Cloud Authenticator:2FA | Pass

The Cloud Authenticator generates 2-Step Verification codes on your phone. 
Cloud Authenticator can also be used to secure your other online accounts that support TOTP or HMAC one-time passwords.
Two-step verification provides stronger security for your online account by requiring a second verification step when you sign in. In addition to your password, you'll also need a code generated by the Cloud Authenticator app on your phone.
Secure Cloud Backups:
Did you lose your device and get locked out of all of your accounts? Cloud Authenticator provides secure cloud-encrypted backups so you will never lose access to your tokens again. We use the same algorithm that banks and the NSA use to protect their information.
Multi-Device Synchronization:
Are you re-scanning all your QR codes just to add them to your tablet and smartphone? With Cloud Authenticator, 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? This way, Cloud Authenticator generates secure tokens offline from the safety of your iOS device. This way, you can authenticate securely even when in aeroplane mode.
All of your accounts: 
We support most major multifactor authentication accounts, including Facebook, Dropbox, Amazon, Gmail, and thousands of other providers. We also support 8-digit tokens.

Cloud Authenticator is the preferred two-factor authentication solution to protect your bitcoin wallet. We are the default 2FA provider for trusted companies like Coinbase, BitGo, and many others.
Additionally, we will request access to use your camera for the sole purpose of scanning QR codes when activating accounts. Accounts can be activated by other methods if you choose not to do so.
