We have three U100 locks. I’m trying to understand whether this is user error or a current limitation of the system.
Should it be possible to set up my family as users in the Aqara app, enroll their fingerprints once on a single lock, and then assign their access to the other locks from the app? Or is the only option really to physically bring everyone to each lock and re-register fingerprints on every device?
Related question: it would be extremely helpful to manage user access more granularly — for example, allowing User A to unlock Lock 1 only on weekdays from 8–11am, while restricting other locks or times.
Am I missing a setting, or is there a technical/security reason that user access can’t currently be managed by user + device + day/time?
Would love to know how others are handling this, or if Aqara has plans to expand this functionality.

@mjtruncale It sounds like you’re looking to streamline user management across multiple U100 locks—great question! Let’s break this down based on the current system capabilities:
Fingerprint Enrollment Across Locks
From what we know, the Aqara Smart Door Lock U100 requires fingerprints to be enrolled per lock via the Aqara Home app. There isn’t a feature to “sync” fingerprints across multiple locks after enrolling once on a single device. So, for now, each family member would need to physically register their fingerprint on each U100 lock individually. This seems to be a current limitation rather than user error.
Granular Access Control (User + Device + Time)
The U100 does support periodic passwords for temporary users, which can be set for specific time spans (e.g., 10am–2pm) and periods (e.g., every Monday). However, this functionality is limited to temporary users and tied to password access, not fingerprints. For general users (who can use all unlocking methods, including fingerprints), the system currently doesn’t support granular per-device or time-based restrictions beyond what’s set at the family or user role level.
Next Steps
Your idea for more granular control (user + device + day/time) is a great suggestion! Since this isn’t currently supported, I recommend sharing this feedback directly with the Aqara team. You can contact the Aqara Home App Customer Service Team (Profile > Help & Feedback > Customer Service) or scan the QR code:
This will help ensure your input is heard for future feature considerations.
Hope this clarifies things! Let us know if you find workarounds that work for your setup—community insights are always helpful.
