GitHub's two-factor authentication has a significant flaw; am able to add 7 digit random digit , it should have a max length of 6

Expected Behavior
it should only accept 6 digit

Current Behavior
its accepting 7 digit ( i tried multiple times)

Possible Solution
simple textbox limit

Start by locating the browser-side two-factor authentication textbox and checking how its input is currently validated. Confirm the behavior with six- and seven-digit values, then ensure the field accepts six digits but rejects longer input and add or update the relevant validation coverage if the project provides it.
