What You Need Before You Start

Supported devices for creating a biometric passkey:

Mobile: Devices running iOS 16.0.0 / Android 7.0 or above

How to Set Up a Biometric Passkey in the Hotcoin App

Step 1: Create a Passkey

1. Go to your Profile Center and tap the > icon next to the Account Security menu option.

2. On the Create Passkey page, tap Continue to proceed, and verify your identity using the security method(s) linked to your account.

3. After completing the security verification, you can create a passkey on this device.

4. After successfully creating a passkey, you can view the details on the Passkey page and edit the passkey name to help differentiate between devices.

💡 Next time you log in, you can choose to use your passkey for a password-free login experience.

Step 2: How to Log In with Your Passkey

1. Go to the App login page, enter your account, and tap “Next”.

2. The system will prompt that you can Authenticate with a passkey. After verifying the passkey, you can log in without entering a password. You may also choose “Log in with password” to continue.

Step 3: How to Rename Your Passkey

You can go to Profile Center > Account Security > Passkey to rename your passkey for easier identification.

Note: Changing the passkey name only updates how it appears on Hotcoin's passkey management page. To change the actual device name (e.g., in Chrome), go to Manage Devices > Linked Devices in your Chrome browser.

Step 4: How to Delete Your Passkey

Each account can store up to 10 passkeys across different devices. If you exceed the limit, you can delete unused ones—but note that doing so may lower your account or device security. Please consider the risks before proceeding.

💡 Kind Reminder:

Keep your biometric passkey secure. If it's lost, stolen, or compromised, contact us immediately.
Never share your passkey or login credentials with any third party to avoid potential asset loss.
