Any 2 of the 3 keys are required to authorize a transaction
Stored securely on your mobile device
Physical device for ultimate security
Encrypted backup for recovery
Transaction Authorization
Requires any 2 keys to complete a Bitcoin transaction
If you lose your phone or hardware device, you can still access your Bitcoin using the remaining key plus the cloud backup.
