When authorizing, you will have access to both regular and secure authorization. To work with secure authorization, you need to download an additional extension, after the installation of which all work sessions on your computer will pass through your home IP, which will significantly reduce the risk of possible blocking from messengers.
This tool provides more security and safety for your project. However, it is safe to work with the Chat API even with normal authorization, since we also use other mechanisms to protect your account. We issue an individual IP for each client, carry out thorough work with messengers updates and introduce a fuse system so that your account is not accidentally banned. For example, the "send queue" function creates a queue for sending messages to match the "human" speed of writing messages and not arouse suspicion on messengers.
