I can't turn off the meeting password.

Hi @shemira welcome to the community! Can you please share what exact settings you've enabled/disabled from https://zoom.us/profile/setting 

You have the following passcode options of enabling/disabling which maybe affecting your inability to turn off meeting passcode when scheduling a meeting (PMI/Random Generated MeetingID) or starting an instant meeting.

• Require that all meetings are secured with one security option
• Require a passcode when scheduling new meetings
• Require a passcode for instant meetings
• Require a passcode for Personal Meeting ID (PMI)

I am having this same problem, I am the owner and the admin and under Profile Meeting Settings it says "locked by admin" next to the toggle for Meeting Passcodes. 

I am having the same issue. I am ready to cancel this

yup zoom sucks

Hi ​@shemira 
I hope you are doing well, the reason it won’t toggle is almost always a locked account or group setting site above your meeting level control. sign in at zoom.us.Go to account management >account setting .Find the passcode options under security section and look for a lock icon next to them if, its locked there that’s what’s greying out your toggle.
