Best practices for wallet security
- Using strong passwords and two factor authentication (2FA): by using strong password your wallets is less vulnerable to hacking attacks and by introducing a second layer of verification in addition to a password, 2FA seeks to improve security and makes it harder for unauthorized individuals to gain access to your crypto currency account.
2FA? Usually only custodial service and multi-signature wallet (where one of the private keys owned by 3rd party) offer this option, which may not you want.
- Backing up data: ensure that all digital files are encrypted with strong password. Regularly backup new update i.e whenever you makes changes to your wallets, such as adding new addresses or generating new keys, update your backup to reflect these changes.
Regular backup isn't mandatory, since most wallet these days actually create HD hierarchical deterministic. You always generate same key/address based on recovery words or master private key you backed up when creating the wallet for first time.
