AWS EC2 Linux - GRUB with password
Any idea if it is possible to set password for the GRUB bootloader? If set then how it is possible to enter password? What happen when auto scale without human entering password?
AWS does not provide "console access" to EC2 instances, so you can set a GRUB password the usual way, but you will not be able to enter it at boot. Your instance will become inaccessible after reboot.
If you absolutely need GRUB password (but why?) the only option is to look at other providers that allow use console (DigitalOcean, for example).
