# Sign in

The Application can be used by any cashier when the subheading of the `Sign in` screen does not contain indication that the device needs to be setup (or that the device is locked or disabled).

To sign in to the Application, enter the cashier's `Username` and `Password`.

{% hint style="warning" %}

1. When entering the password, please note that it is sensitive to upper and lower case.
2. If this is a Cashier's first login to the Application, then the default Password is equal to the Login (case sensitive) that was set in the Merchant's Web portal.
   {% endhint %}

{% hint style="danger" %}
You have 5 attempts to enter the correct Username/password, after which the account can be locked (in this case, the Application will display a message with the number 203). The cashier's account is unlocked in the Merchant's web portal. In this case, you should contact the employee who has access to it.
{% endhint %}

{% hint style="warning" %}
If the Application displays, when trying to enter, a message with the number 101 and the text that the login and password were entered incorrectly, then the device must be transferred to the Main cashier in order for the device initialization by entering Main cashier login and password.
{% endhint %}

Upon successful sign in, the Application will display the Amount entry screen.

## 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://docs.tapxphone.com/guide/app-guide/sign-in.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.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
