Twilio Authy Authenticator

Authy

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.

Ratings and reviews

New UI is meh. I really hate the size of the text and would like it to be customizable; I'd like to be able to shrink the text size a bit, a lot of my accounts get cut off because they don't fit and if I have multiple accounts under one company (like I do for Microsoft for work), I can no longer quickly distinguish which token is for which account. Also, dark mode only covering the bottom half of the screen while the top is light is clinically insane.

Authy has a critical, long-standing bug. When restoring encrypted tokens, the app decrypts a random number: sometimes nearly all, sometimes 75, sometimes only one. The same correct backup password is then rejected for the rest. I changed the password many times—same issue on all devices. This is totally unacceptable. These are sensitive credentials, and if you cannot reliably decrypt them, the app becomes worthless. Please address it urgently.

The app has been very reliable and useful, in particular it's ability to be used on multiple devices including a PC. Then Twillio decided it was a good idea to mess it all up with a UI "update". Not just a subtle change here and there, no, the entire thing was rebuilt from the ground up. It's a horrendous UX now, and a good example of "don't try to fix something that isn't broken". Thankfully a certain password manager now supports keeping MFA, so off I go. Thanks for all the fish!
