Some questions about the gruB2 password

[address@hidden]

Hi,
I am having some problems with grub2 password security in Linux.

1.Currently, when setting a GRUB2 password, the password strength is not 
verified. Weak passwords such as 123456 can also be set into the GRUB 
configuration file
2.The previous password is not verified when setting the password

This may involve some security risks; is there any way to make my GRUB password 
more secure?
