Manage users with built-in authentication

MySQL  |  PostgreSQL  |  SQL Server

This page describes how to enable and use Cloud SQL built-in authentication.

For an overview, seeCloud SQL built-in database authentication.

Before creating users

  1. Create a Cloud SQL instance. For more information, seeCreate instances.
  2. Enable password policies for the instance. For more information, seeInstance password policies.
  3. If you plan to use your database's administrative client to manage users,then do the following:

    1. Connect the client to your instance.SeeConnection options for external applications.

    2. Configure the default user on the instance by setting the password.SeeSet the password for the default user account.

Set the password for the default user account

When you create a new Cloud SQL instance, you must set a password for thedefault user account before you can connect to the instance.

For Cloud SQL for MySQL, the default user isroot@% This signifies a database user with a username ofroot which can connect from any host (@%).

Console

  1. In the Google Cloud console, go to theCloud SQL Instances page.

    Go to Cloud SQL Instances

  2. To open theOverview page of an instance, click the instance name.
  3. SelectUsers from the SQL navigation menu.
  4. Find theroot user and then selectChange password from the more actions menuMore actions icon..

    Consider the listed stipulations for the password, which are derived from thepassword policy set for the instance.

  5. Provide a strong password that you can remember and clickOK.

gcloud

Use thegcloud sql users set-password command as follows to set the password for the default user.

ReplaceINSTANCE_NAME with the name of the instance before running the command.

gcloudsqlusersset-passwordroot\--host=%\--instance=INSTANCE_NAME\--prompt-for-password

REST v1

To update the password for the default user account, use a PUT request with the users:update method.

Before using any of the request data, make the following replacements:

  • project-id: Your project ID
  • instance-id: The desired instance ID
  • password: The password for the user

HTTP method and URL:

PUT https://sqladmin.googleapis.com/v1/projects/project-id/instances/instance-id/users?name=root&host=%25

Request JSON body:

{  "name": "root",  "password": "password"}

To send your request, expand one of these options:

curl (Linux, macOS, or Cloud Shell)

Note: The following command assumes that you have logged in to thegcloud CLI with your user account by runninggcloud init orgcloud auth login , or by usingCloud Shell, which automatically logs you into thegcloud CLI . You can check the currently active account by runninggcloud auth list.

Save the request body in a file namedrequest.json, and execute the following command:

curl -X PUT \
-H "Authorization: Bearer $(gcloud auth print-access-token)" \
-H "Content-Type: application/json; charset=utf-8" \

Create a user

Aftersetting up the default user account, you can create other users.

Note: Cloud SQL for MySQL 8.0 usesmysql_native_password as the defaultauthentication plugin for new users instead ofcaching_sha2_password. .However, Cloud SQL for MySQL 8.4 usescaching_sha2_password for thedefault authentication plugin for new users. For moreinformation, seeMySQL authentication.

Console

  1. In the Google Cloud console, go to theCloud SQL Instances page.

    Go to Cloud SQL Instances

  2. To open theOverview page of an instance, click the instance name.
  3. SelectUsers from the SQL navigation menu.
  4. ClickAdd user account.

    In theAdd a user account to instanceinstance_name page, you can choose whether the user authenticates with the built-in database method (username and password) or as anIAM user.

  5. SelectBuilt-in authentication (the default) and add the following information:
    • AUser name.
    • Optional. APassword. Provide a strong password that you can remember.
    • Optional. Theuser password policy.
    • In theHost name section, the default isAllow any host, which means that the user can connect from any IP address. Optionally, selectRestrict host by IP address or address range and enter an IP address or address range in theHost section. The user can then connect only from the IP address or addresses specified.
  6. ClickAdd.

Users created on instances using MySQL 8.0 or later and Cloud SQL's authentication method are granted thecloudsqlsuperuser role automatically and have the following privileges associated with this role:CREATEROLE,CREATEDB, andLOGIN.

Users created on instances using MySQL 5.7 and Cloud SQL's authentication method are granted all privileges except forFILE andSUPER automatically. If you need to change the privileges for these users, then use theGRANT orREVOKE command in themysql client.

For more information about these user accounts and privileges, see Other MySQL user accounts.

gcloud

To create a user, use thegcloud sql users create command.

Replace the following:

  • USER_NAME: The user name.
  • HOST: The user's host name as a specific IP address, address range, or any host (%).
  • INSTANCE_NAME: The name of the instance.
  • PASSWORD: The password for the user.
gcloudsqluserscreateUSER_NAME\--host=HOST\--instance=INSTANCE_NAME\--password=PASSWORD

Users created on instances using MySQL 8.0 or later and Cloud SQL's authentication method are granted thecloudsqlsuperuser role automatically and have the following privileges associated with this role:CREATEROLE,CREATEDB, andLOGIN.

Users created on instances using MySQL 5.7 and Cloud SQL's authentication method are granted all privileges except forFILE andSUPER automatically. If you need to change the privileges for these users, then use theGRANT orREVOKE command in themysql client.

For more information about these user accounts and privileges, see Other MySQL user accounts.

User name length limits are the same for Cloud SQL as foron-premises MySQL; 32 characters for MySQL 8.0 and later, 16 characters forearlier versions.

When you create a user, you can adduser password policy parameters.

Note: If you use thegcloud sql users create command to create a user, Cloud SQL doesn't check to see if the user exists. If a user with the same name exists, the command overwrites the user.

Terraform

To create a user, use aTerraform resource.

resource "random_password" "pwd" {  length  = 16  special = false}resource "google_sql_user" "user" {  name     = "user"  instance = google_sql_database_instance.instance.name  password = random_password.pwd.result}

Apply the changes

To apply your Terraform configuration in a Google Cloud project, complete the steps in the following sections.

Prepare Cloud Shell

  1. LaunchCloud Shell.
  2. Set the default Google Cloud project where you want to apply your Terraform configurations.

    You only need to run this command once per project, and you can run it in any directory.

    export GOOGLE_CLOUD_PROJECT=PROJECT_ID

    Environment variables are overridden if you set explicit values in the Terraform configuration file.

Prepare the directory

Each Terraform configuration file must have its own directory (alsocalled aroot module).

  1. InCloud Shell, create a directory and a new file within that directory. The filename must have the.tf extension—for examplemain.tf. In this tutorial, the file is referred to asmain.tf.
    mkdirDIRECTORY && cdDIRECTORY && touch main.tf
  2. If you are following a tutorial, you can copy the sample code in each section or step.

    Copy the sample code into the newly createdmain.tf.

    Optionally, copy the code from GitHub. This is recommended when the Terraform snippet is part of an end-to-end solution.

  3. Review and modify the sample parameters to apply to your environment.
  4. Save your changes.
  5. Initialize Terraform. You only need to do this once per directory.
    terraform init

    Optionally, to use the latest Google provider version, include the-upgrade option:

    terraform init -upgrade

Apply the changes

  1. Review the configuration and verify that the resources that Terraform is going to create or update match your expectations:
    terraform plan

    Make corrections to the configuration as necessary.

  2. Apply the Terraform configuration by running the following command and enteringyes at the prompt:
    terraform apply

    Wait until Terraform displays the "Apply complete!" message.

  3. Open your Google Cloud project to view the results. In the Google Cloud console, navigate to your resources in the UI to make sure that Terraform has created or updated them.
Note: Terraform samples typically assume that the required APIs are enabled in your Google Cloud project.

Delete the changes

To delete your changes, do the following:

  1. To disable deletion protection, in your Terraform configuration file set thedeletion_protection argument tofalse.
    deletion_protection =  "false"
  2. Apply the updated Terraform configuration by running the following command and enteringyes at the prompt:
    terraform apply
  1. Remove resources previously applied with your Terraform configuration by running the following command and enteringyes at the prompt:

    terraform destroy

mysql Client

To set a user password policy, at themysql prompt, use the followingALTER USER statement:

ALTERUSERUSER_NAMEFAILED_LOGIN_ATTEMPTSALLOWED_FAILED_ATTEMPTSPASSWORDEXPIREINTERVALPASSWORD_EXPIRATION_DURATIONDAYPASSWORDREQUIRECURRENT;

Replace the following:

  • USER_NAME: The user name.
  • ALLOWED_FAILED_ATTEMPTS: Optional: The number of times that a user can try the password incorrectly before the account is locked.
  • PASSWORD_EXPIRATION_DURATION: Optional: Specifies the number of days after which the password expires and the user needs to create a new one.

Use thePASSWORD REQUIRE CURRENT option to make it mandatory for users to enter their existing password when attempting to change the password.

User password policy options are supported on Cloud SQL for MySQL 8.0 and later. ThePASSWORD EXPIRE INTERVAL option is also supported on Cloud SQL for MySQL 5.7.

To view the user password policy, seeList users.
