disable bios unlock/reset after setting a password

I found some easy methods to unlock/reset bios password if you forgot it. like type the wrong password 3 times and then you get some number and enter it in a web page, which generates a password to log in with.

is there a way to prevent that? I want to lock bios and stop other users for sure not getting in to make any changes. that could be dangerous if they get into bios make boot from USB or sth...

does anyone have a suggestion on how to secure bios/boot?

2Short answer, no you cannot prevent bios being unlocked by known tricks, buy a laptop that does not have one of those weaknesses. – Moab – 2019-09-20T13:36:36.080

Through the BIOS menu, you can set and change an Administrator password, sometimes called also Supervisor password.

By setting an Administrator password, you will prevent other users from changing your BIOS settings, as this password will be needed to enter the BIOS.

The Administrator password is different from the BIOS password, since it is not required for booting the computer, only for modifying the BIOS.

Warning: Never set the two BIOS passwords, Administrator and User, to be the same. You risk to never again be able to modify the BIOS.

1There is no defense against a knowledgeable user that has physical access to the computer and can boot it. Taking out the hard disk is the only sure defense. – harrymc – 2019-09-21T18:24:11.700
