How to write authorization in Telegram bot in Python?

Question

Python

There is a bot written in Python 3.7 using the pyTelegramBotApi 3.6.6 library.
The bot is configured to retrieve information from the database, but since access to the bot can be obtained by anyone who recognizes his name, the question of authorization becomes. Actually, how can I use this library to issue authorization by user ID?
PS I apologize for possible spelling / punctuation errors, yes, the school is our everything ...

Answer 1

As far as I remember, by means of the library in any way.
I advise you to start any database (or a local file) and write user IDs into it and whether it is authorized ....
About authorization methods, it's just complete fantasy. From a password to complex certificates.
