Allow multiple accounts

[LoHub]

Use Case:
I have several OSM accounts that I use depending on my location. I created
this because I think it's too easy to track someone based on their contributions.

The problem is, it's difficult for me to switch accounts every time.

Proposed Solution:

I suggest that SCEE allow users to manage multiple accounts and make it easier to switch between them.

Thanks for this powerful tool, it really makes it simple to contribute daily!
