Today we will talk about the security issues of the Binance non-custodial wallet.

A group member lost 1900U and there is currently no way to recover it (likely gone).

Yesterday, a group member reported:

Previously, the group member used an iPhone's Face ID to automatically create a wallet.

During this process, after verifying the authenticator and email verification code,

Face ID directly created the wallet (there was no password input step).

Then a few days ago, he intended to update the Binance app.

The Binance wallet displayed that the app needed to be uninstalled and reinstalled.

When he reinstalled the wallet and wanted to use the web3 wallet,

it prompted for the wallet recovery step.

Since he did not save the QR code earlier and there was no password step,

even though he has contacted Binance official staff, it seems there is no way to recover it.

As shown in the video operation:

There was no password input at all.

The group member mentioned during communication that he had input the password,

but both sides have their own claims, and then it shows the iCloud backup.

Here, a reminder to everyone:

Whether you are using Android or iPhone (especially iPhone Face ID),

1. After creating, make sure to back up the QR code.

2. Enter the backup password and remember the backup password.

3. Even if uploaded to the cloud, there can still be loss situations or information not syncing and getting deleted.

4. Regularly verify the QR code.

Then I would like to give a suggestion to Binance web3 wallet staff:

When users use Face ID,

it would be good to remind them to back up the QR code and enter the recovery password.

Otherwise, like in the video, many people probably haven't backed up.

Adding an extra reminder feature would improve the user experience!
