If you are currently authenticated as a host, but you forgot your host password or you would like to change it, then you won't find the reset host password link within your room. Here is a quick workaround to fix this:
Open an incognito/private window in your browser and open the room for which the host password should be changed
Go into the Settings and open any of the host settings
Now you are prompted to enter the host password. Below the input field, you find the link reset host password
Click the button and enter the e-mail of the host (the e-mail that was used to set up the room)
Open the e-mail that has been sent to you and define the new host password
-> Done! 🥳
If you don't get into your room anymore because you forgot the guest password, follow this link.
