This means only you—and the people you chat with—can read them. #### ⚠ You must save your recovery key When you first log in, Element will ask you to create or confirm a **recovery key (or passphrase)**. This key is essential. 👉 **If you lose this key:** - ❌ You will lose access to your encrypted message history - ❌ Your existing chats cannot be restored - ❌ Even administrators cannot recover your data #### 🔐 Why this is intentional This is a **deliberate security design** : - Your messages are encrypted in a way that **only you can decrypt them** - The server cannot read your messages - There is **no backdoor or reset mechanism** for encrypted history 👉 This ensures **maximum privacy and full data ownership** #### 💡 Recommendation Store your recovery key securely in a password manager. Recommended: - **KeePass** → [https://keepass.info/](https://keepass.info/) You can store: - Your recovery key - Your passphrase - Backup credentials ### 🔄 Using your own domain If you are running your own instance (instead of infinito.nexus), simply replace the domain: ```auto matrix.your-domain.tld element.your-domain.tld auth.your-domain.tld ``` 👉 Example: ```auto https://matrix.example.com https://element.example.com https://auth.example.com ``` The same applies to your Matrix ID: ```auto @username:your-domain.tld ``` * * * ## 👤 Your Matrix ID (MXID) Every user has a unique Matrix ID: ```auto @username:infinito.nexus ``` ### Example ```auto @alice:infinito.nexus ``` 💡 You’ll use this ID for: - Messaging and contacts - Inviting other users - Communicating across different Matrix servers * * * ## 🔗 Useful Resources - [https://matrix.org/](https://matrix.org/) - [https://element.io/](https://element.io/) - [https://schildi.chat/](https://schildi.chat/) - [https://www.keycloak.org/](https://www.keycloak.org/)
