Start a new game in ME2 and, when the option appears, select Import ME1. You can find that mod on the Nexus website. As long as you have a copy of the original Mass Effect 2 on the same system, though, you can still get hold of a face code.
If you're playing the Legendary Edition, you will need an additional mod in order to access these console commands. There are some Mass Effect 2 console commands that you can use to get things like God Mode and instant access to XP and talent points.
You can reload your save from earlier as many times as you want to gain the most points, but again, it will take a long time to get anywhere! Now you can reload your save and cross the walkway for the next conversation, which gives +4 Paragon points or +4 Renegade points that are persistent across saves. There's a small walkway between two crates where you overloaded the crate earlier, and you'll want to duck behind the crate on the left and save before continuing on. You'll have a conversation with Jacob and Wilson at this point, where selecting the upper right option will give +4 Paragon points while selecting the bottom right option will give +4 Renegade points. All you need to do is play through the mission to the point where you meet Wilson and overload the crates. You can activate a glitch in the mission Prologue - Awakening that gives you an infinite amount of Paragon or Renegade points, but note that it takes a very long time to make it worthwhile since you only get about four (4) points every time you do this.
