Login field showing as plain text

Hello, just a quick question regarding the login screens and hopefully someone can help me with this.

The password field is currently showing plain text only, is this an issue on my end? If not, is there any way to make it hidden like a normal password field? Even though I might not be creating an app that needs to be super secure, it's bound to turn people off having their passwords showing as plain text.

If this isn't possible, are there any alternatives? There will be content that needs to be kept away from public view. IE. Shift information for employees

Thanks!
