Github personal access token as password

So, as I was working on a project required by an online course I am currently following, I hit quit an interesting problem:  I couldn't push my work to my Github repository. The reason being SourceTree kept asking for the password. 

Reason: Using two factors authentication with Github requires creating a personal token and using it with SourceTree.
