I am using two factor authorization to login many btc/ltc trading sites with google authenticator android app.
I logged into my gmail account in google authenticator app.

Question-1) I only have google authenticator installed in my one android phone. If I lost my cellphone how can I login to those trading sites? Will I be able to login with another cellphone using my google account in the google authenticator app?

Question-2) I dont login to my gmail account with two factor authorization. but if I do it later for security, then if I lost my cellphone then how can I login to my gmail account?

In the Gmail account security setting you also have mobile phone authentication, you can have more than 1 phone numbers. If you lost your phone, then just recover your password using the mobile phone authentication. Then you have access to it again.
