Exactly what details do you have of your target?

E-mail (its gmail ofc) and I have the correct password, but it always asks me to verify via sms. It blocks out the number, and I've tried everything I can to find the raw phone number, but I can't. The user isn't active in many places so its not in any databases, and I tried googling everything I could on him but nothing shows up. So just the e-mail and the password, and the common username he uses everywhere (which isn't much).

It's a bonus the target has setup 2FA via the "Text message (SMS)" option, and not through voice call. First and foremost, you must obtain the cell phone number. I realize you've exhausted all options, but It does exist somewhere. Once that's done, you will SE your victim to get the 2FA verification code as follows:

• Spoof your caller ID, then send an SMS to the target as though you're a Google representative. In the text message, write something along the lines of "We're performing a routine annual security upgrade, you will receive a verification code shortly".
  

• Wait a few minutes and then generate the verification code via the account holder's "Account recovery".
  

• Your target will receive the verification code on their phone- on the assumption It's been legitimately generated by Google.
  

• Shoot off another text (within a minute) with a message of "To finalize the security upgrade on your account, please reply with the code. Thank you- Google staff".
  

• You'll  receive have the 2FA verification code.
  

• Sign In thereafter.
  

Note: It's very Important to establish your target's timezone. Perform the above on a weekday during the evening hours, and not on the weekend (they may be out and about) and certainly not during the time they're asleep.
