|
|
Starts the client (connects and logs in if necessary).
|
|
|
|
By default, this method will be interactive (asking for
|
|
user input if needed), and will handle 2FA if enabled too.
|
|
|
|
If the event loop is already running, this method returns a
|
|
coroutine that you should await on your own code; otherwise
|
|
the loop is ran until said coroutine completes.
|
|
|
|
Arguments
|
|
phone (`str` | `int` | `callable`):
|
|
The phone (or callable without arguments to get it)
|
|
to which the code will be sent. If a bot-token-like
|
|
string is given, it will be used as such instead.
|
|
The argument may be a coroutine.
|
|
|
|
password (`str`, `callable`, optional):
|
|
The password for 2 Factor Authentication (2FA).
|
|
This is only required if it is enabled in your account.
|
|
The argument may be a coroutine.
|
|
|
|
bot_token (`str`):
|
|
Bot Token obtained by `@BotFather <https://t.me/BotFather>`_
|
|
to log in as a bot. Cannot be specified with ``phone`` (only
|
|
one of either allowed).
|
|
|
|
force_sms (`bool`, optional):
|
|
Whether to force sending the code request as SMS.
|
|
This only makes sense when signing in with a `phone`.
|
|
|
|
code_callback (`callable`, optional):
|
|
A callable that will be used to retrieve the Telegram
|
|
login code. Defaults to `input()`.
|
|
The argument may be a coroutine.
|
|
|
|
first_name (`str`, optional):
|
|
The first name to be used if signing up. This has no
|
|
effect if the account already exists and you sign in.
|
|
|
|
last_name (`str`, optional):
|
|
Similar to the first name, but for the last. Optional.
|
|
|
|
max_attempts (`int`, optional):
|
|
How many times the code/password callback should be
|
|
retried or switching between signing in and signing up.
|
|
|
|
Returns
|
|
This `TelegramClient`, so initialization
|
|
can be chained with ``.start()``.

|
|
Changes the 2FA settings of the logged in user.
|
|
|
|
Review carefully the parameter explanations before using this method.
|
|
|
|
Note that this method may be *incredibly* slow depending on the
|
|
prime numbers that must be used during the process to make sure
|
|
that everything is safe.
|
|
|
|
Has no effect if both current and new password are omitted.
|
|
|
|
Arguments
|
|
current_password (`str`, optional):
|
|
The current password, to authorize changing to ``new_password``.
|
|
Must be set if changing existing 2FA settings.
|
|
Must **not** be set if 2FA is currently disabled.
|
|
Passing this by itself will remove 2FA (if correct).
|
|
|
|
new_password (`str`, optional):
|
|
The password to set as 2FA.
|
|
If 2FA was already enabled, ``current_password`` **must** be set.
|
|
Leaving this blank or `None` will remove the password.
|
|
|
|
hint (`str`, optional):
|
|
Hint to be displayed by Telegram when it asks for 2FA.
|
|
Leaving unspecified is highly discouraged.
|
|
Has no effect if ``new_password`` is not set.
|
|
|
|
email (`str`, optional):
|
|
Recovery and verification email. If present, you must also
|
|
set `email_code_callback`, else it raises ``ValueError``.
|
|
|
|
email_code_callback (`callable`, optional):
|
|
If an email is provided, a callback that returns the code sent
|
|
to it must also be set. This callback may be asynchronous.
|
|
It should return a string with the code. The length of the
|
|
code will be passed to the callback as an input parameter.
|
|
|
|
If the callback returns an invalid code, it will raise
|
|
``CodeInvalidError``.
|
|
|
|
Returns
|
|
`True` if successful, `False` otherwise.
