-

-2. Create a new OAuth App

-
-### Facebook
-1. Go to [Facebook Developers](https://developers.facebook.com/)
-2. Create a new app
-3. Add Facebook Login product
-4. Configure Valid OAuth redirect URIs: `https://yourdomain.com/oauth/facebook/callback`
-
-### X (Twitter)
-1. Go to [Twitter Developer Portal](https://developer.twitter.com/)

-
-### Telegram

-2. Use `/newbot` command and follow instructions
-3. Get your bot token
-4. Configure domain settings with `/setdomain` command

-4. Select required permissions: `login:email login:info`
-
-## Email Handling
-
-Some providers (X, Telegram) don't provide email addresses. In these cases:
-- A temporary email is generated: `{provider}_{user_id}@oauth.local`
-- Users can update their email in profile settings later
-- `email_verified` is set to `false` for generated emails
-
-## Usage in Frontend
-
-OAuth URLs:
-```
-/oauth/google
-/oauth/github
-/oauth/facebook
-/oauth/x
-/oauth/telegram
-/oauth/vk
-/oauth/yandex
-```
-
-Each provider accepts a `state` parameter for CSRF protection and a `redirect_uri` for post-authentication redirects.
-
-## Security Notes
-
-- All OAuth flows use PKCE (Proof Key for Code Exchange) for additional security
-- State parameters are stored in Redis with 10-minute TTL
-- OAuth sessions are one-time use only
-- Failed authentications are logged for monitoring
