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.

Thanks for reply. So basically Google won't backup the authenticator applications? is there no option?

I believe it does. (if i understand you question correctly) You should have received some kind of seed when you setted up your 2FA, which you can type in as a 1 time of recovery.
As i've linked you earlier this explains it, https://support.coinbase.com/customer/portal/articles/2817262

Also, even if you've lost everything, even your seed, i believe that in the case of coinbase, you can still submit a selfie / video session, and they could manually unlock the 2FA for you..

Probably they showed some code when i was setting up. But I didn't take any copy etc because I usually just scan the qr code. Since i started 2FA for other applications as well, I am just thinking what will happen if phone gets lost..
