In this tutorial, we are going to make a Login System in Tkinter Python. For this project, you need to have the Tkinter module.
This small project will contain features of login and signup systems as we saw in your daily life. Using this project, you will come to know a little information about how the login systems of all websites/applications work.
You can install Tkinter Module by writing the below command in your python terminal.
pip install tkinter
We also need to create a .txt file for saving the data of the users and validating the data entered by the user. Here I have made a file named Login.txt. You can give your name as per your choice.
Login System in Tkinter Python: Complete Code
from tkinter import *
import tkinter.messagebox as tsmg
root=Tk()
def check():
a=uname.get()
b=pwd.get()
c=cpwd.get()
mix=a+"-"+b+"-"+c
// Instead of Login.txt you should write your file name.
with open("Login.txt","r") as fi:
d=fi.readlines()
if b==c:
if str(mix) in str(d):
tsmg.showinfo("Welcome",f"Hello {a}, You Have SuccessFully Logged In")
else:
tsmg.showerror("Error","No User Found, Please Sign-Up First")
else:
tsmg.showerror("Error","Both Password Are Different")
uname.set("")
pwd.set("")
cpwd.set("")
def save():
a=uname.get()
b=pwd.get()
c=cpwd.get()
mix=a+"-"+b+"-"+c
if a!="" and b!="" and c!="" :

tsmg.showerror("Error","You Already Have An Account, Please Login")
