Google Authenticator

then disable and enable it again

just reset now that you know. It's worth it, I have a hidden paper that's probably more important than my private keys right now with each alphanumeric code they give you before you scan the QR code

This....I dumped Google Auth. Just use Authy.

you need a code from the app to disable it.

>excuse me Mr. criminal, do you mind accompanying me to the nearest place with a secure connection so I can disable the 2FA on my crypto exchanges

Just write down all the backup codes
If you didn't do it and you are on Android you can recover the codes from the database file
But I think you need root for that

Ok just want to check I'm not overlooking anything...
Just disabled 2FA on all my exchanges and then reactivated with authy. Wrote down various new authentication keys on paper. Got backups and password for authy.

I should be good now, right?
My phone's a piece of shit. It was scary to think my crypto holdings all depended on something that could die at any moment.

if you didn't write down the codes on paper, you're fucked

He does have the code because he didn't lose his phone yet. He fucked up the first time around by not writing down the backup.

You can usually call and get the 2fa removed anyways.

you must have never heard of WinAuth

Authy or LastPass authenticator

write down your authentication key on every website where you use it

this. stupid smart phone fags.

>the only right post in this thread

OP I ran into this issue with all the 2FA/Google Auth stuff for all these exchanges. DO NOT USE AUTHY, they are known to be exploited. My Google Auth app isn't connected to any google account, only local. Codes scanned into Google Auth are NOT backed up, not even via an iCloud backup.

My technique, when adding a new code, make an image backup of the QR code to scan, and add it into 2 phones or more.

If you don't have 2FA backups (an action plan if you lose your phone), you're literally asking to get JUST'd.

...

also, l have 2 smartphones with authy, if l loose one, l can still login and disable authentification

Exchanges provide you with backups.

Use Authy. You can still get at your 2fa or disable it if you lose/brick your phone.

You're supposed to save the qr code when you get it. Store it encrypted or print it.

If you use any closed or google software when dealing with crypto you deserve to get your coins stolen. If you use smartphone 2fa at least use free implementation such as fdroid.gitlab.io/fdroid-website/packages/net.bierbaumer.otp_authenticator/

Has an issue with google software and uses an android phone?

really? i just moved all my shit to authy.

prob gonna just do this desu.

>If you use smartphone 2fa at least

learn to FUCKING GOOGLE

>The recovery codes are for the google account, not the authenticators i have with each exchange. As far as I'm aware there's no way of getting that back just from my gmail and phone number.

Yeah, but if you were paying attention, each time you activated 2FA on each exchange you were provided a recovery code.

It will only ever show you that code 1 time, if you lost it, you need to turn of 2fa and turn it back on to get the recover code.

Authy is shit retards

Hackers can easily re-direct your 2FA codes if they have your phone number.

Google Authenticator the codes are tied to your ACTUAL device, so either you would have to lose your phone and all of its QR backups you were supposed to write or the hacker would have to have your physical phone in which case he’d probably just shoot you unless you gave your keys

>really? i just moved all my shit to authy.

coinbase forced me to Google auth in july, wouldn't let me use authy anymore.

did that change?

I killed a phone once by dropping it in a lake and got locked out of both Bitfinex and localbitcoins, and I was able to email them and regain access to both accounts. No I didn't have the backup code.

Just broke my phone and I used Google authenticator. there's no way to restore the codes without resetting then through the exchange unless you too s screenshot of the qr

You can literally save the image to your computer.

for binance they gave me a code that i could put in if i ever lose my authorization. you should copy and paste that and save it if anything happens

Switch off 2FA on all your accounts and then switch it back on this time saving the QR backups.

You can reset those codes and back them up. Just disable and re-enable 2fa and it gives you new codes.

If I uninstall google auth and reinstall it will it give me a new secret key? I lost the paper i wrote it on a while back before i got into crypto

pls

make your phone rooted, install a backup software, then create an image of your phone data, simple
