Digital asset security

Make sure your digital assets are safe with these simple tips.

Digital assets like Bitcoin, Bitcoin Cash and Ethereum are 'peer-to-peer.' This means you can send them anywhere in the world without asking for permission. It also means you - and you alone - are responsible for protecting your assets.

Like a vault protects physical assets, the Bitcoin.com Wallet protects crypto assets - and in both cases, you need the right access key. However, since the Bitcoin.com Wallet is 'non-custodial' no third party (neither Bitcoin.com, nor anyone else) holds the key. It's just you. This means you have to be very careful about how you store your key. If you lose your key, you lose access to your cryptoassets.

Backing up your wallet

When you first install the Bitcoin.com Wallet on your phone, you have the option of setting up biometrics or a PIN. This acts as the key to your wallet, but what happens if you lose or break your phone?

That's why it's important to 'back up' your Wallet. Backing up your Wallet just means you're creating a backup key and storing it outside of your phone.

There are a few ways to do that but the easiest is surely the cloud backup service. Here, you create a single custom password that decrypts a file stored in your Google Drive or Apple iCloud account. If you lose access to your device, you can reinstall the Wallet app on a new device, enter your password, and you'll again have access to all your cryptoassets.

Note: To use the cloud backup service, you'll first need to login to either Google Drive or Apple iCloud through the Wallet app.

Alternatively, you can create manual backups. In this case, you'll be assigned a random set of 12 words (a "passphrase") for each of the digital wallets within your Bitcoin.com Wallet.* Then, when you reinstall the app on a new device, you'll need to enter your 12-word passphrase to gain access to each wallet.

*Your Bitcoin.com Wallet consists of multiple wallets, one for each of the blockchains we support. This means you have a BTC wallet, a BCH wallet, and an ETH wallet. You can also create as many additional wallets as you want. For this reason, it can be extremely difficult to manage all your passphrases - and that's exactly why we created the cloud backup: It's one simple password for all your wallets!

Password management best practices

Whether you choose a single password that decrypts your entire Wallet or multiple auto-generated 12-word passphrases corresponding to each wallet in your Bitcoin.com Wallet, it's essential that you adhere to password management best practices.

Firstly, you should never store your passwords in digital form, as doing so opens you up to the possibility of having them stolen by hackers. This includes taking screenshots or digital photos of your handwritten passwords.

For most people, the best strategy is to physically write down the password/passphrases on a piece of paper and store that paper somewhere safe. If the crypto assets in your Wallet are worth a lot, you'll want to (manually) make copies of the paper, and store those copies in separate locations (eg. one at your house, one at a family member's house).

While all of this may sound a little complex, it's important to remember why it's so important: when you use a non-custodial wallet, you - and you alone - are in control of your funds.

Note that for manual backups, anyone with the passphrase can gain access to your wallet (and steal the assets in it) while for the cloud backup service, you have an extra layer of protection because an attacker will need to first get into your Google or Apple account, then enter the additional master password you created. If you set up your Google or Apple account with 2-Factor Authentication, you're making it very difficult for a hacker.
