How can I add one checkbox in login screen, we are not allowing the user to signup we only used to log in, and we are using a universal login page in our wordpress website. How can we implement a checkbox for terms and conditions during login? Note: We are not using signup functionality.
Unfortunately, Lock library only offers so many customizations. The terms and conditions are only available on signup as of now. You can view the options here: https://github.com/auth0/lock/blob/master/src/i18n/en.js
If this is something you need, you should consider using a custom ui login/signup page
