Multi-Factor Security Shield

Overview

Multi-Factor Smart Accounts bring network-level multi-factor authentication to Radix, replacing single seed phrase control with configurable "Security Shields." Unlike account abstraction on other chains, Radix implements MFA directly at the protocol level via the Access Controller, eliminating single points of failure.

A Security Shield combines multiple authentication factors — phone, Ledger hardware wallet, Arculus Card, off-device mnemonic, or a trusted person — into a rule set that governs account access.

Rollout Phases

Phase 1 — Create & Sign (Live on Stokenet)

Users can configure a Security Shield and apply it to accounts or personas. The wallet enforces shield-based signing rules. Launched October 2025.

Phase 2 — Update Shield (Live on Stokenet)

Users can modify existing shield configurations and exercise recovery-related functions including timed delays. Launched December 2025.

Phase 3 — Recovery Without Backup (Upcoming)

The final phase enables account recovery when a primary device is lost or compromised, completing the full MFA lifecycle.

Mainnet Timeline

All three phases are being tested on Stokenet first. Once community feedback and testing is complete across all phases, the feature will be deployed to mainnet. The 2026 Strategy lists MFA Phase 3 completion and mainnet launch as an immediate Phase 1 priority.
