While new technology brings convenience, it also brings new security risks to users

Although the e-wallet supports setting character passwords, when the user’s e-wallet is stolen, hackers can still obtain the user’s payment password and steal funds through brute force cracking, Trojan monitoring, etc.

This makes it difficult for such electronic wallets to undertake the safe storage and use of users' daily funds, especially for users with large sums of money, if the electronic wallet is stolen, it may cause huge property losses

At the same time, e-wallet software is usually installed in the hard disk of the computer, which is inconvenient for users to use anytime and anywhere, and does not have mobile features.
