There is an "Advanced" button on the Guardians setup screen where you can change your required number of Guardians, but it is highly recommended to stick with the default settings for your first Vault creation: 3 total Guardians are recommended, with confirmations from 2 out of those 3 Guardians to recover your Vault. This gives you resilience in case one of your Guardians fails to respond. The simplest Guardian configuration to begin using is 1 trusted Person (e.g., your spouse) and 2 spare devices under your control (e.g., iPad and Macbook). In this case, you are still in control of recovery if the trusted person fails to respond, because your 2 spare devices that are configured as Guardians can be used to satisfy the 2-of-3 confirmations to restore your Vault. Further, based on this 2-of-3 confirmation setup, none of your individual Guardians or devices exposes you to risk if one of them is compromised or fails. This type of setup offers a careful balance of control, convenience, safety, and fault tolerance.
