You forgot the part where they send you two distinct snail mails, one with the username and one with a one-time password, for a double chance the post will lose one of the envelopes! Or the part where they silently truncate your new password to 6 digits because muh security.
I guess France and Germany are siblings in kafkaesque administrative shenanigans.
In Germany if they silently truncate your password and you contact their customer service, they will scream at you for not remembering your password. I guess this beats France.
