# Threshold Signatures

Our use of Threshold Signature Scheme (TSS) technology allows you full wallet access without requiring all five Guardian devices to be active. Key splitting ensures your private key remains hidden and unreachable, with TSS enabling you to use your wallet without all Guardian devices online.&#x20;

To access your wallet, only 3 out of 5 guardian devices need to be online - typically you and Gridlock. If Gridlock becomes unavailable, your guardians are in place to ensure fund recovery remains possible.
