Reset text field to default when starting Blender

Question

Is there a way of reseting a text field every time Blender is initiated, saved or before closing? I want to create a password field for an Addon and I don't want it's value to be saved alongside the blend file.

I have looked for a while but I haven't seen anyone asking this particular subject.

A little bit of code:

row.prop(scene.testing, "password")

Password being a String Property created like this:

password: StringProperty(
        name="Password",
        description="Password",
        default="",
        subtype="PASSWORD")

If it could be possible to reset to the default value which is "", that would be perfect, but I don't seem to find anything.

Thanks!

Use the window manager.

For a session variable suggest using the window manager. Will always be default when new blender is openened. No window manager property is saved directly.

bpy.types.WindowMangager.password =  StringProperty(
        name="Password",
        description="Password",
        default="",
        subtype="PASSWORD")

SKIP_SAVE

Also look at using the skip save option of a property.
