Joomla password is saved in clear text as "updates_key"

[ReLater]

Describe the bug

• Joomla 4.0.5.
• JCE 2.9.18 FREE and earlier
• Firefox 95.0.2 (64-Bit) on Win10
• Save your Joomla credentials in Firefox after login in Joomla backend (FF asks if I want to save them).
• If you have saved just 1(!) login credential for the Joomla domain.
• Go to JCE > Control Panel > Options
• The field Update Options > Update Key is prefilled by FireFox with the password of the currently logged in Joomla user.
• If you save then the JCE options the password is saved in the database unhashed. Field params of #__extension COM_JCE.
• And other users can see it afterwards by clicking on the eye button.
• Users of FREE JCE version seldomly look into the "Update Options" to clear the field before saving.

Screenshots

Additional context Question: If this is not solveable from your side: Is it a problem to enter a dummy key in that field or will I get then warnings or something on updates?

Thank you!
