Usually people get a second passport if they have to visit Iran and the US. This is legal in the EU and a somewhat standard workaround.
Work would like me to go to Iraq, which is fine. They’ll pay for me to get a US Visa too.
Trouble is in 20 years time when I want to go to NY for my kids wedding or whatever, I’ll still have to answer “yes” to the “I visited Iraq” question, and I won’t be working for the company that sent me there, so I’d have to go for the long arduous process of prostrating myself at the US embassy to beg for a visa, incurring a large expense to do so. Just because the stamp isn’t in my active passport doesn’t mean I can answer “no” to the question
It’s not like Israel, where the stamp would cause problems but they don’t ask (or the other way round where an Israeli stamp would cause problems going to Iran).
Even when I apply for a visa and have to list every country (often in a comically small box with like 100 characters max length), like with India, it only asks “what could tries have you visited in the last 10 years”
In Portugual you really need a very good reason for a 2nd passport and being convenient for tourism isn't one.
Since then I’ve reduced the number of visa based countries I’ve needed to go to (more have gone electronic), and countries have reduced stamps, throw in covid, and it’s to the point that I doubt I’ll fill my passports up before the 10 years has expired. It’s a shame really, the stamps in past passports are a great momento, but places like Hong Kong, Israel, Canada, Australia have all stopped stamping in the last few years.

It is an exercise in geography to track down down which 16 countries don't care you have an ID card.
Edit: a crime to use it as a “workaround” (i.e. lie) to US customs, that is
Using a second passport, fake passport, alias, fake glasses and moustache doesnt make a differnce to the answer to that question. Its not even a workaround.
