# Authentication It's possible to configure authentication using a third party Authentication Provider (referred to as AP). Currently only Telegram is supported as an AP. ## Telegram In order to use Telegram as an AP you need to be hosting Owltide under a domain name over https, using http will not work. You will also need a bot which can be created by messaging [@BotFather](https://t.me/BotFather), with the domain of the bot set using the `/setdomain` command to the domain Owltide is hosted under. Once you have the pre-requisites you need to configure `NUXT_TELEGRAM_BOT_TOKEN_FILE` to a path to a file containing the token of the bot with no spaces or new-lines. `NUXT_PUBLIC_TELEGRAM_BOT_USERNAME` to the username of the bot. And finally `NUXT_PUBLIC_AUTH_TELEGRAM_ENABLED` to `true` to enable authentication via Telegram.
