# Security & Technology

- [Overview](https://docs.vultisig.com/security-and-technology/overview.md): How Vultisig security works. Threshold Signature Schemes (TSS), DKLS23 protocol, keysigning process, and cryptographic foundations explained.
- [Keysign](https://docs.vultisig.com/security-and-technology/keysign.md): How Vultisig keysigning works. Multi-device threshold signing process for Fast Vaults and Secure Vaults. QR pairing, verification, and broadcast.
- [TSS Actions](https://docs.vultisig.com/security-and-technology/tss-actions.md): TSS operations explained: Key Generation (vault creation), Key Signing (transactions), and Resharing (device changes). Core MPC actions.
- [How GG20 Works](https://docs.vultisig.com/security-and-technology/how-gg20-works.md): GG20 threshold signature protocol explained. How Vultisig's legacy TSS works: secret sharing, MPC signing rounds, and security model.
- [How DKLS23 Works](https://docs.vultisig.com/security-and-technology/how-dkls23-works.md): DKLS23 protocol deep-dive. Vultisig's modern TSS: faster signing, fewer rounds, improved security. Developed with Silence Laboratories.
- [Difference to Multi-Signatures](https://docs.vultisig.com/security-and-technology/difference-to-multi-sig.md): TSS vs Multi-Sig explained. Why threshold signatures are superior: no private key reconstruction, chain-agnostic, lower fees, better privacy.
- [Difference to Passkeys](https://docs.vultisig.com/security-and-technology/difference-to-passkeys.md): TSS vs Passkeys comparison. Why threshold signatures offer better crypto security: multi-device, no single point of failure, true self-custody.
- [Emergency Recovery](https://docs.vultisig.com/security-and-technology/emergency-recovery.md): Emergency recovery tool for Vultisig vaults. Reconstruct keys if TSS software becomes unavailable. Last-resort fund recovery process.
