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 ???

RHEL supports TPM 2.0 since 7.6

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 !
