You need to set a variable for your while loop and change the bottom if statement. You then need to count to the variable each iteration. Also, you should take the name input and first print statement out of the loop so not to have it repeat each time.
print ("Welcome to yor account creation")
name =input('Enter your name: ')
n = 0 #add a variable set to 0
while n != 3: #include variable in while statement
pasw =input('Enter your password: ')
paswr =input('Re-enter your password: ')
if pasw == paswr:
print ("Your account has been created")
break
if pasw != paswr:
print ("Please re-enter information")
n += 1 #add 1 each iteration
if n == 3: #if 3 iterations run print and break
print ("Too many incorrect tries, your account has not been created")
break
