How can I protect my user’s passwords in app by hiding their password character inputs
Glide does not support password based authentication - what are you using passwords for?
In app function that would require a password but if not possible then how can i make sure that the placeholder stays empty every they are to use the screen not keeping their past data as placeholder
If you are requiring a password, then you are probably approaching it the wrong way.
You should be able to grant/revoke access to screens and/or functionality based on the signed in user identity.
The problem with trying to use passwords is that there is no way to keep them secure, so as soon as you try you have created a security hole ready to be exploited.
I’d recommend reviewing the Glide Docs on Security and User Data.
