Convert tdata to Telethon

This example will show you how to initialize a TelegramClient from tdata.

Preparing

• You need to have a tdata folder which is already authorized (have at least one logged-in account).
• The default path to tdata folder on Windows is located at %appdata%\Telegram Desktop\tdata.
• We need to import these things:

  from opentele.td import TDesktop
  from opentele.tl import TelegramClient
  from opentele.api import API, UseCurrentSession, CreateNewSession
  import asyncio
  

• And we need to put the main code inside an async function:

  async def main():
      # PUT EXAMPLE CODE HERE
  
  asyncio.run(main())
  

Initialize TDesktop from tdata folder

• First we need to load the tdata folder into a TDesktop object:

  # Load TDesktop client from tdata folder
  tdataFolder = r"C:\Users\<username>\AppData\Roaming\Telegram Desktop\tdata"
  tdesk = TDesktop(tdataFolder)
  
  # Check if we have loaded any accounts
  assert tdesk.isLoaded()
  

Converting TDesktop to TelegramClient

There are two ways we can do this, either by using the current session, or create (log in to) a new session.

• Use the current session:

  # flag=UseCurrentSession
  #
  # Convert TDesktop to Telethon using the current session.
  client = await tdesk.ToTelethon(session="telethon.session", flag=UseCurrentSession)
  

• Create a new session:

  # flag=CreateNewSession
  #
  # Convert TDesktop to Telethon by creating a new session.
  # CreateNewSession will use the current session (in tdata folder) to authorize a new session using QR Login.
  # If 2FA is enabled for this account, you must specify the password via the password argument.
  # This is of course slower than UseCurrentSession.
  client = await tdesk.ToTelethon(session="telethon.session", flag=CreateNewSession)
  

Connect and print all logged-in sessions.

# Connect and print all logged-in sessions of this client.
# Telethon will save the session to telethon.session on creation.
await client.connect()
await client.PrintSessions()

Final result example

from opentele.td import TDesktop
from opentele.tl import TelegramClient
from opentele.api import API, UseCurrentSession
import asyncio

async def main():

    # Load TDesktop client from tdata folder
    tdataFolder = r"C:\Users\<username>\AppData\Roaming\Telegram Desktop\tdata"
    tdesk = TDesktop(tdataFolder)
    
    # Check if we have loaded any accounts
    assert tdesk.isLoaded()

    # flag=UseCurrentSession
    #
    # Convert TDesktop to Telethon using the current session.
    client = await tdesk.ToTelethon(session="telethon.session", flag=UseCurrentSession)
    
    # Connect and print all logged-in sessions of this client.
    # Telethon will save the session to telethon.session on creation.
    await client.connect()
    await client.PrintSessions()

asyncio.run(main())
