Complete Guide to UIDAI Password Requirements 2025

Introduction

The Unique Identification Authority of India (UIDAI) issues the digital version of the Aadhaar card—the e-Aadhaar PDF—and enforces password rules to protect highly sensitive identity data. While the rules look simple, the security and compliance implications are significant. This guide covers what you must know in 2025. Try our free tool at www.passwordchecker.in.

What Is the Password Rule?

When you download your e-Aadhaar PDF (via the myAadhaar portal or the mAadhaar app), the file is password-protected. The password format is: first four letters of your name (in uppercase) + your birth year (YYYY).

Example: If your name is “Sameer Sarkar” and your year of birth is 1990, the password is SAME1990.

Why This Format, And Is It Sufficient?

Security rationale:

• Provides a minimal barrier so an unauthorised person cannot open your file easily.
• Balances memorability with basic privacy across millions of users.

Limitations:

• Predictable: anyone who knows your name and birth year can guess it.
• Fixed pattern: users cannot customise or change it.
• Effectiveness depends on exact name spelling as printed on Aadhaar.

Implications For Compliance And Users

For Individuals

• Ensure the Aadhaar name spelling is exact; the first four characters must match precisely.
• If your name has fewer than four letters, use the full name followed by the year of birth (e.g., OM2000).
• Do not share the e-Aadhaar password. It protects the PDF only, not the backend UIDAI systems.
• Use passwordchecker.in to check your password strength before storing or sharing the file.

For Organisations

• Verify password-rule compliance when collecting e-Aadhaar files from customers or employees.
• Do not bypass PDF protection in automated pipelines; maintain chain of custody.
• Supplement with access controls, encryption at rest, audit logging, and least-privilege.

Outlook And Recent Updates (2025)

The e-Aadhaar PDF password scheme remains unchanged. Broader UIDAI and government updates continue to strengthen authentication standards and data governance. Treat the fixed PDF password as one control in a layered security model that includes OTP, device hygiene, and access governance.

Conclusion

The rule—first four uppercase letters of your name plus your birth year—is easy to apply, but predictable. Use it correctly, then add stronger practices around storage, sharing, and access control. Test your password now at www.passwordchecker.in.
