Setup Master Password Dialog
If your master password is not set yet, you can open this dialog by clicking Master Password on the Passwords page. In certain circumstances, this dialog may also open automatically.
Specify the password that you want to be set as your master password. ( The master password is used to access the PhpStorm password database where - if so specified - your passwords are stored. Instead of the individual passwords, you'll be able to use your master password.)
You can set the password empty. As a result, PhpStorm won't ask you for the password when accessing the password database. However, the security of your passwords in that case will be lower.
