I have lost the password for my setup. I set it up a few years ago and now I cannot recall it. The supervisor password is not stored in an EEPROM so the usual tricks do not work. I think it is in a TPM chip. Would it be possible to reprogram the chip or replace it to remove the password?
I understand I might lose some key in the TPM that is required to decrypt the data on my hard-drive but that is not a problem. I don't have a boot password and still access my data on the hard-drive and can make a backup copy of it before proceeding with resetting the TPM chip.
