Securiry Upgraded to Level 2 with Gmail

I have two active mailing account, one from ymail and the other is from gmail. My top priority mail is gmail. I like their ways in securing the user's privacy. Just last week I've upgraded the security of my account to level 2 to make it more secured. Every time I signed in to gmail, it sends a verification code to my phone. Although I feel that it is time consuming sometimes, I'm still with it because it is one way of securing it. And in case you don't have your phone, you can generate some codes that you can use. I'm also happy because I've generated some code and just this morning the network of my phone is not working good. I used the generated code and had successfully logged in at gmail. Don't you want to upgrade it? It will make your mails more secure. Anyone here upgraded their security to level 2? What can you say about it?
