Mobile credentials turn a resident's phone into their key. Residents sign in to the app to open their unit and building doors, share access with guests or deliveries where allowed, and, where the hardware supports wallet keys, unlock with Apple Wallet or Google Wallet without opening the app.

Physical keys and fobs get lost, copied and forgotten at move-out, and every one of them is a cost and a security gap. Residents already carry their phone everywhere. Turning it into their key means nothing to hand over at move-in, nothing to collect at move-out, and access that can change the moment a lease does.
The resident signs in to the property's app with a username and password, which ties the phone to their identity and their lease. The app then holds digital credentials for the doors they're allowed to use: their unit, the building entrances and the amenities their lease includes. The phone talks to the lock or reader over Bluetooth or NFC. With wallet credentials, the key lives in Apple Wallet or Google Wallet, so the resident holds the phone to the reader the way they would tap to pay, without opening an app first. Which options a door offers depends on its lock or reader.
Della handles the whole experience in one place. Residents sign in to Della Resident once and get access to their unit and the building doors their lease allows. From the same app they can create guest passes or delivery access where the property permits it, and, where the property's locks and readers support wallet keys, add their key to Apple Wallet or Google Wallet so the door opens with a tap. Because Della OS is connected to the PMS, credentials are issued when the lease starts and removed when it ends, across every supported brand of lock and reader in the portfolio.
No keys or fobs to buy, cut, track or collect. Faster move-ins, cleaner move-outs, fewer lockout calls, and a resident experience that matches how people already use their phones.
Not with wallet keys. Once a resident adds their key to Apple Wallet or Google Wallet, they unlock by holding the phone near the reader, much like paying with it. Residents can still open doors from Della Resident whenever they prefer, and the app remains the place to manage guests, deliveries and everything else.
Yes, where the property allows it. Residents create guest passes or delivery access in Della Resident, limited to the doors and times the property permits. Passes end on their own and are recorded, so staff can see who was let in and when.
It's removed. When the lease ends in the PMS, Della OS removes the resident's access through supported systems, so former residents can't keep entering the building and staff don't have to remember to revoke each credential.
Not natively. Wallet keys need locks and readers that support them. Where the hardware does, Della turns it on through the same resident experience; where it doesn't, residents open the door from Della Resident or use a physical credential. Your integration partner confirms what each door supports.
Yes. Phones work alongside fobs, cards and PIN codes wherever the hardware supports them. Many properties keep a physical option for residents who prefer one, for staff and contractors, or as a backup.
