Solution : Google Authenticator continuously crashes

This happened to me when i moved from one phone to other. on investigation i understood that google only allows one authentication device. as on the old phone this setup was already done, The only easy option is to move the authentication to a different phone.

Following is the few step process that worked for me.

1. Open Authenticator but do NOT press the “Begin setup” button.
2. Instead, select “setup account” from the option menu.
3. Then from another device/computer, go to https://accounts.google.com/b/0/SmsAuthSettings, select “Move to a different phone” and scan the QR code.
