else — and then explains everything else: why the password exists, what happens with unusual names, how to open the file on each device type, and a specific troubleshooting checklist for when the correct password still somehow doesn't work. Over 1.3 billion Aadhaar numbers have been issued across India as of 2026. This problem affects essentially everyone who downloads their e-Aadhaar online, and the answer is simpler than the confusion around it suggests.
The Password — Right at the Top, No Scrolling Needed
Here is the exact formula, directly as specified in UIDAI's official FAQ:
- Name: RAKESH KUMAR · Born: 1990 RAKE1990
- Name: PRIYA NAIR · Born: 2001 PRIY2001
- Name: P. KUMAR · Born: 1990 P.KU1990
- Name: RIA · Born: 1990 RIA1990
- Name: AMIT · Born: 1984 AMIT1984
- Name: A S RAMA · Born: 1995 ASRA1995
The name used is exactly as it appears on your Aadhaar card — not your common name, not your nickname, not the name on your PAN card if it differs. Your Aadhaar card name. The year is your birth year in four-digit format — 1990, not 90. And every letter must be uppercase — the password field is case-sensitive, so typing rake1990 instead of RAKE1990 will fail.
Why UIDAI Password-Protects the Aadhaar PDF at All
Your e-Aadhaar is not just a document — it's a legally valid identity proof under the Aadhaar Act 2016, accepted by banks, insurance companies, government offices, telecom providers, and practically every KYC process in India. It contains your full name, date of birth, residential address, photograph, 12-digit Aadhaar number, and a QR code linking to UIDAI's verification system.
That's a lot of sensitive personal information sitting in a PDF file that can be downloaded online, shared over WhatsApp, emailed as an attachment, or accidentally forwarded. Without a password, anyone who received or found the file could open it immediately. The password ensures that even if the file ends up somewhere it shouldn't — in the wrong inbox, on a shared computer, forwarded accidentally — the person who has it still can't open it without knowing your name and year of birth.
It's a practical security layer rather than a cryptographic one. The password itself is deterministic and personal — you'll never forget it because it's derived from information you know by heart. UIDAI's own guidance describes this as an intentional design: easy enough that you'll always be able to derive it yourself, but still a barrier to casual unauthorised access.
📜 e-Aadhaar Is Legally Valid — The Password Doesn't Change That
A password-protected e-Aadhaar downloaded from UIDAI's official portal is legally equivalent to your physical Aadhaar card under the Aadhaar Act 2016. Banks, airports, government departments, and KYC processes must accept it. The password protection is a security feature, not a limitation on its validity. Once you open it with the correct password, the document you see is fully authentic and legally usable for any purpose where Aadhaar is accepted as identity proof.
Special Cases: Short Names, Initials, Single-Word Names
The "first four letters" rule works cleanly for common names like Rakesh, Priya, Sunita. It gets more interesting for names that are shorter than four letters, names with initials, or single-word names — which are common in South India and among many communities across the country. UIDAI has specified how each of these works.
If your name is shorter than four letters
Use all the letters you have. If your name on Aadhaar is SAI and you were born in 1995, your password is SAI1995 — three letters, not four. If your name is OM and you were born in 1988, your password is OM1988. UIDAI confirmed this directly: for a name like RIA born in 1990, the password is RIA1990. You don't need to pad it with anything.
If your name includes initials (like P. Kumar or A. S. Ramaiah)
This is the case that trips people up most often. UIDAI's official example is clear: for P. KUMAR born in 1990, the password is P.KU1990. The initial, including the period/dot after it, is included exactly as it appears in the name. For a name like A. S. RAMA, the first four characters of the name are A. S. — but since UIDAI's example for "A S RAMA" uses ASRA1995 (skipping spaces), this is where some variation exists depending on how the name was enrolled.
If your name has spaces in the initials part and the P.KU-style password doesn't work, try removing the spaces and using only alphabetical characters from the first portion of your name. If neither works, re-download and try both variations — the section on troubleshooting below covers this specifically.
Single-word names (common in Tamil Nadu, Telangana, Kerala, and others)
If your name on Aadhaar is a single name with no surname — KARTHIK, VENKATESH, LAKSHMI — the first four letters of that single name form the prefix. KARTHIK born in 1992 → KART1992. VENKATESH born in 1985 → VENK1985. LAKSHMI born in 2000 → LAKS2000.
| Name on Aadhaar | Birth Year | Password | Note |
|---|---|---|---|
| RAHUL SHARMA | 1993 | RAHU1993 | Standard two-word name |
| PRIYA NAIR | 2001 | PRIY2001 | Standard two-word name |
| P. KUMAR | 1990 | P.KU1990 | Initial with dot included |
| A S RAMA | 1995 | ASRA1995 | Spaces skipped in initials |
| RIA | 1990 | RIA1990 | Name under 4 letters — use all |
| SAI | 1995 | SAI1995 | 3-letter name — use all 3 |
| VENKATESH | 1985 | VENK1985 | Single-word name |
| MARY JOSEPH THOMAS | 1988 | MARY1988 | Only first word used |

The password is correct — that part you can trust because UIDAI's formula is fixed and published on their official website. When it still doesn't work, the cause is almost always one of these specific things.
| What Went Wrong | What It Looks Like | How to Fix It |
|---|---|---|
| Lowercase letters | Typed "rake1990" instead of "RAKE1990" | Turn on Caps Lock before typing the name portion |
| Autocorrect interference | Phone changed "RAKE" to "Rake" automatically | Type in a notes app first to confirm, then copy-paste into password field |
| Wrong name used | Used PAN card name or common name instead of Aadhaar name | Check a physical Aadhaar card or previous download for exact name as enrolled |
| Name spelling difference | Name enrolled as "POOJA" but you typed "PUJA" | UIDAI spelling is the one that matters — check your actual Aadhaar card |
| Wrong year format | Typed "90" or "1990s" instead of "1990" | Always use exactly 4-digit year: 1990, 2001, 2005 |
| Initials handling | Not sure whether to include dot with initial | Try both P.KU1990 and PKU1990 — one will work depending on enrollment |
| Corrupted download | Password correct but file still errors | Delete the file, re-download fresh from uidai.gov.in, try password again |
| Incompatible PDF reader | Some browsers' built-in PDF viewers struggle with UIDAI's encryption | Download Adobe Acrobat Reader (free) and open with that specifically |
The autocorrect problem on mobile
Someone I know spent twenty minutes trying to open their Aadhaar PDF on their phone, convinced the password formula was wrong. They were typing correctly — first four letters of name, then birth year — but their phone's keyboard was changing the first letter to title case and keeping the rest lowercase. So they were entering "Mano1988" instead of "MANO1988". The phone wasn't showing them what it was doing clearly because the password field masked the characters.
The fix was simple: open Notes on the phone, type the password there to see what they were actually typing, confirm it was all uppercase, then copy it and paste it into the PDF password field. Opened immediately. If you're on mobile and nothing is working, always check what your keyboard is actually typing rather than what you think you're typing.
✓ Type in Notes first, then copy-paste into the password fieldHow to Download Your e-Aadhaar If You Haven't Yet
For anyone who hasn't downloaded their e-Aadhaar before, here's the process from UIDAI's official portal. You'll need your registered mobile number (the one linked to your Aadhaar) nearby because an OTP will be sent to it.
- Go to uidai.gov.in — UIDAI's official website. Look for "My Aadhaar" in the navigation and click "Download Aadhaar" under the Get Aadhaar section.
- Enter your Aadhaar number — the 12-digit number printed on your physical card. You can also use your Enrolment ID or Virtual ID if you prefer not to enter your full Aadhaar number.
- Complete the captcha — type the characters shown in the image and click "Send OTP."
- Enter the OTP — a 6-digit OTP is sent to your registered mobile number. Enter it on the page. At this step you can choose whether you want a regular Aadhaar (full number visible) or a Masked Aadhaar (only last 4 digits shown). More on this choice in the next section.
- Click "Verify and Download" — the PDF downloads to your device. This is the password-protected file you now know how to open.
⚠️ Mobile Number Not Registered With UIDAI?
If your mobile number isn't linked to your Aadhaar, you won't receive the OTP and the online download won't work. In this case, visit the nearest Aadhaar Seva Kendra (ASK) with valid ID proof. They can provide a printout for ₹30 (colour print) or a PVC card for ₹50 after biometric verification. To link your mobile number for future online access, you'll need to visit an Aadhaar enrollment centre — this can't be done entirely online.
Masked Aadhaar: What It Is and When to Use It Instead
When you download your e-Aadhaar, UIDAI gives you a choice: regular e-Aadhaar or Masked Aadhaar. Most people either pick whichever is pre-selected or choose the regular one without thinking about it. The masked version is actually worth understanding because for a significant number of everyday situations, it's the smarter choice.
A Masked Aadhaar shows only the last four digits of your 12-digit Aadhaar number. The first eight digits appear as XXXX-XXXX instead of the actual numbers. All other details — name, photo, address, date of birth, and the verification QR code — remain fully visible. The document is completely valid for identity verification.
The reason to prefer it: your full 12-digit Aadhaar number is more sensitive than most people treat it. While knowing only your Aadhaar number isn't enough on its own to impersonate you (authentication requires your biometrics or OTP), unnecessarily exposing it everywhere does create a data trail. For routine situations — showing Aadhaar at a hotel check-in, submitting for a gym membership, providing for address verification — the masked version confirms your identity equally well while giving out slightly less information. UIDAI themselves recommend it for basic KYC where full number exposure isn't necessary.
✅ When to Use Regular vs Masked Aadhaar
- Regular e-Aadhaar: Bank account opening, income tax filings, passport application, government schemes requiring full Aadhaar number, formal KYC processes at financial institutions
- Masked Aadhaar: Hotel check-ins, address verification for deliveries or memberships, anywhere you're asked for "Aadhaar as identity proof" without a specific need for the full number, everyday casual verification
Frequently Asked Questions
No. The password is set by UIDAI and is built into the document at the time of generation. It cannot be changed, removed, or personalised by the user. This is intentional — the fixed, deterministic password format means you can always derive it yourself without needing to remember a separately chosen password. Every e-Aadhaar PDF you download from UIDAI will always use the same formula: first four letters of your name in capitals plus birth year. The only way to get a PDF without this password would be from an unofficial or tampered source, which you should treat as suspicious.
Always use the name exactly as printed on your Aadhaar card — not your PAN card name, not your passport name, not what your family calls you. UIDAI's system uses the name enrolled in their database, which is what appears on the Aadhaar card itself. If your Aadhaar says "RAJU" but your PAN says "RAJESH", the password uses "RAJU" (or "RAJU" plus the year). If you're unsure of the exact spelling on your Aadhaar, look at a physical card or a previous successful e-Aadhaar download. If you've never had a physical card and this is your first download, the name you enrolled with during Aadhaar registration is what UIDAI has on file.
After a name update on Aadhaar, the password for any newly downloaded e-Aadhaar will use the updated name. If you download a fresh e-Aadhaar after a name change, try the new name's first four letters with your birth year. Old PDFs downloaded before the update would have used the old name — but since you'd typically download a new one after updating to reflect the change, this usually resolves naturally. If you're in the period immediately after a name update and the download is reflecting the new name but you're uncertain, try both the old name's password and the new name's password.
Yes. A printed e-Aadhaar is legally valid as identity and address proof under the Aadhaar Act 2016. Open the PDF with your password, then print it using any standard printer — black and white is acceptable, though colour is clearer. The printed document is accepted by banks, government offices, courts, hotels, insurance companies, and all other entities that accept Aadhaar. The key thing is that it must be printed from the official UIDAI download, not a photocopy of someone else's card or a modified version. The QR code on the printed Aadhaar can be scanned for instant verification of authenticity.
It's best avoided, but if necessary, take precautions. On a shared computer: open the PDF, use it for what you need, then delete the downloaded file from the downloads folder before leaving. Also clear the browser's download history and temporary files. The bigger risk with shared computers isn't the PDF password being seen — it's the file itself being left behind where others can access it or the browser autosaving your UIDAI session details. If you need to access Aadhaar on the go, the mAadhaar app on your own phone is a safer option since it keeps the document within the app environment rather than as a loose file accessible on any device.
The e-Aadhaar PDF from UIDAI is already relatively compact — typically under 1MB. However, some older portals and email attachments have very low size limits, and you may occasionally need to reduce it further. The complication is that because the PDF is password-protected, most standard PDF compressors can't process it without the password being entered first. You'd need to open it with the password in a PDF editor, save an unlocked version temporarily, compress that, and then use the compressed version. For a privacy-preserving approach, a browser-based PDF compressor that works locally — like the PDF tools at 21k.tools — processes the file on your device without sending it to any server. Open the PDF, apply the password, compress, and download the result.
The Short Version for Bookmark Purposes
Your e-Aadhaar PDF password is: first 4 letters of your name exactly as on Aadhaar, in CAPITALS, followed by your 4-digit birth year. SURESH VERMA born 1991 → SURE1991. RIA born 1990 → RIA1990. P. KUMAR born 1990 → P.KU1990. That's the full formula, directly from UIDAI's official FAQ.
If it's not working: check that every letter is uppercase, that you're using your Aadhaar name not another ID's name, that the year is four digits, and that your phone's autocorrect hasn't silently lowercased anything. When all else fails, re-download the PDF fresh from uidai.gov.in and try again — a fresh download clears most file-level issues.
And once you have it open — if you need to compress it for an upload portal or email, the free PDF tools at 21k.tools process locally in your browser. Your Aadhaar PDF never leaves your device during the process.
