anyone know why my code says authentication was accepted but it doesnt break out of the loop?

my code for reference:

import json
import random
import time

def load_accounts():
    with open("accounts.json", "r") as json_file:
        data = json.load(json_file) # Opens json file as data
        return data["users"]
    
def authenticate():
    users = load_accounts()
    if not users:
        print("Error loading accounts.")
        return False
    
    username_input = input("Username: ") # Gets username input

    for user in users: #Iterates through each of the values in the 'users' list
        if username_input == user.get("name"): # Checks if inputted username is in that iteration
            password_input = input("Password: ") # If it is it asks for the password
            if password_input == user.get("password"): # Checks if the password matches the one in the json file
                print("Authentication successful.")
                return True
            else:
                print("Invalid password. Retry.") # Wrong password prints this
                return False
    else:
        print("Invalid username. Retry.") # Wrong username prints this
        return False

def select_song():
    with open('songs.json') as songs_file:
        songs = json.load(songs_file)

    random_song = random.choice(songs)
    return random_song

def play_game():
    if authenticate():
        time.sleep(1)
        print("Let's play the game.")
    else:
        print("Authentication failed.")

def main():
    play_game()

authenticate() # Runs function
main() # Runs function
