CAPTCHA Services

Japanese CAPTCHA services tell real visitors apart from automated bots that try to break into accounts, post spam, or flood sign-up forms. They guard login pages and other forms using puzzle challenges, image recognition, and behavioral checks that decide when someone needs to prove they are human.

Approaches range from hosted services you drop in with a snippet of code to plugins that secure a specific platform, so teams can match the tool to how their site is built.

Fingerprint or face recognition lets people sign in without a password, using the sensors already built into their phones for a faster, harder-to-steal login.

Protection installs straight from the WordPress dashboard, adding login and form security without touching server settings.
