When we log in with 2-factor authentication every time we must get the authentication code. Maybe it is an idea to ask ones a month and not everytime we login.

Hi Ronald,
The 2-factor authentication is intended to only allow access when you know something (password) and you have something (e-mail account, phone, totp device).
When you allow leniency when it comes to ‘having something’ for a month, you also allow the attacker who knows your password access for a month. After submitting a correct 2FA authentication after the month has passed, you'd grant the attacker access for another month as well.
