Re: Confused identification with authentication.
"For that you need a valid ID which is a choice of Eu biometric ID or passport (which has biometrics). Rest if Europe (except UK which continues with "utility bill idiocy") is the same."
In the UK, you need a utility bill or something similar to establish your address, and a photographic piece of identification (passport or driving licence) to establish your identity. I'm glad my passport doesn't have my address on it, or otherwise it would be even more costly to move when a student. Driving licences do have your address on them, so they can form the second piece of ID, but you still need two.
