# About message signing(Yoroi Mobile)

Message signing allows you to cryptographically sign a message using your wallet address and later verify that signature. This is commonly used to prove address ownership without sending a transaction.
### Which message formats are supported?
Yoroi supports signing and verifying the following message types:
* **Plain text**
* **JSON**
* **Hexadecimal (hex)**
### Where can I find the Message Signing feature?
You can access it from the **Menu > Message signing **in the bottom navigation bar.
> **Note:** Message Signing is currently **not available** on the Yoroi Browser Extension.
### How do I sign a message?
1. Open the **Sign** tab.
2. Your wallet **address is automatically displayed**.
3. Enter any arbitrary message in the input field.
4. Tap **Sign** to generate a signature.
Once signed, you can **copy**:
* The **signature**
* The **key**
* The **public key (pubkey)**
