Three keys protect your money.

Bitkey is a 2-of-3 multi-signature wallet. That means there are three private keys protecting your money. One's on your phone, one in your hardware device, and one held for you on the Bitkey server.

You always need two out of three keys to sign a transaction, giving you extra protection. And because Bitkey only holds one key for you, and you hold two, Bitkey can’t move your money without you.

How your three keys work.

How your Bitkey hardware works.

Protect savings at home.

Your Bitkey hardware works with your mobile app to protect your savings. To access the money protected by your hardware, unlock it with your fingerprint, and tap it with your phone. It connects to your phone via NFC, so you never have to risk plugging it into a computer.

Your keys work together.

Your hardware key and mobile key work together to co-sign transactions, or to change your security settings or spending limits. So you can go out and about, knowing that even if someone has your hardware, they can’t access your money.

How your Bitkey app works.

The home to manage your money.

Your Bitkey app is for managing your money with your hardware, and setting rules around security and spending. Use the app to send, receive, and transfer bitcoin, change your security settings, or start a recovery process.

Safe spending on the go.

For added protection, you can set an optional daily spending limit on your phone. Your mobile key works with the server key to co-sign transactions up to your daily limit, so you can spend safely on the go, knowing even if someone can access your phone they can’t access all your money.

Recover if you lose your phone.

Replace your phone.

If your phone gets lost, stolen or damaged, download the Bitkey app onto a new phone, and sign in to your cloud account via Google Drive or iCloud.

Authorize recovery with hardware.

Once you’re signed in to your cloud account, unlock your hardware and tap to your phone to unlock the encrypted mobile key backup and recover your wallet on your new phone.

Recover if you lose your hardware.

Follow recovery steps in the app.

If your hardware device gets lost, stolen, or damaged, tap a button in the app to start the recovery process. This triggers a 7-day security waiting period, and you'll receive security notifications via SMS or email to confirm you’ve requested hardware recovery.

Transfer to your new hardware key.

Once the security waiting period is over, set up a new Bitkey hardware device, pair it with your phone, and transfer your wallet balance to your new keys.

Set up your trusted contacts.

When you set up your Bitkey for the first time, you can set up ‘trusted contacts’ in the app. Your trusted contacts download the Bitkey app and agree to help you access your money if you lose your wallet.

Send a code to your contacts.

If you lose your phone and hardware, you can download the Bitkey app on a new phone and share a code to your trusted contacts to verify you. Once you’re verified, you can recover your mobile key from the cloud, and complete the process to replace your hardware device.
