Fun fact: when my country transitioned to a new public authentication app, the default way was to use your passport to register. My passport was expired, though, so I had to show up in person with my birth certificate and social security card equivalent.

To get my birth certificate, I had to show up at the local office with, you guessed it, my passport.

Lucky for me that they accepted it in spite of being expired (none of the pertinent information such as my face, name and birth date had expired, after all), or I would probably be trapped in the loop to this day, years later.
