Your users do, with true self-custody. In a passkey account, the passkey that signs lives on the user's devices and syncs end-to-end encrypted through iCloud Keychain or Google Password Manager. Every transfer needs the user's approval or a permission they grant, so apps and agents get permissions, never the user's keys. Nethermind audited the account and permission contracts in October 2025 and March 2026, and you can host the passkey server yourself.
