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.

Great app a must have

This is a 100% must have app to secure all your online account from Gmail to Facebook and loads more.
I would like to see more icons for example I use this app with some mmo gaming website like runscape and they is no icons for that you have to use the one that are provided would be nice to have more options.

I would recommend this app to all thou one of the best feature of this authy is that it backs up all your codes to they cloud and is 100% secure. This means that if you get a new iPhone your codes are they whating.

The authenticator to rule them all!

This is hands down the best way of using 2 step verification for any service. The main downside to using other apps is that they have no backup so when you get a new device or reset your device you lose all of your accounts.

Authy has a desktop app too which is a game changer for my work machine and means I don’t even need to pick up my phone.

Great app!

Really useful but really primitive

Lacks a lot of customisation. Looks and feels like a school project, ie seriously no-frills. Account icons are tiny so the caption text gets truncated and you can’t distinguish between them. Why can’t we have a list view? Why no fields for notes or custom icons? (I have a dozen Google accounts each of which look identical within Authy). Phone number field is wrong, i.e. there’s no logic for correctly formatting numbers outside the US. Interface howlers include if you protect the app with a PIN, you have to tap ‘Cancel’ to finish which suggests it will undo your changes. Battery use insane: is routinely responsible for 30% or more of my phone’s power drain. Could go on.
