They tell you not to tell anyone your EMŠO... but EMŠO is generated from your date of birth, gender, former yugoslav republic you were born in (slovenia=50) and the sequental number of your birth that day (0-499 boys, 500-999 girls)... plus a checksum. So if you were born in slovenia, are a boy, and were a third boy born on 20th december 1970 (970... because why waste numbers?!?!), your emšo would be 201297050003K (K=checksum, too lazy to calculate).
We also have a tax number, that they also tell you not to share... but then you open up an independent contractor business (technically, it's a not a seprate company, but "you" are the company), and your personal tax number is published in many many online systems, info pages, you have to put it on receipts, ads, you have to tell it when you're buying toilet paper for work use, etc.
But yeah... if you want to open a bank account, you need a government issued id card (or passport), and they check it very very throughly.
Tax number NIP is relatively public, any relevant accountant will have it.
The remaining secret thing is indeed the ID card and/or the passport. That's why if it ever gets lost or stolen you're supposed to immediately file for a replacement. Theoretically at that point someone might impersonate you.
I recommend contacting the credit rating agencies and getting them to place a note on your record with a password, eg. [1]. Don't wait until someone "steals your identity". It's the only way to get these companies to do something resembling an actual identity check. Doing it after they've lent in your name (as the rating agencies suggest) rather defeats the object.

In countries where this doesn’t exist, obtaining credit requires providing proof of income (payslip, etc) to the lender which they verify. A mere name/address/date of birth might be enough to open inconsequential accounts such as loyalty cards, but will absolutely not get you credit - therefore the damage to identity theft victims is greatly reduced or even nullified.
Bad payers are still penalised even without a credit bureau system by a register the government operates onto which a debtor is registered for a certain period after legal action by a lender (so this requires significant effort from the lender - you don’t get on this register because of a telecoms billing mishap for example).
With regards to setting a password, I wouldn’t trust CRAs to enforce this. What you can do however is pay for CIFAS protective registration - it’s usually for victims or those at high risk of identity theft but there’s no legal requirement so anyone can pay the admin fee and get added to the register. Lenders check this during credit applications and this puts an instant block on any kind of automated approval and requires them to do further verification.
That only works because of low friction lending.
Why not share, if it's so harmless? Isn't that the point you're trying to make?
