Allow users to log in with their Microsoft account

• Using a public account always runs the risk of being banned.
• Although I have received an email saying that I can use New Bing Chat, I am actually unable to use it because Microsoft has used powerful means to detect that my region is in mainland China, and I need to use very complex steps to deceive it. So users with accessible accounts also have a need to use your web proxy.

I have considered this, however, requesting users' Bing cookies appears to be a risk to the user. As Vercel limits API response time to 10 seconds, which is significantly less than the response time of the Bing AI, I had to give up the open-sourced Next.js API solution and opt for a self-hosted API, making the request for cookies seem suspicious.

Let me know if you have a good solution.
