# Sanctum Adds 2-of-3 Multisignature Security Across Its Wallets By Simon Yoon Canonical URL: https://www.tokenpost.com/news/technology/51272 Published: 2026-11-08T02:08:53.000Z Updated: 2026-11-08T02:08:53.000Z Section: Technology > The company says one lost key will not lock users out and one leaked key will not be enough to compromise access. Sanctum says its wallets have adopted a 2-of-3 multisignature setup, a change intended to preserve access after key loss and prevent one exposed key from compromising a wallet. In this arrangement, two of three keys are needed to authorize a transaction. Sanctum says losing one key will not lock users out, while a single leaked key will not be enough to compromise access. Multisignature wallets can shift risks among keys, devices and transaction approvals. A [previous look at multisignature security and key risks]() described those trade-offs. ## Links in this article - [previous look at multisignature security and key risks](https://www.tokenpost.com/news/technology/39528)
