__Host-next-auth.csrf-token	dermsquared.com		Session
The __Host-next-auth.csrf-token cookie is used by the Next.js authentication library for cross-site request forgery (CSRF) protection. The __Host- prefix indicates that the cookie is only accessible over a secure HTTPS connection, and can only be set on a domain that has been registered as a secure site using the HSTS (HTTP Strict Transport Security) policy. The csrf-token value in the cookie is used by the Next.js framework to verify that requests made to the server are legitimate and were made by the same user that initiated the request. This helps prevent attackers from impersonating users and making unauthorized requests. The csrf-token cookie is typically set when a user logs in or signs up for a site that uses Next.js authentication. The cookie is then included in subsequent requests made by the user to the site's API, ensuring that each request is authorized and secure.
__Secure-next-auth.callback-url	dermsquared.com		Session
The __Secure-next-auth.callback-url cookie is set by the NextAuth.js library when using a secure HTTPS connection.

It contains a unique identifier that is used to lookup the user's session data on the server.

The cookie typically expires when the user logs out or closes their browser.
