Electra Protocol’s native wallets for mobile devices and desktop computers are so-called hierarchical deterministic wallets (HD wallets).
A HD wallet is an encrypted application commonly used to store the private keys for holders of cryptocurrencies. Anyone with a copy of both the private keys and password can control the cryptocurrency in the account. This means: anyone having access to your backup (such as wallet.dat) and the corresponding password, or the mnemonic phrase, will be able to access the wallet.
Be sure to place copies of your wallet.dat backup file (XEP Desktop Wallet) on different devices, such as an USB stick.
