Two Factor Authorization Question.

[taher]

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?

Back up your Google Authenticator keys somewhere safe: on paper or maybe in a TrueCrypt file.

I'm wondering the same thing, is it the end of the world if you lose your phone?

Not if you've backed up your keys!

How do you back up your keys?   I had the same worry, man it's scary using authenticator without having a backup but I don't know how to do it!

Sites with Google Authenticator enabled offer you the key in QR and text format when you activate the 2FA. Retrieve that key, probably from the site's Security section, and note it down on paper or in a text file within a TrueCrypt.

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.
