A simple Python file to create and save a Telegram session string.

You must install telethon to use this script:

$ sudo apt install python3-telethon

OR

$ python3 -m pip install telethon

• Go to: my.telegram.org > API development tools > creating a new app (if you don't have one).
• Choose short app name (NOTE: this is the name that will appear in the list of connected devices).
• The data you need later is: App api_id & api_hash.

• Download the file telogin.py from this repository
• Run the script:

$ python3 telogin.py

The script will ask for:

• Phone number (in international format, but it is not mandatory to put + at the beginning).
• api_id (from step 1)
• api_hash (from step 1)
• The login code received
• Two-step verification (If you have enabled it)

The script creates a json file called login.json, in the following format:

{
    "api_id": "123456789",
    "api_hash": "1234567890abcdefg",
    "session_string": "abcdefghig-klmnopqr="
}

Please note, session_string contains about 350 characters and usually ends with =

You can also see in the terminal

Signed in successfully as YOUR_NAME; remember to not break the ToS or you will risk an account ban!
Session string: abcdefghig-klmnopqr=

Do not disconnect SHORT_APP_NAME from the list of connected devices, this will cause the user to no longer be able to connect with the created string, it will be necessary to create a new one.
