Nextend Social Login Pro registers each connected provider (Facebook, Google, Twitter, Apple, LinkedIn, and more) on a per-user basis and persists the link inside wp_usermeta with provider-specific keys such as nsl_facebook_id, nsl_google_id, and nsl_apple_id. The settings screen lists providers and stats, but there is no single grid that answers 'which users are linked to which providers right now'.

SleekView reads wp_users and joins the matching wp_usermeta rows for every provider Nextend supports. Each user row exposes one column per provider plus a meta column for the link timestamp and the last-login date. Filters like 'users linked only to Facebook' or 'users with no social provider linked' become first-class chips, useful for migration plans and provider deprecation work.

Edits route through Nextend's own unlink handler when removing a provider link, so the plugin's internal counters and any related caches stay in sync. Direct meta edits are available behind an admin override for cases like manually relinking after a Facebook ID rotation, with a clear warning that the operation bypasses the plugin's verification path.

Social login is the kind of feature that quietly accumulates state across thousands of users without anyone noticing. Every successful login through Nextend writes a row to wp_usermeta that maps a user to a provider, and over years those rows accumulate into a real identity graph. The plugin's own admin focuses on configuration (which providers are enabled, what the buttons look like) and aggregate stats, which is right for setup but wrong for operations.

Identity teams plan provider sunsets and need to know exactly how many users would be locked out. Compliance teams answer questionnaires about which third-party identity providers carry user data. Support agents need to see at a glance whether a stuck user has a provider linked or whether they need a password reset path.

SleekView turns the usermeta key space into a normal grid, with one row per user and one column per provider, and the operational questions become easy. The data was there all along; the view is what makes it answerable.
