Do you think it would be possible, to create a second real identity (acknowledged by government) by using the real name, but switching some or even just one of the letters with a unicode look-alike character?

lots of people have the same exact name

it is unknown how a person is represented inside "government". social insurance / social security numbers seem to be relevant even though when they were made it was explicitly said they shouldn't be used for authentication, but now they serve as a sort of password only you're supposed to know (except you have to give it to your employer lol, and MLMs and scam jobs exist so make that make sense)

If the name already exists then they will use your birthdate and birth location and will know that you are the same person.

Your name is not your identity.

@Lensflare funny, I kinda think about my electronic services like that. If I would get hacked or whatever, I'm like meh, it's not my identity. I'm also not someone crying for privacy all the time. I just acknowledge nothing. Criminals, even when they smile with two tumbs up in front of a security camera, they still deny. It's a kinda game.

@Lensflare I also live in Germany but was born in a small village in a foreign country. Back then, when I requested a passport, the women behind the desk asked me how to spell the name of the village. I didn't know, so I just came up with a spelling. Now I know a few other people from that village - it's completely differently spelled in their passport.

Also birthday is something nobody can prove. I can come up with a slight variation or pick another one.

I think the trickiest part is to make someone believe that you lost every document and you are not in "the system" yet.
