Unlock bootloader without Xiaomi MI account?

[grksiswn]

Hi how can I unlock the bootloader without MI account (Xiaomi ID)?

So an offline possibility I'm looking for, because when Xiaomi shut down their central server there is no way to unlock the bootloader afterwards, because the MI account (Xiaomi ID) can only be created with data connection and phone number.

Unlock only with on-line tools , You must. Xiaomi servers are not off-line, i think.
