How to enable two-step verification on Telegram and enhance your account security on the messaging app insider@insider.com (Dave Johnson) Telegram is a group messaging app that, by default, has no login step. If you prefer, you can add a password as part of the app's two-step verification. To enable two-step verification on Telegram, go to the app's Privacy and Security settings and follow its prompts. Telegram is a messaging app that has grown in popularity in recent months, partly for its privacy and encryption features and its support for large group chats. When you first set up Telegram, it only asks for your phone number and then verifies it using a text message. But otherwise, there is no login or security. However, you can enhance Telegram's security with two-step verification.
