Software · Tenant-facing
Keyless access for every tenant — at any time, no staff required.
One Access App lets tenants open gates, doors, elevators, and individual spaces via Bluetooth, NFC, or internet. Bluetooth-based access works directly from the phone — no signal needed. No physical key. No NFC card. No interaction with staff, ever.
What the app does
The app handles the full tenant experience — opening doors, sharing access, reviewing history, and staying informed about security events. All from the phone they already carry.
Access
Via Bluetooth, NFC, or internet — with or without phone signal.
Sharing
Grant access by email address — no physical handover, instantly revocable.
Security
View access history and receive push notifications for security events.
Branding
Fully brandable — colours, themes, and app identity match your facility.
Secure openings
Reliable access — even without a phone signal.
One Access App opens gates, main doors, elevators, corridors, and individual units via Bluetooth, NFC, or internet. Bluetooth-based access works directly from the phone without an internet connection — so tenants can enter their space reliably even in large buildings with poor connectivity.
All connections are encrypted. Data is stored on secure, German-hosted servers.
Access sharing
For a family member, a delivery driver, a removal company.
Tenants grant access to anyone directly from the app — all it takes is an email address. No physical handover, no NFC card to prepare. And access is revocable just as easily, the moment it's no longer needed.
Tenants choose exactly how long the access lasts — permanently until manually revoked, for a defined time window, or as a single-use pass that expires after one opening.
Custom branding
Built for operators who care about brand.
The app your tenants use every day can carry your facility's identity. Operators customise colours, themes, and brand elements — in both dark and light mode. A consistent brand presence reinforces your facility's digital positioning and keeps tenants oriented.
The interface is designed for ease of use regardless of how many doors a tenant navigates. List and grid views, quick search, and a favourites section make finding the right space instant.
