Question Locked device

Hello
I bought a used Mi 11 with locked bootloader. The owner of this Mi 11 has forgotten the Passwort from his Mi Account. So we cant unlock it with the Mi Tool. Is there a opportunity to unlock the device? Or perhaps to flash the reinstall the Rom and erase all user data?
Thanks

If he has only "forgotten" his password and if you are always in contact both, there a option for retrieve/reset actual password like all customer account.
But if you can't log/connect your Mi 11 with a legit Mi account there any way to unlock your bootloader.
Don't wipe your device also because at the first boot Xiaomi asking Mi account for using / unlock the device (linked account)
The seller has no data from the Mi Account for me. In this case,theres is no way to unlock the bootloader?

It's not the question, data or not data, you must log Mi account with the owner Mi account linked to this device.
Xiaomi want a proof you are the owner, device is not stealed.
So ask him to reset the password
Like @Pho3nX said if the previous owner had a mi account it is very easy to change password or phone number associated to the phone, you just need to go to the web browser and reset your account password, they will send you a temporary code to the phone number associated to the phone. If you dont have the number you can associate another number and reset the password. If the device of legit and not Stolen it should work just fine, I have changed my mi account password in the past having my device locked after getting rid of some stock apps, but it is very easy to recover that password.
