166-188: Consider internationalization for date formatting.

The "Last active" column implementation correctly handles edge cases (invited users and missing data). However, the date formatting uses a hardcoded "en-US" locale.

🌍 Optional: Support international date formats

Consider using the user's browser locale or a workspace-level locale preference:

           <span className="text-sm text-neutral-500">
-             {new Date(user.lastLoginAt).toLocaleDateString("en-US", {
+             {new Date(user.lastLoginAt).toLocaleDateString(undefined, {
                month: "short",
                day: "numeric",
                year: "numeric",
              })}
           </span>

Passing undefined as the locale uses the user's browser locale automatically.

24-24: LGTM!

The nullable lastLoginAt field is correctly positioned and typed. The nullable constraint is appropriate since existing users won't have login data until their next authentication.

apps/web/lib/zod/schemas/workspaces.ts (1)

216-216: LGTM!

The schema validation for lastLoginAt correctly uses z.date().nullish() which is the proper Zod 4 syntax for nullable/optional date fields.

apps/web/app/app.dub.co/(dashboard)/[slug]/(ee)/settings/members/page-client.tsx (1)

140-140: LGTM!

The column width adjustment accommodates the new "Last active" column appropriately.

apps/web/lib/auth/options.ts (1)

578-585: LGTM!

The background update to lastLoginAt is well-implemented:

• Uses waitUntil to avoid blocking the sign-in response
• Correctly placed in the events.signIn handler to capture all authentication flows
• Captures the timestamp at sign-in time with new Date()
