forgot login and password

Thanks a lot, and how do I get to the GRUB ?

There is no Grub on SBCs (yet?), hence why tophneal said:

Best bet is to loosely follow the '2. Reset Lost Root Password Using Live CD' set of instructions - basically booting from an image via microSD, mounting your emmc (not /dev/sda1, as that's a hard drive) and then chroot'ing in and resetting the password.
