Fast, auditable authentication for crypto wallets and financial platforms.
Live
Overview — Secure, Yet Simple 🗝️
Uphold Login™ reimagines wallet authentication by eliminating brittle passwords and replacing them with proven cryptographic flows. Our platform enables passwordless journeys using device-based biometrics, hardware keys (FIDO2), and short-lived session tokens that are easy for users and uncompromising for security teams. The result: fewer support tickets, faster transactions, and higher conversion during sign-in and checkout.
Core capabilities
🔑
Hardware-backed keys
Retain cryptographic control — private keys stay on a user's device or hardware token, never shared with servers.
🧭
Device trust & session orchestration
Smart device attestations and policy-driven sessions reduce re-auth frequency while keeping sensitive flows protected.
⚡
Instant sign-in
Approved devices sign in with micro-latency — ideal for power users and high-frequency traders.
🛡️
Compliance-ready audit trails
Immutable logs, configurable retention, and export utilities for audits and investigations.
How Uphold Login protects wallets
When a user registers, the client creates a secure keypair and performs a device attestation. The public key is stored with a minimal profile on our servers; the private key remains isolated. During sign-in, the platform challenges the device to prove possession of the private key and verifies device health. If the device passes policy gates, a signed session token is issued. For high-risk transactions, Uphold Login supports adaptive step-up authentication, requiring a hardware key tap or biometric verification.
For teams — integrate with confidence
Built for developer velocity, Uphold Login provides clear REST APIs, lightweight client SDKs, and integration guides for WebAuthn and OpenID Connect. Identity teams can define role-based access, configure step-up rules for sensitive operations, and export detailed audit logs for compliance. Whether you run a custodial exchange, a non-custodial wallet provider, or an institutional trading desk, our team will help you design a flow that balances security and user experience.
Migration & recovery
We support progressive migration paths: allow existing users to opt into passwordless sign-in while maintaining legacy fallback for verification. Lost-key recovery uses multi-party guardians and time-locked fallback processes to minimize fraud while restoring access reliably.
