Is new Password System Secure? 

Now it works with 2-step verification, while before the latest update it wasn’t 
like that, and i think that old one was more secure. Can you please assure that
Its secure than old one?

P.S: i think the old one was secure because it was accepting “Gmail App Password” 
that was working one time.so thats why i think it was secure.

Hello, if you’re thinking about the OAuth option for securely signing in to your Gmail account, yes this option is more secure than it’s predecessor.
We’ve implemented this feature because the previous option for signing in was shutdown by Google, you can read more about the new feature on our blog…
