So today I tried to install Mac OS X Mountain Lion on my mid 2010 MacBook Pro and I have wiped the drive and made a bootable install DVD and booted off it and got through the Reinstall process up until the part where you have to enter your Apple ID. I got past 2FA but now when I enter my Apple ID, it just says “signing into App Store” and then just does nothing.
Earlier Mac models
When you next get to the OS X 10.8 password prompt for the Apple ID, append the two-factor verification code received onto the password input. If your Apple ID password is ABCDEF and the two-factor code is 123456, then enter ABCDEF123456 as the password for the Apple ID.

Installing Mountain Lion:
A. Use Ethernet:
Using a hardware connection is usually more reliable than a wireless one. Use this adapter, if you have no Ethernet connection: Apple USB Ethernet Adapter - Apple
B. Use Internet Recovery Mode:
Hold these three keys down upon boot: Option-Command-R

Installing Mountain Lion:
Well, High-Sierra is the farthest your Mac can install to. So, why do you want to install mountain lion, if I may ask?
For reference...
Upgrading the macOS:
Perform an update, and the latest-compatible macOS will install, with all previous versions being skipped. So, here is how to determine what to install.
In depth...
Installing the macOS:
Determining which Update(s) will Install:
I. Verify Compatibility:
A. Start Here: Learn About Compatibility and how to Identify your Specific Mac Model - Apple Support
B. How to Verify:
I Reveal your Model:
What is the Model of your Mac? To find out...
then...
II. Compare the Results:
See if the Model you found is shown here:
III. If Compatible:
Back Up your Mac First: Be certain you Create a Time Machine Backup of your Mac, so that way you can have something to restore your Mac from, should anything go wrong with the reconfiguration.

Provide Apple with your Feedback:
Do your Park: You cannot perform automatic downloads, so recommend this to Apple. Apple wont get back to you directly, but the more feedback they receive on this the more they can know what their customers prefer, and what features to include in macOS versions to come. Apple will know nothing of your optinions, if your don't provide them to them.
