Session Settings

As you may probably know, Telegram allows users (and bots) having more than one session (authorizations) registered in the system at the same time.

Briefly explaining, sessions are simply new logins in your account. They can be reviewed in the settings of an official app (or by invoking GetAuthorizations with Pyrogram). They store some useful information such as the client who’s using them and from which country and IP address.

  • app_version: Pyrogram 0.13.0

  • device_model: CPython 3.7.2

  • system_version: Linux 4.15.0-23-generic

app_version = 1.2.3
device_model = PC
system_version = Linux

lang_code = it
app = Client(
