It is not even required to mount your disk from other hardware. Simply 
boot to the grub menu and set this boot parameter:
init=/sbin/sulogin --force

As long as someone has physical access to the Debian carrying disk, you 
can always break into the system! In this case for restoring your access 
options, but of course in other cases this could also be used for evil 
things.
In order to prevent the evil access option you need to activated disk 
encryption. To my knowledge this cannot be bypassed as easily as simply 
gaining root access on an unencrypted system. But of course, if you now 
forget your decryption passphrase, then your system is gone for ever, 
also no more accessible by mounting the disk in another system. If you 
now would have a problem with the root password or sudo setup, you would 
for sure still need the disk decryption passphrase, and only afterwards 
could help yourself with the mentioned boot parameter.
Best wishes, Marco.
