OpenID is an open standard of a decentralized authentication system that allows the user to create a single account for authenticating to multiple unrelated Internet resources.

To set up OpenID authorization on the Picvario website:

Configure settings on Google:

1. Go to https://console.developers.google.com/apis/credentials using your organization's administrator account.
2. Create a new web application (for example, named Picvario).
3. Get the ClientID and Client Secret in the control panel:
   
   
4. Add the following address to the list of authorized URIs: 

 <site_url>/api/v1/users/oidc/callback

Configure settings on Picvario:

1. Copy the environment variable from frontend SITE_BASE_URL=< some url >.
2. In the tenant's Options ( https://<tenant-name>.<site_url>/admin/options/option/) or in hosted versions ( https://<site_url>/admin/options/option/ ), create the parameter: 

   OPENID_AUTH_ENABLED

After the parameter is added, 11 more parameters will be created AUTOMATICALLY. You will need to change their values to:

	KEY	VAL	PUBLIC
	OIDC_TOKEN_USE_BASIC_AUTH	True
	OIDC_RP_SIGN_ALGO	RS256
	OIDC_RP_SCOPES	email profile openid
	OIDC_RP_CLIENT_SECRET	(from Google)
	OIDC_RP_CLIENT_ID	(from Google)
	OIDC_OP_USER_ENDPOINT	https://openidconnect.googleapis.com/v1/userinfo
	OIDC_OP_TOKEN_ENDPOINT	https://oauth2.googleapis.com/token
	OIDC_OP_JWKS_ENDPOINT	https://www.googleapis.com/oauth2/v3/certs
	OIDC_OP_AUTHORIZATION_ENDPOINT	https://accounts.google.com/o/oauth2/v2/auth

IMPORTANT! The Public property of all of the above-mentioned options must have the False value! (set by default)

If you want to allow anonymous users to view assets, use ALLOW_ANONYMOUS_USERS = True. This parameter must be public (Public = True) regardless of the value of the parameter itself.

To allow authorization BOTH via Gsuite AND via Picvario, the MULTI_AUTH parameter is used. This parameter is also public (Public = True).

MULTI_AUTH=True/False 

• parameter that determines whether authentication is possible using several available methods: standard and via OpenID. In the UI, this option is displayed as a page with the standard login and password fields and an additional button at the bottom: "Sign in via corporate account". When the value is False, the authentication option is determined by the OPENID_AUTH_ENABLED.

Sequence of public key search for token verification / Option Priority:

1. OIDC_RP_IDP_SIGN_KEY_PATH

2. OIDC_RP_IDP_SIGN_KEY

3. OIDC_OP_JWKS_ENDPOINT

If errors such as

SuspiciousOperation

or

JWS token verification

failed appear, make sure there is no conflict between these options. 

Only 

OIDC_OP_JWKS_ENDPOINT

should be specified for GSuite. Other options in this list should be left empty!
