Sentry.co is a “Self-Sovereign Authentication and Password Management” product for personal credential management and authentication use cases. Its core proposition is to automatically sync credentials in the background over local connections, minimizing reliance on the cloud and reducing exposure to online attacks and cloud breaches. The site indicates that the product is still in an “Available soon / TestFlight soon” stage.
In terms of protection features, it covers many capabilities commonly found in modern password managers: passwords, Passkeys (marked as coming soon), AutoFill for Safari and most native apps, TOTP/HOTP one-time codes, PIN codes, and Face ID/Touch ID biometrics. Deployment is clearly Apple-ecosystem focused, with explicit support for iPhone, iPad, and Macintosh, requiring iOS 18+ and macOS 15+. Its standout feature is local offline sync, which can work even when devices are on standby. Secure sharing is also positioned around offline sending, protected by end-to-end encryption and rolling PIN codes. For backups, data can be stored on every device owned by the user, with support for USB drives or cloud backups as well.
Pricing is fairly clear: 2 devices are free, while the paid plan costs $1.99/month or $19.99/year. Payment methods are not disclosed. The page does not provide information on compliance certifications such as SOC 2, ISO 27001, or GDPR, nor does it disclose enterprise-grade SLA, audit logs, centralized policy controls, or alerting capabilities. As such, it looks more like a consumer-focused personal tool than an enterprise IAM or PAM product.
Its main strength is a clear philosophy: credentials are 100% user-controlled and do not depend on the cloud. Offline sync and offline sharing provide differentiation in both privacy and usability. The disclosure of 35+ open-source modules, continuous testing, and GitHub Actions quality checks also adds some transparency. The drawbacks are also obvious: the product has not officially launched yet, Passkeys are not finished, support appears limited to Apple platforms, cross-platform capability is lacking, and information on enterprise management, compliance certifications, and customer support is missing.
It is best suited for privacy-conscious individual users or small-scale users who are all-in on the Apple ecosystem and want to avoid a cloud-based password vault. It is not suitable for organizations that need Windows/Android support, team permissions, audit alerts, or compliance reporting. Access from China is not stated in the available text, so it is unknown; payment availability is also unknown. Alternatives include 1Password, Bitwarden, Apple iCloud Keychain, KeePassXC, and Dashlane.
