Recently, UIDAI has issued an advisory asking people not to share their Aadhaar number openly in the public domain especially on Social Media or other public platforms. Does this mean that I should not use Aadhaar freely?

You should use your Aadhaar without any hesitation for proving your identity and doing transactions, just like you use your bank account number, PAN card, debit card, credit card, etc., wherever required. What UIDAI has advised is that Aadhaar card should be freely used for proving identity and doing transactions, but should not be put on public platforms like Twitter, Facebook, etc. People give their debit card or credit card details or cheque (which has bank account number) when they purchase goods, or pay school fee, water, electricity, telephone and other utility bills, etc. Similarly, you can freely use your Aadhaar to establish your identity as and when required without any fear. While using Aadhaar, you should do the same level of due diligence as you do in case of other ID cards – not more, not less.
