TPM is usually a security chip that holds various keys, passwords, hashes and similar data. One such example, is Bitdifender uses a TPM to store its harddrive encryption keys.

If your laptop has such a chip, you can disable it from the BIOS.

many thanks @KernelOops I'll check bios but strangely boot proceeds with no failure !
So, whats the use of such a key if the door remains open ???

because the TPM is not supposed to block the boot process. Its just a storage area for secret keys and passwords.

UEFI Secure Boot is used for blocking the boot process if signature verification fails.

Thanks, I followed the link...

"You are now ready to get ownership of your TPM module and start the fun 🙂
In future articles we’ll see how we can use it and also how we can program it…"

TPM active, but i still don't see the needs...
This machine used to be corporate i guess, i bought it & changed ssd, added ram & changed os !
I tried quite a number of distros and i get this warning for the first time !!!
yet now i know this exists !
i thought keys & passwords where stored ... somewhere, safely i guess, xept root psswrd
So, it can be done locally...
I'll dig for more info !
