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.

Replaced Google Authenticator

Killer features: [1] Encrypted backup for recovery or new devices. [2] Authorize or de-authorize devices from any other device in case a device is lost or stolen. [3] Optional PIN setting to get into app. and wait for it… [4] Apple Watch app that is FAST! For me this is huge, I don’t have to be digging out my iPhone all the time.

Brilliant combination of features, I have replaced Google Authenticator.

Notes: Do set a PIN for the app in case someone gets your device. Once you have backed up a device, any subsequent devices that are authorized automatically get tokens downloaded from the backup so you don’t have to re-enter them. I was concerned about backup on their servers until I read their description of the encryption scheme; everything done on your device, they don’t get the keys.

Great app but still to be improved

I've been using Authy for a long time and really enjoy using it as a replacement for Google Authenticator. I've been gradually moving all my tokens, nearly 100 of them, from Google Authenticator to Authy. But for a perfect app, there are still things for Authy to do. Sometimes the sync process becomes weird and clients on different platforms/machines may have different records for a single token, which could last several months and may even result in broken records. The other thing I can barely bear, is that long urls may cause problems, both in displaying and renaming. There's a limit on the length of the url one can input on some platform, but not on the others, but none of them display correctly or completely in some other platforms. Looking forward to more improvement.

Best 2-Factor

I got a new phone and restored from an Apple Backup. All my Google Authenticator codes were gone. GONE! Good thing I had another device to authenticate with or I would be screwed.

Switched to Authy to avoid this problem in the future. Seems to be working and the app is 100x nicer than others I've seen and used...
