# Signing a Message Using Freewallet

Freewallet lets you manually sign messages with your address. <mark style="color:yellow;">This function can also be done when Freewallet is entirely offline.</mark>\
\
Signing a message is done offline and <mark style="color:yellow;">is not broadcasted to the blockchain</mark>.&#x20;

This is most commonly <mark style="color:yellow;">used to validate that you are in fact in control</mark> of your address.&#x20;

This can be used to "sign in" to websites like <https://pepe.wtf/> and other uses include the "proof of ownership" of tokens you hold on that address.&#x20;

A great example of how this sign message feature is used by creators to access the website [https://dankset.io](https://dankset.io/) can be found in this [informative video](https://www.youtube.com/watch?v=bG8SXCKrw50) made by RobotLoveCoffee.

<mark style="color:green;">This cryptographic measure to prove your identity/control over the address you sign from is a valuable tool.</mark>

<mark style="color:red;">**Signing messages are much different than**</mark> [**Signing Transactions**](/freewallet.io-user-manual/freewallet-functions/signing-a-transaction-using-freewallet.md) <mark style="color:red;">**(which are considered risky to loss of funds). It is best to correctly and thoroughly understand the difference.**</mark>

To Sign a message first navigate to the top right of Freewallet and select “Actions.” Then select the “Sign Message” button:

* You have the choice here to change the Source address of signing the message.
* Next you will input the Message into the Message field
* After you sign the message your address specific Signature will complete in the Signature field of this window, <mark style="color:yellow;">this Signature will be what you use to sign in</mark> to the websites mentioned before.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://davestaxcp.gitbook.io/freewallet.io-user-manual/freewallet-functions/signing-a-message-using-freewallet.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
