TEAMMATES uses reCAPTCHA on the Recover Session Links page as a security check. It helps protect the website by blocking spam bots and abusive traffic, and only allows valid human users to pass through.
By default, the CAPTCHA widget is not shown on the page since no keys are specified in the config files.
However, this should be changed for production environments:
localhost and/or 127.0.0.1 in the CAPTCHA domains setting if you are using this for development as well.captchaSiteKey in the config.ts file.app.captcha.secretkey in the build.properties file.
