# Authentiction with Gmail

## Step 1: Obtain Password 

If you choose to register to Opentact with your Gmail account, Opentact will send you an email with your password.  Here is how the email looks like:

## Step 2: Generate Base64 Key

Next, you will take your gmail and password above to generate a base64 key using the following command in Linux:

```
echo -n 'testuser@gmail.com:18aec2c0-1e9c-48d9-b7a2-363063a153ff' | base64 

```

You should obtain from the above command a token like this:

```
dGVzdHVzZXJAZ21haWwuY29tOjE4YWVjMmMwLTFlOWMtNDhkOS1iN2EyLTM2MzA2M2ExNTNmZg==
```

> You can revert the token with the following command:
>
> echo -n 'dGVzdHVzZXJAZ21haWwuY29tOjE4YWVjMmMwLTFlOWMtNDhkOS1iN2EyLTM2MzA2M2ExNTNmZg==' | base64 -d
>
> <testuser@gmail.com>:18aec2c0-1e9c-48d9-b7a2-363063a153ff%

## Step 3: Generate API Token

You can use the following command to generate API token which you can use to execute Openatct APIs:

{% code overflow="wrap" %}

```
curl https://api.opentact.org/rest/auth --header 'Authorization: Basic aW5oZXJpdGVkYXJ0c0BnbWFpbC5jb206MThhZWMyYzAtMWU5Yy00OGQ5LWI3YTItMzYzMDYzYTE1M2Zm'
```

{% endcode %}

Here is an example output:

{% code overflow="wrap" %}

```
{

  "payload": {

    }
  }
}// Some code
```

{% endcode %}

&#x20;The token you used above can be used for executing Opentact API.

{% code overflow="wrap" %}

```
"token": "eyJhbGciOiJIUzR5cCI6IkpXVCJ9.eyJ1dWlkIjoiNDUyMWY5Ny00NzU1LWJlOTktZGFjYzE4OTJhYmI0Iiwicm9sZSI6IkFkbWluIiwiZG9tYWluIjoib3BlbnRhY3Qub3JnIiwixNzA5NTM0OTc1LCJleHA2MjEzNzQeUPpllWBc7hyvpt063VuVJMOeFPFmbFq4k",// Some code
