Username & Password Authentication System Using Python

Password authentication system is a system that is used for the identification of a user

To create a password authentication system using Python use these approaches:

import getpass
database = {"Onkar": "123456", "Modi": "654321"}
username = input("Enter Your Username : ")
password = getpass.getpass("Enter Your Password : ")
for i in database.keys():
if username == i:
while password != database.get(i):
password = getpass.getpass("Enter Your Password Again : ")
break
print("Verified")

Another Way :

count = 0
while True:
userName = input("Hello! Welcome to FaceSnap! \n\nUsername: ")
password = input("Password: ")
count += 1
if count == 1:
#tells user bye
break #exit
else:
if userName == 'Modiji' and password == '123456':
#let them in
print("You are Good to go!")
break #they are in, exit loop
else:
print("Wrong! Try Again!");

Another Way:

attempts=0
while attempts<1:
username=input('username?')
password=input('password?')
if username=='Onkar'and password=='12345':
print('you are in!')
else:
attempts+=1
print('incorrect!')
if attempts==1:
print('too many attempts')
