Thank you for your contribution, yet it cannot be approved because it does not follow the Utopian Rules.

• The title of your contribution is misleading. You are talking about validations on text fields, not user authentication.
• You mentioned several items that the user will learn, yet they are not discussed in the tutorial, such as back end validation.
• Your examples are not well explanatory, and you do not explicitly show nor highlight properly how and where the code will be changed, not give exact samples of how the code will eventually function and look.
  Please keep these notes in mind when writing your next tutorials.
