Thanks for reaching out to Jotform Support. I'm not sure if I understood your question correctly.Do you want to set a password for your account? If so, you can assign a password to your account by resetting Jotform Account Password
On the other hand, if you want to password-protect your forms then please review a step-by-step guide on How to Password Protect a Form
But, if you were referring to something else, can you explain it a bit more so we can help you with it?
Keep us updated and let us know if you need any more help.
