Hi Eriny Adek
Since the sign-in window itself appears unusually small, increasing Text Size alone may not help. If this is specific to Revit/Autodesk, try right-clicking the Revit shortcut → Properties → Compatibility → Change high DPI settings → Override high DPI scaling behavior, then test System (Enhanced) rather than Application. This can help legacy or non-DPI-aware dialogs render at a more usable size on high-resolution displays.
