There are some situations where you may want to reset the Mylio Photos application on one of your devices, including:
Re-configuring how the device is set up
If you're getting started with Mylio Photos and want to change fundamental pieces of your configuration, including where the Mylio System Folder is stored, which folders are linked, and where the Linked Folders reside, resetting is often the most straightforward solution.
Adding the device to a different Mylio Photos account
Mylio Photos is designed to be signed into one account only once per device. Once a device has been logged into an account, that account remains locked to that device. To add the device to a different Mylio Photos account, the application must be reset.
Troubleshooting an issue
If you have a fully synced Mylio Photos vault, resetting the Mylio Photos application on a specific device that is not functioning as expected can be a good troubleshooting step.
NOTE: Factory Resetting Mylio Photos on a device completely resets your Mylio Photos Library on that device. When you sign in to the Mylio Photos application again, you are adding a new device to your Mylio Photos account. Your Mylio Photos Library will automatically re-sync from any active devices that remain on your account if you are a Mylio Photos+ subscriber and those devices meet the criteria to sync.
To start over on all devices with an empty Mylio Photos Library, please follow the steps in the manual linked here.
Reset Mylio Photos on a Computer
Please ensure your photos have finished syncing to a Mylio Photos Vault, or that you otherwise have a full backup of all your photos, before resetting Mylio Photos on a computer.
Open Mylio Photos on any device, open the Mylio Photos Dashboard, and select Devices
Select the computer you want to reset and choose Unregister Device
Quit Mylio Photos on the computer you unregistered if it's currently open, then hold the Alt (on Windows) or Option (on macOS) key when re-launching the application to display the Support Options Window
Choose Factory Reset Mylio Photos and follow the prompts
Mylio Photos has been reset on your computer. You'll be shown the sign-in screen, where you can sign in using your Mylio Photos account credentials. Because you're adding a new device, your Mylio Photos Library will be empty when you first sign in. When the sync criteria are met, your library will re-sync from one of your remaining active devices.
A new Mylio System Folder is created on your computer in the default location (the User folder) and the old one is automatically renamed "Mylio.old". The Mylio.old folder can be moved, renamed, or deleted. If you wish to move your new Mylio System Folder from the default location, it's best to do so now, before your library re-syncs.
