Pay Passkey FAQ

When using Pay, it's important to understand how your Pay account and Passkey work together to ensure secure and seamless transactions. Your Pay account is powered by a smart contract wallet, and a Passkey is automatically created when the account is set up. This Passkey is essential for authorizing all Pay mode transactions, acting as a secure signature unique to you. It's worth noting that for your security, we can't access, generate, or modify your Passkey in any way.

How do I create a Pay Passkey?

• A Passkey is created automatically when a user sets up a Pay account.

• Users need to log into cloud services for backup during Passkey creation.

  • Android users must log into a Google Play account.

  • iOS users need to log into their iCloud account.

Where can I manage the Pay Passkey?

Head over to Settings > User Center > Security Settings > Passkey Management.

Note:

• Users can rename or delete Passkeys.

• Users can't delete the last remaining Passkey.

FAQ

1. What system versions are supported by Passkey?

• Recommended: iOS 16+ and Android 9+.

• Android devices must be able to log into Google services.

2. How do Pay Passkeys differ from exchange Passkeys?

• They're two completely independent Passkey systems.

• Users may have an exchange Passkey for exchange logging in and trading, but a separate Pay Passkey must be created for their Pay account.

• The Pay Passkey is used solely for signing transactions in Pay mode.

3. How does Pay Passkey synchronize across devices?

• Users can log into the same exchange account on different devices

• Switch to Pay mode, and initiate a tx which will trigger the Passkey synchronization process

• Now there are two ways to sync Passkeys

  • Users can log into their iCloud/Google account (that already created Pay Passkeys) to sync their Passkeys.

  • Alternatively, they can create a new Passkey with the help of the old phone

4. How does Pay Passkey sync multiple chains?

• Users must "activate" each chain, which deploys the created Passkey to that chain.

• The activation status of one chain can be synchronized across multiple cloud accounts (devices).

5. What to do if the Passkey limit is reached?

• A maximum of 3 Passkeys can be created per Pay account.

• Users must delete unnecessary Passkeys in the Passkey management center.

6. When might a user need to reset their Pay Passkey?

When logging into the same Pay account across devices:

• Unable to log into their old cloud account to sync Passkey.

• Unable to use the old device to sync Passkey.

Users then can select Device Unavailable option to initiate a Passkey reset through customer support.

7. What's a Passkey reset?

• A process that was initiated by users to redeploy a new Passkey on a specific chain.

• The system will verify that the user is the owner of the Pay account using ZK-Email technology

• Users will need to send a reset request email from their current email that is bound to their exchange account

• Old Passkeys on that chain will be deleted post-reset.

• Users can use Pay mode functions on that chain without additional steps post-reset.

8. What are the limitations for resetting a Passkey?

• Only activated chains can be reset; unactivated chains do not need a reset.

• The TRON chain does not support Passkey resets.

• Users can reset only one chain at a time.

9. If my Passkey is moved to a non-supported device, what happens?

As long as the identity verification address is in a supported region, Pay mode will display normally. However, users may not be able to initiate Pay transactions if the passkey is not supported by the device.

10. How do I withdraw assets from unsupported devices?

Device must support passkey, which will be used to sign withdrawal transactions.

11. What if the only one Passkey is lost?

If there's only one passkey left, it cannot be deleted. And if you lose access to the passkey, you can contact our customer service for a passkey reset.

12. Are there any usage restrictions after resetting a Passkey?

All Pay functions can be used immediately after a successful reset.

13. Does the email used for resetting depend on the cloud account used?

Passkey syncing depends on the cloud account that originally created the passkey. However, passkey resetting depends on the current exchange bound email.

14. Can I reset multiple chains during the process?

Currently, you can only reset one chain at a time due to technical constraints.
