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.

Loads better than Google's Authenticator

I set Google's Authenticator up on all of my accounts... But, one day, I forgot my phone at a friends house. So, I was, effectively, locked out of all my Google, Hotmail, and ETC stuff. With this app, I can have more than 1 phone for all the accounts. It makes it so much easier. Especially since it auto syncs everything and is encrypted.

Best 2-factor app, hands down

Between Authy's proprietary service and their ability to do Google Authenticator codes, Authy does it better than the rest. I love the fact that it syncs between my phone and tablet, so if I have one or the other I can still access my accounts. And with the ability to add a pin, your 2FA is protected in the event that your phone or tablet is stolen.

a reliable app for 2FA, I've used it for years

A reliable, stable app for 2FA. I prefer it to Google Authenticator or other offerings.

Works with where you might use Authenticator AND with extended 2FA for apps whose developers who use Authy (Twilio) APIs for longer codes.

Great support for syncing across devices if you choose to do so. And if you choose to trust them with backups of your 2FA setups, that is possible, too.
