I just found out that my Binance wallet has not been backed up quickly, and I recommend everyone without a quick backup to back it up.
With a quick backup, restoring the wallet only requires Binance security verification.
If there is no quick backup, you need "recovery password" + "Google Drive (Android) or iCloud (Apple)" or "backup QR code".
How to quickly back up?
Wallet home page top left corner - Wallet Management - Click on Wallet Name - Backup Management - Quick Backup.
