When it comes to custodial wallets, such as mobile wallets and web wallets, the first thing you need to do is choose a wallet provider you can trust. Kraken and Coinbase both have strong track records as exchange wallet providers. Next, take advantage of all the security features offered by the exchange/provider. This includes ensuring strong passwords, biometric app security, and the use of 2FA.

For self-custodial wallets, seed phrase Security is the most important way to protect your private keys. A seed phrase consists of 12 or 24 words and serves as a way to restore your wallet if it is lost or damaged. As soon as you create your wallet, back up your seed phrase. Write these words down on paper, keep them in a safe place, and never share them. Don’t save it digitally by taking a photo, writing on a document, or saving it with password protection. Reputable self-custody wallet providers like BitPay will never ask you for a seed phrase. Outside of immediate family situations, only you have access to your seed phrase.
