Use basic authentication to connect to a ServiceNow instance with the ServiceNow SDK.

## Antes de Iniciar

Role required: admin

## Por Que e Quando Desempenhar Esta Tarefa

This procedure uses the ServiceNow SDK command-line interface (CLI). From a command-line tool, enter `now-sdk --help` to get information about the available commands and global options. To get additional information about a
command and its parameters, enter the command and `--help` or `-h`. For example, `now-sdk auth --help`. For more information about the CLI, see [ServiceNow SDK CLI](https://servicenow-prod.fluidtopics.net/PRE3GTgYc~ImvC7_7y2WzA#servicenow-sdk-cli-commands "Use the ServiceNow SDK command-line interface (CLI) to manage changes between a local application and the application on an instance.").

## Procedimento

1. Open a command-line tool on your system. {#authenticate-instance-basic-auth__open-cmd}
2. Create a local directory for your application.
3. In Visual Studio Code, open the directory.
4. From the application directory, open an integrated Terminal window.
5. Specify the instance to authenticate to with the `auth` command.Specify an alias and the authentication method to use with the `auth save` command.  

       npx @servicenow/sdk auth --add <instance>

       now-sdk auth save <alias> --type basic

   To set this alias as the default alias, add the `--default` or `-d` parameter to your command.  
   For example:

       npx @servicenow/sdk auth --add https://myinstance.service-now.com

       now-sdk auth save devuser1 --type basic --default true

   Nota:  
   Using the `npx` command installs the ServiceNow SDK in your application directory instead of globally.
6. Respond to the following series of prompts.  
   {#authenticate-instance-basic-auth__table_ivh_lzn_pdc__entry__2}

   | Prompt | Response |
   |-|-|
   | Type of authentication to use | Select basic. |
   | Alias for these credentials | Enter an alias for your credentials and the instance. The alias can be used for authentication with the `init`, `transform`, `dependencies`, and `install` commands. |
   | The username to authenticate with the instance | Enter your username for the instance. You must be assigned the admin role. |
   | The password to authenticate with the instance | Enter your password. |
   [ ]

   {#authenticate-instance-basic-auth__table_ivh_lzn_pdc}
7. At the prompt, enter the target instance URL.
8. At the prompt, enter your ServiceNow user name.  
   You must be assigned the admin role.
9. Enter your password.

## Resultado

The alias and credentials are stored in the device keychain or credential manager on your system and are set as the default credentials.

## O que Fazer Depois

Add an application to your local system with the ServiceNow SDK.
