BIOS Password

All Microsoft Surface units include a default BIOS password. For increased security, you should change this password during initial setup. For units that you deploy in your venues, we require that you change this password. For additional security, you should change the BIOS password again in the future, after the initial BIOS password change.

The BIOS password can be up to eight (8) characters long and is not case-sensitive. We recommend that your BIOS password follows strong password conventions, such as:

  • Do not base the password on any user account name or easily discoverable personal, corporate, or venue information.

  • Use at least six characters from the following categories:

    • Alphabet letters

    • Arabic numerals (0-9)

    • Nonalphanumeric characters (for example, !, $, #, %)

Also, make sure that you avoid using any common manufacturer BIOS backdoor passwords. You might want search for these common passwords on the Internet before you select a new BIOS password.

To change the BIOS password, you will need to know the current password. To obtain the default BIOS password for your Microsoft Surface unit, contact Microsoft Surface Customer Support.

You must connect a USB wired keyboard or wireless keyboard to the Microsoft Surface unit before you change the BIOS password. You cannot complete this procedure remotely.
