## Activating a User

User activation is very easy with Sentry, you need to first find the user you
want to activate, then use the `attemptActivation()` method and provide the
activation code, if the activation passes it will return `true` otherwise, it
will return `false` .

If the user you are trying to activate, is already activated, an Exception
`Cartalyst\Sentry\Users\UserAlreadyActivatedException` will be thrown.

### Exceptions {#exceptions}

**Cartalyst\Sentry\Users\UserAlreadyActivatedException**

If the provided user is already activated, this exception will be thrown.

**Cartalyst\Sentry\Users\UserNotFoundException**

		$user = Sentry::findUserById(1);

		// Attempt to activate the user

		{

		else
