Mysterious brave wallet and sync

[mrssmith]

I have some questions about the brave browser.

A password form sometimes appears. But what is this?
Not my metamask password, not my brave wallet password, then, what is this?
How can I unlock this mysterious wallet? and how can I use it? and what is it for?

About the connection with an receiving wallet for brave rewards, how can I set up same wallet between multiple PC’s brave?
I set on PC-A and then PC-B, but it dis-connected on PC-A.
(I live in Japan)

How can I sync the brave wallet on many devices such as PC-A, PC-B, iPhone, Android?
I want to use only one wallet.
(I have already synced the multiple brave device. I mean, historical data and bookmark and app)
If I can set this up, I think I can set “Question 2” up.

I may be using different wallet on PC-A and PC-B.
(They are at the different house each, so I cannot confirm now.)
But in this situation, and if I can set up same wallet on multiple device, what will the brave rewards which I had already gotten be?

Hope your reply soon.
Best

Thank you for your reply.

Yes, but it is my PC-B screenshot.
When I verify my wallet for brave rewards on PC-B, the verification of PC-A was terminated.
How can I connect and verify only one wallet for my brave rewards?
and, how can I use same brave rewards for multiple device?
Please tell me how to set up.

Hope your reply soon.
