Question

When trying to enter my password at PBA level, I always receive the message "login failed". Is this related to the keyboard layout?

Answer

At the time of PBA logon, no Windows drivers are loaded, which means that at this point no special keyboard layout is loaded. An exception to this rule can be read further down in this article.

In order to be keyboard independent, Sophos SafeGuard Disk Encryption (SDE) uses scan codes. So, it remembers that your password consists of "second row, third key from the left, third row, first key, ..." and so on.

Additionally, SDE is aware of roughly a dozen keyboard layouts. It will, during installation, check which keyboard settings are defined under Windows and keep this information for the PBA logon.


Example: the French keyboard has the letter A where an English keyboard would have the letter Q.

In order to allow the entry of a username such as "Andre", SDE has to support the French keyboard layout as well.

On one hand, at PBA level, no Windows keyboard drivers are loaded. On the other hand, it should be possible to enter a username such as "Andre". So, at this stage, it is a bit of a combination of both.

The keyboard layouts included are very much representative of the countries in which we have subsidiaries (eg. US, UK, Norway, Sweden, Belgium, France etc.).

A Hebrew keyboard layout, for example, is not included with SDE.

So, in this case, at PBA level, Sophos SafeGuard Disk Encryption will default to US keyboard layout.
