[Tkinter] password with Entry widget

[Yoriz]

Creating GUI code is easier if you use classes.
Here is an example of your code turned into a class.

import tkinter as tk


class Main:
    def __init__(self, root):
        self.root = root
        self.rightpassword = "tarek"
        self.nb_attempt = 0
        self.attempt_limit = 3
        self.attempt_authorized = True

        root.title("Access Application")
        root.geometry("1400x480")
        # root.configure(bg = "#eaeaea")

        # Add Title1
        lblTitle1 = tk.Label(root, text="Gestion des accès", font=(
            "Arial", 21), bg="darkblue", fg="white")
        lblTitle1.place(x=50, y=0, width=300)

        # password area
        lbpassword = tk.Label(root, text="Password :", font=(
            "Arial", 21), bg="darkblue", fg="white")
        lbpassword.place(x=450, y=200, width=300)
        entrypassword = tk.Entry(root, font=("Arial", 21))
        entrypassword.bind("<Return>", self.entrypassword_return_event)
        entrypassword.place(x=780, y=200, width=300)
        self.entrypassword = entrypassword

        lbcomment = tk.Label(root, text="Comment :", font=(
            "Arial", 21), bg="black", fg="white")
        lbcomment.place(x=180, y=250, width=250)
        entrycomment = tk.Entry(root, font=("Arial", 21), bg="white", fg="red")
        entrycomment.place(x=450, y=250, width=800)
        self.entrycomment = entrycomment

    def entrypassword_return_event(self, event):
        word = self.entrypassword.get()
        if word != self.rightpassword:
            self.authorization_attempt()
        else:
            self.update_entry_comment("Congratulation Access authorized")
            self.authorized_code()

    def authorization_attempt(self):
        self.nb_attempt += 1
        if self.nb_attempt < self.attempt_limit:
            self.attempt_authorized = True
            self.update_entry_comment((
                "Try again, remaining attempts : "
                f"{self.attempt_limit-self.nb_attempt}"))
        else:
            self.attempt_authorized = False
            self.update_entry_comment("Access denied, out of trys")
            self.root.after(3000, self.root.quit)

    def update_entry_comment(self, comment):
        self.entrycomment.delete(0, tk.END)
        self.entrycomment.insert(0, comment)

    def authorized_code(self):
        print('add authorized code here')


root = tk.Tk()
Main(root)
