That's the government's POV and it's highly contested. I've read some people say it can actually be financed by other means, and some other say that the pension plan isn't even in danger

The pension system is doomed and everyone knows that. But noone wants to do something to prevent it from collapsing because that could result in temporary disadvantages.

The old system of taking the money from the youth and giving it to the older citiziens only worked because there were more working people at the beginning of their worklife than old people who needed this money. The demographic changed some decades ago the way that there will be a lot of old people in 10-15 years but barely any young payers. Transfering money from person A to person B without augmenting it, isn’t sustainable. 

As I said, the pension system which is present in many european countries will only work in the future if the money gets invested and therefore gets more by itself. Raising the pension age will only move the problem a few years into the future
