Authy brings the future of two-factor authentication to the convenience of your iPhone or iPad.

The Authy app generates secure 2 step verification tokens on your device. It help’s you protect your account from hackers and hijackers by adding an additional layer of security.

Why Authy is the best multi factor authentication app:

- Secure Cloud Backups:
  Did you lose your device and got locked out of all of your accounts? Authy provides secure    cloud encrypted backups so you will never lose access to your tokens again. We use the same algorithm banks and the NSA use to protect their information.

- Multi Device Synchronization:
  Are your re-scanning all your QR codes just to add them to your tablet and smartphone? With authy you can simply add devices to your account and all of your 2fa tokens will automatically synchronize.

- Offline:
  Still waiting for an SMS to arrive? do you travel constantly and lose access to your accounts? Authy generates secure tokens offline from the safety of your device, this way you can authenticate securely even when in airplane mode.

- All of your accounts:
 We support most major multi-factor authentication accounts including Facebook, Dropbox, Amazon, Gmail, and thousands of other providers. We also support 8 digit tokens.

- Protect your bitcoins:
  Authy is the preferred two factor authentication solution to protect your bitcoin wallet. We are the default 2fa provider for trusted companies like Coinbase, CEX.IO, BitGo and many others.

Broken token, BT sync doesn't work

Tried to use this as a replacement for google authenticator. I really liked the idea of Bluetooth sync to have a strong second factor authentication for my desktop from my phone. However, the desktop app wants me to re-register the secret token again, instead of fetching generated codes from the phone via Bluetooth. This completely negates the advantage of second factor authentication.

Additionally the generated tokens do not match those created by Google authenticator (I used the same QR scan for both apps).

Confusing to use, broken app. Don't waste your time like I did.

Crap process for managing account

I loved this app, until I switched my cell phone number. I went through the process to try and switch my account phone number to my new number, but Authy responded telling me if they allowed me to switch my number that it put my account in danger. WTH kind of bass ackward logic is that? If you keep my account locked to my old phone number you directly put my account at risk to misuse and keep it in a vulnerable state. The acknowledgment codes now will only go to someone with my old number, who I don't know. Will NEVER use again. Read a SEC book some time you hacks.

Best 2-Factor app around

This is the best 2-factor app I've used yet. Having backups of the codes is very helpful. This made upgrading my phone super easy, I just registered the new phone with Authy and all of my codes were instantly available without having to go reconfigure all of my tokens! Love it!
