About this app

Authy brings the future of strong authentication to the convenience of your Android device.

The Authy app generates secure 2 step verification tokens on your device. It helps 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 Android device, this way you can authenticate securely even when in airplane mode.

- All of your accounts:
We support most 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.

- What is two factor authentication?
"Two-factor authentication is one of the best things you can do to make sure your accounts don't get hacked" - LifeHacker

Great app when it worked, but I have the same issue with the backup password. Keeps saying that my backup password is incorrect, even though I am 100% certain that it is correct. Even if I reset backup pass, works on other devices but not android. ALSO there is NO WAY TO EXPORT the accounts to another app. That is just wrong, anticompetitive practices. Cant use authy due to bugs, but can't export because they want to lock you in.

For years it was a great app. I used it along side of the desktop app. But authy chose to destroy the functionality that brought a whole section of their user base and remove the functionality that brought me here to begin with. I would have paid for it if the problem was money. They went from having an app on every device and daily use to let's just remove them all together. They had vision and lost it. Bye Twilio.. thanks for some good years. Hate that you lost your way..

It's functional... That's about it. The app does support syncing across devices, including Windows, which is really the only major reason to recommend it at this point. The interface is clunky and awkward. There's no ability to sort your accounts in any way, and entries sort differently on different devices. Additionally, there is no ability to import or export your token information. Overall, it feels like this app is just languishing with no real updates or new features in years.

What's new

The Authy app can now, server side, dynamically increase the amount of rounds of password-based key derivation function for encrypting seeds, making passwords harder to brute force. This allows the app to adapt to the ever increasing compute power. We are leveraging this new feature to make passwords 100 times more resistant to brute force attacks.
