Google Authenticator or Authy

[silvermint]

I'm using both but I found that I can use Google Auth on a lot of websites compared to Authy. Might have to remove my Authy because of the security risk that I've only just read now in this thread (obvs, I didn't do a lot of researching about Authy) lol!

Would you guys recommend Duo better than G Auth? Or that's a different thread?

I've just found this thread whilst researching Authy/Google Authenticator for something totally different, but it looks like I should be applying it to my Bitcoin account too.

Based on the information in (and linked from) this thread, I think I'll go down the Google Authenticator route. So far I've picked up that I will need to keep a paper backup of the recovery code, but are there any other tips?

Google Authenticator has been very good to me so far in my experience. I have not used Authy so I can't compare. If you do use Google, make sure you back it up! I had to reset my phone and I forgot to back my Authenticator up and it was alot of work to reaccess most of my accounts. Besides that, it's a great app.

But in that case what do you recover with the backup codes? All the websites you had with the 2FA? Or only Google's?

Because shortly I'm gonna change my phone (keeping my phone number) and I'm still trying to figure out how to move all the exchanges 2FA I have in GA

You really need to back them up as you create them. Before scanning each QR code into Authenticator I take a screenshot of the QR code and print a couple of copies, keeping one at home and one off site. Then it is just a case of rescanning them when changing device.

I would definitely recommend Google Authenticator. Now, less but I used it a lot before and I'm happy with it. In my opinion this is a very useful thing.

I use Google Authenticator and have never had any problems. The codes are generated every 30 seconds and you don’t need to use internet or cellular connectivity to receive the code. This is key as i've found that often using text messages for authentication is hit or miss. I would often not receive the codes.

Why would anyone use Google Authenticator if they don't let you backup your codes? Why not use a open source 2FA app like AndOTP or a cheap paid one like Authenticator Plus?

Lost your device and haven't saved your codes before enabling 2FA? Bye bye accounts.

I use google authenticator and really like it! You have to have my phone with you to login to my accounts. It is very easy to use as well. You just scan a barcode and are good to go.

I prefer Google authenticator as it can be trusted. But it won't allow to backup code.

[Alluro]

Google Authenticator is best with security.

[Frank9]

For me Google Auth is the best.

[EricaRinehart]

When you first set it up they give you a list of backup codes to print out so no issues there as long as you don't loose the printout.

For private use I use Google Authenticator and so far I have not had any problems. The codes change every 30 seconds.
The company for which I work use Authy and for access to corporate services Authy has proven to be reliable.
I think both services are ok.

[Ale88]

Does Authy work offline as well? And is it linked in any way to the phone number?

If you want to use it on an iPhone I can recommend HDE OTP:

Google authenticator is the 2fa I use and it works properly without bugs.

You know, but it’s really interesting to watch how cryptocurrency is becoming more available for each of us. https://mytc.io/ Ive just checked their website and wanna try it. A blockchain platform to turn time into the cryptocurrency.
