Answer 1

Gouri Shinde if I understand correctly then you forgot adding x +=1 if usr or pwd is wrong

Answer 2

Gouri Shinde if you use a while loop on a button function the loop will be infinite, thats because the function is called only when you press the button, so all you need to do is check how much times the log in button was pressed, also you used the same function for both cancel and log in button.
I also recommend using app.clearAllEntries so the user doesnt have to type everything again

from appJar import gui

tries = 0
def log(button):
global tries
usr = app.getEntry("Username")
pwd = app.getEntry("Password")

if usr == "user" and pwd == "pass":
print("Access granted.", "You are now logged in !")
app.infoBox("Logged in", "You are now logged in !")

elif usr != "user" or pwd != "pass":
print("Access denied", "Your credentials are invalid !")
app.errorBox("Error", "Your credentials are invalid !")
app.clearAllEntries(callFunction = False)
tries += 1

if tries == 3:
print("No more attempts", "try again later !")
app.infoBox("no more attmpt", "try again later !")
app.stop()

def cancel(button):
app.stop()

app = gui("LOGIN WINDOW")
app.setBg("white")
app.setFont(18)

app.addLabel("title","Login")
app.setLabelBg("title","orange")
app.setLabelFg("title","blue")

app.addLabelEntry("Username")
app.addLabelSecretEntry("Password")

app.addButtons(["Log In", "Cancel"], [log, cancel])

app.setFocus("Username")

app.go()
