Wallet Authentication

Overview

Authentication may use passwords, device keys, biometrics, passkeys, hardware tokens, session credentials, or cryptographic wallet signatures. It answers who or what is presenting a request, while separate authorization logic determines which wallet actions that identity may perform.

Signing a generic message can expose users to phishing, replay, cross-domain reuse, or confusing consent if origin, nonce, purpose, and expiration are unclear. Strong login also fails when recovery, device enrollment, sessions, support processes, or front-end integrity are compromised.

Wallets should use domain-bound and fresh challenges, clear signing prompts, secure enrollment, rate limits, session protection, and phishing-resistant methods where possible. Recovery and new-device flows need equivalent assurance, while authentication logs avoid storing signatures or data that enable replay.

For Wallet Authentication, production scope should name the relevant keys, signing policies, accounts, addresses, transactions, recovery paths, and custody boundaries, the decision being supported, the accountable owner, and the time and jurisdiction boundaries.

Wallet authentication verifies the identity or possession claim of a person, device, or service requesting access to a wallet interface. Wallet authentication establishes identity or possession, but transaction authority requires separate, context-bound authorization and secure enrollment, sessions, and recovery.

For Wallet Authentication, the trust decision should establish the identity or possession claim of a person, device, or service requesting access to a wallet interface and bind the result to the requested action and protected resource. Teams should test issuance, storage, validation, expiry, revocation, recovery, and privileged override for identity proof and credential state, rather than checking only a successful request. Logs concerning the Wallet identity check and identity proof and credential state should support investigation without exposing reusable secrets or unnecessary personal data.
