For security reasons, vaults cannot continue to be accessible anonymously. This is not being done only "to please Warmasters".
You do not need an account if you are not going to access the vault.
I do not understand this measure unless you're hiding an incident from the participants, has anything happened that requires reinforced security measures and that you won't tell us?
Also, I'm allowed to play, but if I don't behave like everyone else and sign up to a spying, information selling provider, I will be degraded to a second-rate participant?
