Backing up your Wallet effectively means creating a password that allows you to access your Wallet in the event you lose or damage your phone.
⚠️ WARNING ⚠️
Bitcoin.com does not store your password or secret phrases! If you lose access to your device, the only way to access your funds is with your password / secret phrase. This is why it's extremely important to back up your Wallet.
What does it mean to back up my Wallet?
Like a vault protects physical assets, the Bitcoin.com Wallet protects crypto-assets - and in both cases, you need the right access key.
Backing up your Wallet means creating a digital key (in the form of a password or passphrase) that allows you to access your Wallet in the event you lose or damage your phone. Importantly, this digital key is stored outside of your phone.
Why should I back up my Wallet?
When you first install the Bitcoin.com Wallet on your device, 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 device? If you haven't backed up your Wallet, your digital assets will be lost forever.
Can't I just ask Bitcoin.com to restore my wallet?
In a word, no.
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 is essential for making your Wallet "permissionless," meaning you never have to ask for permission to use your crypto-assets (unlike with custodial services like banks and credit cards).
However, with great power, comes great responsibility: If you lose your key, you lose access to your crypto-assets — forever!
How do I use my backup?
If you lose or damage your phone, just reinstall the Bitcoin.com Wallet app, then enter your backup password or passphrase(s). You'll again have access to the crypto-assets in your Wallet. Here's a guide for importing/restoring a Wallet from a backup.
I'm ready to back up. What should I do?
The Bitcoin.com Wallet provides you with two ways to backup your wallet. You can use either or both.
Cloud backup service
Here, you create a single custom password that decrypts a file stored in your Google Drive or Apple iCloud. 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 of your crypto-assets. Not only that, whenever you add more wallets within your Bitcoin.com Wallet, your backup file will automatically sync. This means you never have to worry about creating a new backup for each new wallet you create!
🔍 Note: To use the Cloud Backup Service, you'll first need to login to either Google Drive or Apple iCloud through the Wallet app.
Cloud backup instructions
Tap on the Settings tab (bottom right of the home screen).
Select "Backup & security."
If you haven't already, you'll need to sign in with Apple or Google.
Create a master password.
You'll use this password to recover your Wallet if you lose or damage your phone. It's non-recoverable, so you should write it down and store the paper somewhere safe. See our article on crypto-asset security for information on password management best practices.
🔍Note: Your master password must be at least 8 characters long and include upper and lowercase alphanumeric characters and at least one number.
Tap the "Create Recovery File and Sync" button.
Your entire Bitcoin.com Wallet is now backed up!
For manual backups, you'll be assigned a random set of 12 words (a "passphrase") for each of the crypto-wallets within your Bitcoin.com Wallet.* Then, when you reinstall the app, you'll need to enter each wallet's 12-word passphrase to gain to access each wallet.
*Actually, your Bitcoin.com Wallet consists of multiple wallets, at least one for each of the blockchains we support. This means you have a BTC wallet, a BCH wallet, and an ETH wallet. Within your BCH wallet, for example, you may have several crypto-assets that live on the Bitcoin Cash blockchain; like BCH, USDT, and so on. When you backup your BCH wallet, you're backing up access to all the crypto-assets stored in that wallet. Also, you can create as many new wallets as you want just by tapping on the '+ADD/IMPORT' button on the app's home screen. When you use the cloud back up, all your wallets are backed up automatically and accessible by a single password of your choosing, but when you manually backup, you'll need to manage all your secret phrases separately.
Manual backup instructions
Tap on the Settings icon.
Select "Backup & security."
Go to "Manual backup."
Choose the wallet you'd like to backup. Eg. Tap on "My BCH wallet."
Write down your 12-word passphrase.*
