Why is a ProxKey USB Token Used?

With India’s growing emphasis on secure digital transformation—particularly in taxation, MCA filings, and government tenders—ProxKey helps maintain data integrity and identity verification. Here’s why it’s essential:

Security: ProxKey ensures the digital signature cannot be exported, copied, or tampered with. It’s secured with encryption and a user-defined PIN.

Legal Validity: As per the Information Technology Act, 2000, digital signatures stored in a certified token like ProxKey are legally valid in India.

Portability: Being USB-based, ProxKey is easy to carry and can be used on any compatible system—perfect for professionals on the move.

Required for Online Services:
ProxKey is accepted across major Indian portals like MCA21, Income Tax e-Filing, GST, EPFO, DGFT, and eTendering platforms, which all require DSCs stored in secure tokens.

How Does a ProxKey USB Token Work?

The ProxKey acts as a secure storage and signing device for your digital certificate. Here’s how it works:

Get Your DSC Issued: First, apply for a Digital Signature Certificate from a licensed Certifying Authority in India.

Token Initialization: Your DSC is installed into the ProxKey token using the official Watchdata software. A secure PIN is created during setup.

Using the Token:

1. Plug the ProxKey into your computer’s USB port
2. Enter your PIN when prompted
3. Select your certificate
4. Sign or authenticate as required
   The private key used for signing never leaves the token, ensuring complete security. Only the document hash is processed within the device.

Compatibility with Applications:

ProxKey works seamlessly with:

• MCA (Ministry of Corporate Affairs)
• Income Tax Portal
• GST Portal
• DGFT
• EPFO
• eTendering (GeM, eProcurement, etc.)

It supports Windows, Linux, and macOS, with proper driver installation.
