Enabling OAUTH2 Authentication

To enable OAUTH2 authentication for pgAdmin, you must configure the OAUTH2 settings in the config_local.py or config_system.py file (see the config.py documentation) on the system where pgAdmin is installed in Server mode. You can copy these settings from config.py file and modify the values for the following parameters:

Parameter Description
AUTHENTICATION_SOURCES

The default value for this parameter is internal. To enable OAUTH2 authentication, you must include oauth2 in the list of values for this parameter. you can modify the value as follows:

  • [‘oauth2’, ‘internal’]: pgAdmin will display an additional button for authenticating with oauth2
OAUTH2_NAME The name of the Oauth2 provider, ex: Google, Github
OAUTH2_DISPLAY_NAME Oauth2 display name in pgAdmin
OAUTH2_CLIENT_ID Oauth2 Client ID
OAUTH2_CLIENT_SECRET Oauth2 Client Secret
OAUTH2_TOKEN_URL Oauth2 Access Token endpoint
OAUTH2_AUTHORIZATION_URL Endpoint for user authorization
OAUTH2_SERVER_METADATA_URL Server metadata url for your OAuth2 provider
OAUTH2_API_BASE_URL Oauth2 base URL endpoint to make requests simple, ex: https://api.github.com/
OAUTH2_USERINFO_ENDPOINT User Endpoint, ex: user (for github) and useinfo (for google)
OAUTH2_SCOPE Oauth scope, ex: ‘openid email profile’. Note that an ‘email’ claim is required in the resulting profile.
OAUTH2_ICON The Font-awesome icon to be placed on the oauth2 button, ex: fa-github
OAUTH2_BUTTON_COLOR Oauth2 button color
OAUTH2_USERNAME_CLAIM
The claim which is used for the username. If the value is empty
the email is used as username, but if a value is provided, the claim has to exist. Ex: oid (for AzureAD)
OAUTH2_AUTO_CREATE_USER
Set the value to True if you want to automatically
create a pgAdmin user corresponding to a successfully authenticated Oauth2 user. Please note that password is not stored in the pgAdmin database.

Redirect URL

The redirect url to configure Oauth2 server is http://<pgAdmin Server URL>/oauth2/authorize

Master Password

In the multi user mode, pgAdmin uses user’s login password to encrypt/decrypt the PostgreSQL server password. In the Oauth2 authentication, the pgAdmin does not store the user’s password, so we need an encryption key to store the PostgreSQL server password. To accomplish this, set the configuration parameter MASTER_PASSWORD to True, so upon setting the master password, it will be used as an encryption key while storing the password. If it is False, the server password can not be stored.

Login Page

After configuration, on restart, you can see the login page with the Oauth2 login button(s).
