Hello friends,

I have recently enabled 2 factor authentication using google authenticator for different exchanges such as coinbase, kraken and some more applications.

My question is, what happens if my phone breaks or get lost? In my new phone if i install google authenticator with same phone number, will it automatically get backed up?

if not, what option will I have if phone is lost or broken?

Thanks

You should have received a backup code in the form of a QR-code, or a seed, see

I'm using coinbase here as an example, as im imagining Kraken & Bittrex will all be very similar to this.

Hello can i ask if is it possible to use 2 device with the same account? I just planning to make a back up to my second phone

Yes. Though you need the backup code in any case. Either you set the 2FA entry up at the same time, so you scan the QR-Code on both devices or enter the backup code manually, or you need a backup of the backup code to set it up later on the second device.

Okay i got it, will try now and i saved my back up code. Thank you for your replied i really appreciate.
