What are the device requirements to use a passkey?
A passkey requires a phone or computer that supports Face ID, fingerprint or a similar unlocking method, with the screen lock enabled.
Please note that HarmonyOS is not currently supported.
To utilize this feature through a browser, please update to Chrome 108, Safari 16, Edge 108 or Firefox 119 (or above).
To utilize this feature in the TradeUP app, please update to version 9.6.2.0 (or above).
If your device does not support Face ID or fingerprint recognition, you may use a physical security key (USB/NFC, which you need to purchase separately).
When adding a passkey, select the option to use a security key in the system dialog, then insert or tap it against your device as prompted.
If prompted to set a PIN, please contact the manufacturer or create one via Chrome under Settings > Privacy and Security > Security > Manage Security Keys.
Why can't I add a passkey?
In most cases, you can't add a passkey because your device does not have a device passcode set or its system version is outdated. If you use a password manager other than the one built into your system, it may not be supported.
What do I do if passkey verification failed or no passkey was found?
This will not prevent you from logging in.
Close the verification dialog.
Click "Switch to another verification method" at the bottom of the page.
Log in using your password or a verification code. You may then delete the non-functioning passkey and add a new one.
If you have deleted a passkey in the TradeUP app but it still appears at login, its record may still be stored on your device. Depending on your device, you can remove it by following these steps:
iPhone/iPad: Settings > General > AutoFill & Passwords
Android: Settings > Google > Password Manager
Mac: Passwords app or Keychain Access
Windows: Settings > Accounts > Passkeys
I switched to a new phone and my passkey didn't sync.
Apple users: Both phones must be signed in to the same Apple ID, with iCloud > Passwords and Keychain enabled.
Android users: Enable syncing under Settings > Google > Password Manager.
If your passkey does not sync, this is expected and will not affect your account. Simply log in using your password or a verification code, then add a new passkey for your new phone. Certain brands use their own password managers, which may not support syncing.
What should I do if I lose my phone?
A passkey is bound to the Face ID, fingerprint, or device passcode of the registered device only, and cannot be used by any other party to access your account. You should log in to another device as soon as possible and delete the passkey associated with the lost device.
Can I still use my password after adding a passkey? Do I still need a passkey if I use the TradeUP Authenticator?
Yes, you may continue to use all of these methods.
A passkey does not replace your password, 2-step verification, or SMS/email verification codes. It is advisable to retain these as backup login methods, such as when switching devices or using another device temporarily.
What is the difference between a passkey, password, and trading password?
Passkey: A digital credential created and stored on your device, secured by your Face ID, fingerprint, or device passcode. It replaces your traditional password with a faster, more secure login method.
Password: An alphanumeric combination that you set up and use to log in to your TradeUP account.
Trading Password: A separate credential used to authorize specific actions within your TradeUP account, such as placing orders. Unlike your login password or passkey, which verify your identity to access the app, your trading password provides an additional layer of security for sensitive actions taken within the TradeUP app.
