General Questions
AT.Wallet
1Why do I need a crypto Hardware Wallet?
If you keep your virtual assets on an exchange, you are entrusting your private keys to a third party and authorizing them as security. The cold wallet is unloaded so that hackers have a harder time accessing your stored coins for improved security. The private key is always offline and stores inside SE (Secure Element), all paths are encrypted.
2Coins / Tokens supported by AT.Wallet?
Coins: BTC / BCH / XRP / ETH / LTC/ DOGE / DASH
Tokens: ERC20 Token
3What if I lost my AT.Wallet?
AT.Wallet only allows pairing with authorized devices, and you do not need to remember any pin codes or passwords, AT.Wallet only recognizes your fingerprints. Therefore, in case of theft or loss of your wallet, it is still possible to prevent anyone from logging into your wallet and using it. You may enter your 24-word seed codes to recover your wallet.
4Is the security chip really safe?
The ATWallet is designed with Infineon CC EAL+ Secure Element, a dedicated chip for storing private keys and PINs.
During a transaction or connection to a host device via USB or Bluetooth, the private key is securely stored and protected from possible attacks by hackers.
5Any third party certifications it's not hacked device?
Authentrend will definitely consider seeking certifications, but we don't know of any crypto-specific certifications so far. Non-crypto-specific certifications will not likely test some critical aspects of blockchain security, so customers relying on these 3rd party certifications will have a dubious sense of security. For those who are truly paranoid about security, the best option is to store some funds on many different hardware and software wallets. Even if some are compromised, you will still have the others to rely on.
ATKeys
1What is FIDO?
FIDO (Fast Identity Online) is a set of standards and specifications developed by the FIDO Alliance to provide an alternative solution to traditional password authentication schemes. FIDO security keys are hardware-based security keys that support the FIDO specification to ensure the security of web service accounts.
2What's the difference between FIDO UAF, U2F and FIDO2?
For an overall tutorial of U2F and UAF, please see the below document from FIDO: U2F & UAF Tutorial.
FIDO 2 is comprised of the W3C Web Authentication specification and corresponding Client-to-Authenticator Protocols (CTAP) from the FIDO Alliance. FIDO2 supports passwordless, second-factor and multi-factor user experiences with embedded (or bound) authenticators (such as biometrics or PINs) or external (or roaming) authenticators (such as FIDO Security Keys, mobile devices, wearables, etc.).
3Why should I use FIDO security key?
Traditional password authentication schemes have several security and usability issues. Using simple passwords for multiple sites poses security risks, such as phishing and MITM attacks. Using complex passwords also poses usability issues and frequent password resets.
FIDO Security Key provides a secure authentication solution for online accounts using public-key encryption. The Security Key will create a new set of key pairs to increase security.
4How to passwordless sign in the Azure Active Directory on my PC?
Based on FIDO2 standard, FIDO2 certified security key allows users achieve passwordless authentication with the combination of Azure Active Directory (or office 365 accounts) on your PC and Web services without typing anything.
5What happens if I lose my ATKeys?
Don't worry at all if someone gets your security key, they can't log into your accounts without your fingerprints. And you can still log in to your account by using a backup security key or some other way. If someone tries to use your security key, more than fifteen errors will automatically lock them out.
6How often should I charge my ATKey.Card?
Please keep the battery charged every three to six months to extend the battery's life and avoid damage to the electrochemical system.

5Is the fingerprint encrypted on the device?
The fingerprint is encrypted and stored on the device in the secure element chip, where it is impervious to any known attack and highly secure.
6What do you do if the device is damaged lost? Is it water proof?
If the device is lost or damaged, you can use your recovery phrase to restore the wallet, either using a new ATWallet, or a software wallet. This makes it very important to store your recovery phrase safely and securely, in a different location than you keep the ATWallet. The recovery phrase can be used by anyone to recovery your wallet, so it's essential to keep this information safe. Contact us if you have further questions.
7How often should I charge my AT.Wallet?

3My pc has the large old usb-a connector, my android has usb-c, my ipad has lightning - Do I need to buy an adapter also?
This security key is designed primarily to work with Windows PC and Mac, so it'll work fine with your PCs with USB-A connectors.
Chances are, your iOS and Android devices already have built-in biometric authentications. Furthermore, there are authenticator apps available on both OS for passwordless logins.
4How is mac and iOS compatibility? i am wondering why this isn't more popular as a fido2 fingerprint that works for mac. how compatible is it really?
For Mac OS, the ATKey.Pro is compatible with the following browsers: Edge and Chrome (FIDO2, U2F); Safari (U2F).
On iOS, it is compatible using Safari and U2F, assuming you have an Apple branded USB adapter. Note that the ATKey.Pro cannot be used to enter the phone's PIN.

ATKey.Pro
1 I’m trying to use Windows Hello feature to login to my PC. I’m currently using Windows 10 1909. Can you provide me instructions as to how to configure the key to be used as Windows Hello?
Based on the Microsoft definition, FIDO2 Key (ATKey Pro) for the Windows Hello app was built on the Companion Device Framework and is only used to unlock user accounts. Therefore, the user must first log into their account, lock the system, and then use the ATKey Pro for unlocking the device.
For more information regarding the Companion Device Framework, please check the link below.
https://docs.microsoft.com/en-us/windows/uwp/security/companion-device-unlock
Therefore, if you expect to login Windows Hello by using the FIDO2 key, currently, no FIDO2 keys can achieve it due to the Microsoft framework limitation. You can use your FIDO2 key to unlock (logon) the device through Windows Hello feature. The login feature only supports when you are using the Microsoft Azure AD account.

3I did update the firmware, but it seemed not to succeed and nothing shows up after the firmware update.
After the firmware upgrade, you will need to plug the ATKey.Pro off, then re-insert to the USB port. It requires such reboot progress (after re-insert to USB.) LED will be in WHITE for 10~15 sec to reboot, and then the new firmware is ready.
ATKey.Card
1I want to use NFC to log in to my PC, but it keeps connect ATKey.Card with Bluetooth.
After Power ON, BLE will start to broadcast. It needed you to verify fingerprint, NFC will then be turned ON for 15 sec.; BUT if BLE connected, fingerprint matching is for BLE; if your host is PC (Windows or Mac or Chormebook), we recommend you turn off your Bluetooth of PC to avoid BLE/NFC conflicts to Card.
