How to set the default value to custom fields (checkbox to be checked)

[jardob]

Hello, I have created a checkbox in the account details, with which I turn on one additional widget on the main page. This works for me. I originally wanted the checkbox to be checked, but I couldn't figure this out. Can someone advise me how to do it (if possible). I don't want to do it manually by writing to the database. I would prefer if it could be set somehow in the admin panel or in the template. This would solve both old and new users.
Thanks in advance for the advice.
