Hello guys. Could somebody help me. I would like to move Google Authenticator to another phone and keep all informations I have there. How should I do it? Thank you

First deactivate the authentication from your exchange in your current phone,and then install google authenticator in your new phone and activate authenticator there,

What if I will lose my phone?

If you have lose your phone. You can write to the support term of the exchanger involve to deactivate the authenticator for you.

you must disable it first, if you save QR code it will make it easier to do, and if there is any problem you can contact the support to solve it.
good luck

When you enable 2fa on the exchange ,make sure to copy the private key. You can use it to recover your account.

If you haven't saved recovery key of every 2fa you have set in your old phone than you have to deactivated 2fa from every sites and than activate again so that you can get new key to pair on new phone.

There is no way to recover those key from your old phone to use in new phone.

If you save the image of QR CODE or private key of 2FA  then just download google authenticator in New phone and scan QR Code in New phone or enter private key. It can help you recover your account.

Back up all your QR codes or switch to the authy app which will back them up for you. Either of these solutions would work, and I do both. I keep all them backed up in an encrypted 7Z file with a random 32+ character password and use a 2D barcode scanner with QR codes to keep passwords. I also add prefix characters so even if someone finds the QR codes it won't be of much use. A few prefix characters plus a long 32 character password on a QR code and a cheap 2D barcode scanner bought on ebay equals security and lots of mother loving win.

you know every you want to activate 2fa in a site, they give us secret key that include numbers and letters. it is better to save it, save in flashdisk or write it in paper and keep it safely. every you change phone you can put that key in your new 2fa apps

This, I highly recommend moving away from Google Authenticator and switch to Authy.  It uses the same algorithm as Google Auth and so any website that supports it will also support Authy.  With Authy, you can backup your accounts so it's easy to restore if you lose your phone or want to switch.  I also think the interface is better as well. Ditch Google and move to Authy.

If you have new phone, just disable and then enable 2FA again. I keep my QR printed and stored in the safe place to avoid communication with support in case of loosing/breaking/stealing my phone (and for my wife to be able to access my accounts, just in case).

disable the 2FA on that exchanges and then install on the new phone and then re activate the 2FA on the new phone. not a big deal though

 :)If you have new phone, just disable and then enable 2FA again.  :)

I was about to ask this question because when you lose your phone, GA can be a nuisance. So it is advisable to save the QR code prior to losing your phone.

Thats why i have doubts to use google authentication because you can be in a lot of troubles if you loose your phone. 

Make sure to back it up off the device with Titanium backup, or use an app like Authy so you can cloud back it up.

To transfer all information to another phone you must have the secret key which you had to obtain after the connection is two-factor authentication

deactivate the current's exchange authenticator,then install the google authenticator to your new phone and reactive it again,if you lose your phone make sure you have the backup qr code when you activated your exchange authenticator.

we can not move it, if you lose your phone, you need to redo all the 2FA

It would not works perfect bro. You should keep your google authenticator should be changed in the settings for the trading site by adding the two factor authentication to make your wallet secured.
You should have the trading wallet or browser you are using should be from the same phone you are using google authenticator installed in the phone. This is the recommended option for any users.

when installing the key on each site you are given a reinstatement code 1 time which you must write down and, if necessary, enter it on a new device

If you save your private key at first, then you can directly transfer it, and if you don't have a backup, then close the Google verification first, and then re-create one.

First of all deactivate authenticator where ever you have applied its usage. After deactivating then download google authenticator again on the new/other cell phone and again apply google authenticator.

It is way risky to NOT keep a backup of the secret key while adding any account to Google Authenticator. If you lose your phone or if you need to wipe it for some reason, it would be a pain in the ass to recover all your 2FA codes. In most cases you'll need to contact the support on the sites where you enabled 2FA. (Trust me, I've been through this myself!)

To be safe: whenever you enable Google 2FA on any of your accounts, write down the backup key somewhere safe. You can use this key on a new phone in case something happens to your original device.

At first when you use Google authentication, there will be a qr code, if you save good, then no need to worry about these problems, if you don't save, so you can only communicate by disabling 2 fa or exchange to solve the problem.

For this purpose I do print screen of QR code and store it on my flash card. Also you can use special code (also you need to write it in the first time)

first you need to delete google authentication that is now connected to your account, then through the new smartphone can scan the new code.

Thanks to the poster who discussed Authy.. you just saved me crying myself to sleep when my phone died.. I thought it would auto-sync with google for some reason.. yeah.. no.. goodbye google hello Authy.

Deactivate it and Activate it back on your new phone.

The best thing here to do is to take the print out of the bar code at the time of generating the authentication code. You can keep it safe along with where ever you keep the pvt keys of your wallet.

You can used Authy apps! I think! This is best apps for Google Authenticator in mobile and PC!
I used it for all Google Authenticator on exchange!

You should have the QR code that was generated for the authenticator, if you stored it somewhere safe, you could use that to manually add the info on another phone
