Is it secure to set the cookie to sameSite: "none"?

[maiieul]

In pages/api/auth/[...nextauth].ts, you have set sameSite to "none":

export const authOptions: NextAuthOptions = {
  providers: [
    GithubProvider({
      clientId: process.env.GITHUB_ID,
      clientSecret: process.env.GITHUB_SECRET,
    }),
  ],
  cookies: {
    sessionToken: {
      name: `${useSecureCookies ? "__Secure-" : ""}next-auth.session-token`,
      options: {
        httpOnly: true,
        sameSite: "none",
        path: "/",
        domain: `.next-auth-capacitor.vercel.app`,
        secure: useSecureCookies,
      },
    },
  },
  theme: {
    colorScheme: "light",
  },
};

Couldn't this lead to security issues?
