I have tried it by Personal number – it is on payroll and on confirmed travell orders, or call Irena. but finally I retrieved it through my email addres.

Click here (do not “open in new tab”)

Here I entered my Muni email… firstly it complained several times something about “address is not in database”, but then it yielded… I don't remember for sure and I don't want to try it because I don't want to block myself… Maybe it showed something about different email address or something…, nevertheless an email arrived promptly and after clicking, a password appeared and I printed it to PDF and saved.
