Freeze your credit
I don’t know if it’s the same in the EU, but this is the single biggest thing you can do to protect yourself (I mean besides passwords and such). Freezing your credit makes it much hard to open a line of credit under your name like a random store credit card or such. Please try to do this as soon as you can.
Honestly we do that when we ask and no one speaks up. Lovingly called the “scream test” as we wait to see who screams.
