How Keyholding.app Works:
Lock your physical key in a safe or lockbox with a combination. Upload the secret combination to the app. It stays hidden until the timer runs out and it's time to unlock.
Lock your key
Put your physical key in a lockbox with a resettable combination or a safe that uses a code to unlock. Set a random combination without looking.
Upload the combination
Take a photo of the combination or enter the code, then upload it to your lock in the app.
Scramble the code
After uploading, scramble the lockbox combination and delete the photo. The secret becomes inaccessible until the timer expires or your Keyholder reveals it.
