Yes, this safe can be mounted under a table and the hardware is included.
You cannot set it so it is fingerprint only, nor can you set it so both are required. So the correct answer is any of the three modes can open this and you cannot remove a mode if you are concerned with the fact that the design means there are actually not many possible combination on the key pad, you cant disable the keypad and use only fingerprints.
recommend to be mounted to a horizontal surface, but I purchased a very strong magnet (holds 30 lbs) and cut out the foam padding to accommodate the magnet and it holds the weapon very securely on a wall mounted unit.
It is not difficult.
It will generally hold just one. I have a Glock 17 that fits perfectly in one and a 38 revolver in another.
it is small an expensive to use it as a dedicated storage for ammunition. If you wanted to store a loaded gun or a gun wiht a spare loaded mag, and a box of ammo it iwll fit and will be fine. Generally you don't store much boxed ammunition in a safe. It many jurisdiction it is a code problem to do so. Why? Ammunition stored in ammo boxes is a small hazard in a burning home, it is a major hazard if stored in a sizable safe as you are containerization explosives amplifying any explosion. You can get ammo boxes that have spaces for padlocks. But this safe is small and the amount of ammo you would have in it with your firearm is trivial
It is pretty easy, the batteries is in a holder stored under the buttons.
Not sure how to answer the cable lock question but this safe does come equipped with lag screws so the safe can be permanently affixed. The safe allows for two different sets of fingerprints 4 buttons programmable in any entry sequence (no numbers)
