I've created a setup page for my app. Code is below:
<block title="Enter the credentials for your app" endpoint="storage/passwords" entity="_new">
Through this code I'm able to store the password in encrypted format and I can see the passwords.conf in local folder. But whenever I'm opening the setup page again it's coming as blank and If I'm entering a new credentials it stores the new credential in passwords.conf. I want that after entering and saving the credentials whenever a user opens the setup page again it should display the saved username and password(password as *******).
