Part 8/11:
Expanded GPG tools, enabling users to generate, sign, and verify files or messages using hardware-backed keys, which is especially appealing for PGP and encrypted messaging workflows
Plans to support multi-signature setups and descriptor management, simplifying complex wallet architectures
Limitations and Important Considerations
While the integration brings powerful security benefits, certain limitations are noteworthy:
The SATA chip cannot be used as a seed backup. Seeds stored on the smart card cannot be recovered back into the seed signer device. It’s solely a signing and address derivation tool.
2FA support via SATA chip is limited; it only works with specific Electrum-based protocols, not with SeedSigner’s current features.
