+## CAPTCHA Solving
+Passes uses reCAPTCHA v3 Enterprise to protect against bots on their login page. The default method to solve this CAPTCHA is to use a Playwright browser to automatically solve it. If you don't want to use this method or it doesn't work for you, you can also use a CAPTCHA solving service by providing the API domain and API key in the `config.toml` file.

+### Supported Services
+- [CapSolver](https://www.capsolver.com/) (api.capsolver.com)
+- [AntiCaptcha](https://anti-captcha.com/) (api.anti-captcha.com)
+
+2Captcha and CapMonster were also tested and did not work for this website, so support for these services was not added.
