-If you have Two Factor Authorization (from now on, 2FA) enabled on your account, calling `.sign_in` will raise a `SessionPasswordNeededError`. When this happens, just `.sign_in()` again with a `password=`:
-
-```python
-import getpass
-from telethon.errors import SessionPasswordNeededError
-
-client.sign_in(phone)
-try:
-    client.sign_in(code=input('Enter code: '))
-except SessionPasswordNeededError:
-    client.sign_in(password=getpass.getpass())
-```

-## Enabling 2FA
-
-If you don't have 2FA enabled, but you would like to do so through Telethon, take as example the following code snippet:
-
-```python
-import os
-from hashlib import sha256
-from telethon.tl.functions import account
-from telethon.tl.types.account import PasswordInputSettings
-
-new_salt = client(account.GetPasswordRequest()).new_salt
-salt = new_salt + os.urandom(8)  # new random salt
-
-pw = 'secret'.encode('utf-8')  # type your new password here
-hint = 'hint'
-
-pw_salted = salt + pw + salt
-pw_hash = sha256(pw_salted).digest()
-
-result = client(account.UpdatePasswordSettingsRequest(
-    current_password_hash=salt,
-    new_settings=PasswordInputSettings(
-        new_salt=salt,
-        new_password_hash=pw_hash,
-        hint=hint
-    )
-))
-```
