Windows 10: Windows 10 Pro BitLocker GUI not accepting 256-character passwords

When I boot my PC and try to unlock my BitLocker-encrypted D: drive by double-clicking it in Windows Explorer, copying & pasting my 256-character decryption password into the graphical input field does not work. The exact same password works fine when I runmanage-bde -unlock D: -passwordfrom the command line, so it's definitely a GUI issue. I'm not sure if this is the right place to ask, but is it possible someone could please file a bug report about this? This is my Windows install information:Edition Windows 10 Pro Version 22H2 Installed on ‎8/‎20/‎2020 OS build 19045.4529 Experience Win

Bitlocker password 256 characters breaks unlocking


I'm not sure I fully understand, as the link you provided already contains the answer?

So, even if you used 256 characters for the main password, is there a reason you can't use the 48 character Bitlocker recovery key (which is different to the main password) to recover the drive?

You can find a tutorial regarding using the Bitlocker recover key to unlock a drive at the following link:

Bitlocker password 256 characters breaks unlocking


Hello
I've run into a little problem with bitlocker password length. Somewhere I read that you can use up to 256 characters for the recovery password so I generated such a password via keepass. The bitlocker UI obviously had no problem with this. After restarting the system and trying to reenter the password i get the message "the password entered is incorrect".
According to this article BitLocker Passwords Should Be Less Than 100 Characters in Length - TechNet Articles - United States (English) - TechNet Wiki
passwords will be truncated to 100 characters. I already tried reducing the password to 100 chars without any success.
To reproduce this problem I enclose the used password here
Code:

Anybody have any ideas on how to unlock the drive with this password?

 

Bitlocker password 256 characters breaks unlocking


Well the op made several errors. Not storing the recovery key is one but it started earlier. Who the .... uses a 256 digits password? I would not expect any program out there accepting such a password. Security is a good thing and long and random passwords are a necessity but 256 digits? Come on, a little bit exaggerated isn't it? Even 20 or so digits are uncrackable in reasonable time with today's processing power.
