Which keys can be used for the password so that they will be accepted by the Pre-Boot-Authentication?
The PBA (Pre-Boot-Authentication) checks the “scan-code” from the keyboard and not the actual pressed characters, numbers or symbols mapped marked on the keyboard because no keyboard drivers are loaded in the Pre-Boot phase. This means that the key combination “Alt Gr + q” (on a German keyboard layout) needed for the “@” symbol, is not accepted by the PBA and it will issue a false login exception, even though the password was typed in correctly.
The following keys can be generally be used for a correct password.
Please note that the PBA may use a different keyboard layout than your operating system.
The keyboard layout is always the standard layout of the language of your operating system.
So, if you type in a password such as “system” on an English operating system with a German keyboard layout, you have to type in “szstem” in the PBA to login correctly.
A detailed description can be found in the Sophos SafeGuard Disk Encryption manual (Chapter 15.3.1 - The effects of different keyboard layouts)
