OpenRouter signs in from the browser
Connect OpenRouter by approving Bandicot on its own page, with no key to copy, and sign in more OpenRouter accounts the same way.
Approve once, no key to copy
The OpenRouter tile now has Sign in with OpenRouter. Bandicot opens OpenRouter's approval page in your browser, and when you approve, the page comes straight back to this Mac and the account connects. Usage bills to your own OpenRouter credits, and you can still paste a key if you prefer.
On the OpenRouter card, Sign in another OpenRouter account adds a second account the same way, next to adding one by key. A sign-in that OpenRouter refuses ends cleanly and saves nothing.
