A digital wallet is a secure electronic system that allows users to store, manage, and transfer digital currencies, cryptocurrencies, or payment information. It can be accessed via computers or mobile devices and is commonly used for online purchases, peer-to-peer payments, and managing crypto assets. Digital wallets use encryption and authentication measures to protect sensitive data, but they can be targets for cybercriminals seeking to steal funds or personal information. Examples include Apple Pay, Google Wallet, and cryptocurrency wallets like MetaMask or Coinbase Wallet.
