By Synology
Synology Secure SignIn is a proprietary authentication utility for Synology NAS hardware, providing push-based approval and OTP codes on iOS and Android.
The App DNA
What makes this app unique?
The tool removes the need for DSM passwords, but its current notification failures create a circular dependency that blocks access to network storage.
For Synology NAS administrators and users seeking secure, password-less access to their network-attached storage devices.
What does it look like?
Key features
Replaces DSM passwords with push notification approval, serving as a primary retention loop for Synology hardware.
Generates time-based one-time passwords for secondary authentication, acting as a standard security fallback.
How much does it cost?
The app functions as a free utility to support the primary hardware business, requiring DSM 7.0 or above.
Velocity
Maintenance developmentperformanceShow more...
The app is currently in a maintenance phase, with only one release shipped in the last 124 days. Development activity is limited to stability and performance improvements rather than new feature delivery. Given the current cadence, the app remains in a state of low-frequency updates focused on technical debt rather than user-facing expansion.

Key takeaways for Synology Secure SignIn
Where is it heading?
The market for authentication tools is shifting toward standardized, cross-platform solutions, leaving Synology Secure SignIn exposed due to its hardware-locked, proprietary design. Without a fix for the core notification failures, the app will continue to drive users toward third-party alternatives, undermining the security experience Synology intends to provide.
- Notification failures block hardware access, which erodes trust in the security tool and drives users toward third-party alternatives.
- The maintenance-only release cadence suggests that the current authentication tool is not a priority for active feature expansion.
The SWOT
- Proprietary approval mechanism replaces DSM passwords
- Apple Watch integration would reduce access friction

The proprietary nature of Synology Secure SignIn is a liability…
Read the full takeSince the last report: Synology Secure SignIn has undergone no functional changes, remaining in a maintenance-only state for over four months. The analysis now more explicitly frames the app's proprietary design as a liability that actively drives users toward third-party alternatives due to persistent notification and login failures.
Bottom line
Reliable notification delivery is the core requirement for hardware access, and the current failure rate creates a critical barrier for administrators. Addressing the authentication loop would stabilize the user base, as the current friction drives requests for third-party alternatives.
