Open Settings → Security and use the password section to change your main LightDrive password.
- Enter your current password.
- Enter and confirm a new, unique password.
- Save the change.
The new password applies to the Vault. Update a Files or Calendar client if it deliberately stores the main password.
Connected-app credentials
Vault app passwords and LightDrive client passwords are separate credentials. Changing the main password does not change them.
- Review Vault app passwords and LightDrive client passwords under Settings → Security → App & device access.
- For each LightDrive client password, review its selected Email, Contacts, and/or Calendars access and revoke credentials you no longer use.
A LightDrive client password is separately revocable and limited to the Email, Contacts, and/or Calendars services selected when it was created. It does not grant Files access. Your main LightDrive password and Vault app passwords can authenticate compatible Files and Calendar clients, but not external Email or CardDAV Contacts.
If you forgot the password
Use Forgot password? on the sign-in page. LightDrive sends recovery instructions to the verified recovery email address.
