Good afternoon, I have a code for a simple username check:

@app.route('/')
def index():
    return render_template('index.html')

@app.route('/submit', methods = ['POST'])
def post():
    if request.form.get('login') == 'admin':
        return jsonify({'type':'success','msg':'success'})
    return jsonify({'type':'error','msg':'error'})

HTML:

<!DOCTYPE html>
<html>
<head>
  <title>Bot</title>
  <script src="https://code.jquery.com/jquery-3.4.1.min.js"></script>
</head>
<body>
  <div id="content">
    <form action="/submit" method="POST">
      <input type="text" name="login">
    </form>
    <button id="submit">Submit</button>
  </div>
  <script type="text/javascript">
    $('#submit').click(function(){
      event.preventDefault();
      var method = $('form').attr('method')
      var data = $('form').serialize();
      var action = $('form').attr('action')
      $.ajax({
        method: method,
        url: action,
        data: data,
        success: function(result){
          var msg = JSON.stringify(result);
          alert(msg)
        }
      })
    })
  </script>	
</body>
</html>

So, I need to implement authorization so that when I log in, the authorization page is inactive, while other pages are active.
Will there be simple examples or some advice?

from flask import session


@app.route('/')
def index():
    if not session.get('logged_in'):
        return redirect('/submit')
    else:
        return render_template('index.html')


@app.route('/submit', methods = ['POST'])
def post():
    if request.form.get('login') == 'admin':
        session['logged_in'] = True
        return jsonify({'type':'success','msg':'success'})
    return jsonify({'type':'error','msg':'error'})
