Hi @dreamlove

As far as I know, Captcha is a not required to access your admin side. You can still access your studio even with this Captcha issue in the frontend through this url: https://www[dot]yoursite[dot]com/studio

You are probably having this problem because you entered the wrong reCaptcha (from Google) public and private/secret key or you entered the ones from the hCaptcha (a reCaptcha alternative) while you set your UNA system to use reCaptcha or vice versa. I once made the same mistake. Please see: https://una.io/d/hcaptcha-not-working-in-una-13-b3

Which UNA version are you running? In any version previous to B4, Captcha settings are found in Studio > Settings > Site Security and in Studio > Developer. (You also need to select which Captcha to use in the Developer App)

From UNA B4, all the Captcha settings were moved to one place: Studio >Settings > Site Security.

Now, to answer your question on how to disable the captcha from the database, I can see that you meant the one on the Forgot Password page as shown on the screeshot, right? Please access your database, go to:

'sys_form_display_inputs' table > sys_forgot_password, then change the value of 'Active' from 1 to 0 (zero) to disable the captcha.

Regards.
