AppRanks verdict
Generated from live marketplace data — refreshed daily
Authorizer is a category-leading WordPress app with a limited review volume. It is listed in the Login category on WordPress Plugin Directory, which AppRanks treats as the canonical taxonomy node for ranking and competitor comparison. 20 reviews put it in the early-traction tier — useful for early-stage stores willing to be on the leading edge. Early-traction review counts are sensitive to single launch periods or feature events, so a 30-day re-check before bigger commitments often resolves whether the trend is sustained. Paid-only pricing means evaluating fit on the marketplace listing or via the developer's documentation before installing. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical WordPress Plugin Directory listing.

How Authorizer works
Authorizer restricts access to a WordPress site to specific users, typically students enrolled in a university course. It maintains a list of approved users that you can edit to determine who has access. It also replaces the default WordPress login/authorization system with one relying on an external server, such as Google, CAS, LDAP, or an OAuth2 provider. Finally, Authorizer lets you limit invalid login attempts to prevent bots from compromising your users’ accounts.
View or contribute to the plugin source on GitHub: https://github.com/uhm-coe/authorizer
Authorizer requires the following:
CAS server (2.x, 3.x, 4.x, 5.x, 6.x, or 7.x) or LDAP server (plugin needs the URL)
PHP extensions: php-ldap, php-curl, php-dom
Authorizer provides the following options:
Authentication: WordPress accounts; Google accounts; CAS accounts; LDAP accounts; OAuth2 accounts
Login Access: All authenticated users (all local and all external can log in); Only specific users (all local and approved external users can log in)
View Access: Everyone (open access); Only logged in users
Limit Login Attempts: Progressively increase the amount of time required between invalid login attempts.
Shortcode: Use the [authorizer_login_form] shortcode to embed a wp_login_form() outside of wp-login.php.
