Cloud / Password sync

**Is your feature request related to a problem? Please describe.**
A problem that I have is that I have a lot of tasks on my home pc but when i want to use my laptop, it doesn't transfer over.

**Describe the solution you'd like**
A good way to solve this is to create a cloud service or integration with google drive desktop, onedrive etc.

A cloud service would (realistically) be expensive to manage, so the next best thing is to use an integration with onedrive or google drive, where the user would do --sync auth to authenticate themself using oauth and if the program terminates, it will sync automatically and be sent towards their devices.

**Additional context**
Add any other context or screenshots about the feature request here.
No, however it is a pretty nifty feature that people will appreciate.

No source files, tests, or entry points are identified in the issue. First clarify the target provider or providers, OAuth flow, conflict behavior, and sync timing; done should be defined as authenticated task transfer between devices with automatic synchronization.
