Yes, it is possible to wipe a locked computer using various methods depending on the level of security and the reason why the computer is locked. For instance, if the computer is locked by a password, you can use specialized software or hardware tools to bypass or crack the password and gain access to the computer's files and folders. However, if the computer is locked due to encryption or security features such as BitLocker, FileVault, or Secure Boot, wiping it may require some additional steps and technical knowledge. Moreover, it is important to note that wiping a locked computer may result in data loss, and therefore, it is recommended to consult with a professional before proceeding.
