About

Proton Authenticator is a privacy-first two-factor authentication app that generates time-based one-time passwords to add an extra layer of login security for online accounts beyond just a password, so users can secure accounts across all their devices. It is open source and uses end-to-end encryption, meaning all cryptographic operations and secret keys are generated and stored locally, and even Proton cannot see your unencrypted 2FA data, offering transparency and strong privacy by design. Users can sync 2FA codes across devices with encrypted backups (including via iCloud or a Proton Account), import existing codes from other authenticator apps, and export them if needed, giving flexibility and control over 2FA secrets without vendor lock-in. Proton Authenticator is free to use, has no ads or tracking, and supports secure practices like biometric locks and offline access, so users can generate login codes.

About

SignOps is a hosted developer API for adding push messaging and sign-in flows to web and mobile applications. Developers can register devices under their existing user IDs, send Android, iOS and web push messages to users or topics, schedule messages, use templates, and review delivery events. The service also provides phone-based login approvals with number matching and biometric confirmation, passkey sign-in on a customer’s domain, TOTP authenticator codes with backup codes, and email one-time passwords. REST endpoints, server SDKs, mobile and web SDKs, a team dashboard, and signed webhooks support integration with an application’s existing backend and identity provider. It is designed for developers and teams building applications that need notifications, passwordless authentication, or additional sign-in verification.
