Is there an way to login to a user on the server side without sending the token to the client?

[Gonzman]

Hi,
is there an way to login to a user on the server side without sending the token to the client?
Because I have a form for unlogged in user and if they submit the form and the sever insert the data the user gets a jwt token.
I added useSsrCookies: false to the Nuxt.config.ts and it didn't worked.

Best regards.

If you're asking to be able to "impersonate" a login as another user, this is how I do it.

I first guard so admins can't be impersonated, and admins are defined via user_metadata.role
user.user_metadata?.role === 'admin'

I have another callback page for impersonation specifically to give more details as the process takes a little longer as it's more calls.

const redirectUrl = import.meta.dev
      ? 'http://localhost:3000/admin/impersonate-callback'
      : `${config.public.siteUrl || config.public.supabase.url}/admin/impersonate-callback`;

Then I create a magic link. You likely need that auth method enabled. I would assume so, but I never tried with it off.

const { data: linkData, error: linkError } = await serviceRole.auth.admin.generateLink({
      type: 'magiclink',
      email: targetUser.user.email!,
      options: {
        redirectTo: redirectUrl,
      },
    });

I also return the data from the api to complete the call

return {
      success: true,
      magicLink: linkData.properties?.action_link,
      targetUser: {
        id: targetUser.user.id,
        email: targetUser.user.email,
        full_name: targetUser.user.user_metadata?.full_name,
      },
      adminUserId: adminUser.id,
    };

That's essentially it.
