This article provides basic instructions to help users bypass the Pre-Boot Authentication in case they forgot their password. The Pre-Boot Authentication provides multiple ways for users to authenticate to gain access to their computer in the events like this. It is recommended to be off the network when performing the recoveries described below.

The first and easiest way for users to authenticate to Pre-Boot Authentication after forgetting their password is by using Question and Answers authentication. The first time a user logs in to a computer, they are prompted to answer questions configured by policy. After providing answers to these questions, they will be prompted for their answers. Assuming they have answered the questions correctly, Pre-Boot Authentication allows access to the Operating System.

To get to the Recovery Questions dialog in Pre-Boot Authentication, follow the steps below:

Note: A valid username and domain must be provided before clicking the Recovery Questions menu option.
  1. Enter a valid username and domain name and then select Options > Trouble signing in > Recovery Questions.
    Recovery questions
  2. When the Recovery Questions dialog appears, enter the answers for the questions that were enrolled at first login and click Submit.
    Answers for questions
  3. Once the authentication is successfully completed, the endpoint boots in the Operating System.

Challenge Response can be used to authenticate through Pre-Boot Authentication and boot into Windows. Challenge Response can be used in the following scenarios:

  • In the event a user does not remember the answers that they supplied at the time of enrollment.
  • Recovery Questions authentication is not enabled.
  • A user is remote with no network connectivity and cannot receive an unlock command from the Security Server using Pre-Boot Authentication Device Controls.

A user can get to the Challenge Response screen by clicking the Options > Trouble Signing in > Challenge Response menu options or entering their password incorrectly X number of times without the network cable plugged in.

Note: A valid username and domain must be provided before clicking the Trouble Signing in menu option.
  1. Enter a valid username and domain name and then select Options > Trouble Signing in > Challenge Response.

  5. Enter the Device Code that the user provided into the Challenge field and click Generate Response.
  6. Provide the user with the generated Response Code. These codes are not case-sensitive. The numbers are shown in red and the letters in blue.

  7. The user enters the Response Code into the Response Code field in Pre-Boot Authentication.
  8. Click the Submit button to continue and authenticate passed Pre-Boot Authentication.
    Submit
  9. Once the authentication is successfully completed, you should see the message below.
    Authentication successful
    Note:
    • Challenge Response only allows you to authenticate passed Pre-Boot Authentication one time. Once the machine is shut down and restarted, the machine resumes protection, and the user have to authenticate passed Pre-Boot Authentication again.
    • Once a user has been sent to the Challenge Response dialog, the user must complete the Challenge Response to gain access to the computer. If they shutoff the machine and attempt to log back in - even with the correct password - Pre-Boot Authentication prompts again with the Challenge Response dialog.
