Dear Student by reading the above question I understand You need a clear idea to visualise the above scenario.Please go through the details given below It will surely help you to understand each of the following steps involved:-

The concept Involved in answering your question is SSO.

How does single sign-on work?

What is single sign-on?

Single sign-on (SSO) is a validation technique that empowers clients to safely verify with numerous applications and sites by utilizing only one lot of certifications.

How accomplishes SSO work?

SSO works dependent on a trust relationship set up between an application, known as the specialist organization, and a personality supplier, as OneLogin. This trust relationship is frequently founded on a declaration that is traded between the character supplier and the specialist organization. This testament can be utilized to sign character data that is being sent from the personality supplier to the specialist co-op so the specialist organization realizes it is originating from a confided in source. In SSO, this personality information appears as tokens which contain recognizing pieces of data about the client like a client's email address or a username.

The login stream normally resembles this:

A client peruses to the application or site they need admittance to, otherwise known as, the Service Provider.

The Service Provider sends a symbolic that contains some data about the client, similar to their email address, to the SSO framework, otherwise known as, the Identity Provider, as a feature of a solicitation to validate the client.

The Identity Provider first verifies whether the client has just been validated, in which case it will allow the client admittance to the Service Provider application and jump to stage 5.

In the event that the client hasn't signed in, they will be incited to do as such by giving the certifications needed by the Identity Provider. This could basically be a username and secret key or it may incorporate some other type of validation like a One-Time Password (OTP).

When the Identity Provider approves the accreditations gave, it will send a token back to the Service Provider affirming an effective verification.

This token is gone through the client's program to the Service Provider.

The symbolic that is gotten by the Service Provider is approved by the trust relationship that was set up between the Service Provider and the Identity Provider during the underlying arrangement.

The client is conceded admittance to the Service .Provider.

At the point when the client attempts to get to an alternate site, the new site would must have a comparative trust relationship arranged with the SSO arrangement and the verification stream would follow similar advances.

What is a SSO token?

A SSO token is an assortment of information or data that is passed starting with one framework then onto the next during the SSO cycle. The information can basically be a client's email address and data about which framework is sending the token. Tokens must be carefully finished paperwork for the symbolic collector to check that the token is originating from a confided in source. The testament that is utilized for this advanced mark is traded during the underlying setup measure.

Is SSO secure?

The response to this inquiry is "It depends."

There are numerous reasons why SSO can improve security. A solitary sign-on arrangement can streamline username and secret key administration for the two clients and overseers. Clients at this point don't need to monitor various arrangements of certifications and can essentially recollect a solitary more perplexing secret word. SSO frequently empowers clients to simply gain admittance to their applications a lot quicker.

SSO can likewise eliminate the measure of time the assistance work area needs to go through on helping clients with lost passwords. Managers can midway control necessities like secret key multifaceted nature and multifaceted confirmation (MFA). Directors can likewise more rapidly give up login benefits in all cases when a client leaves the association.

Single Sign-On has a few downsides. For instance, you may have applications that you need to have secured somewhat more. Therefore, it is imperative to pick a SSO arrangement that enables you to, state, require an extra confirmation factor before a client signs into a specific application or that keeps clients from getting to specific applications except if they are associated with a protected organization.

How is SSO executed?

The points of interest on how a SSO arrangement is executed will vary contingent upon what precise SSO arrangement you are working with. Be that as it may, regardless of what the particular advances are, you have to ensure you have define clear destinations and objectives for your usage. Ensure you answer the accompanying inquiries:

Is it true that you are searching for an On Prem arrangement or a Cloud Based arrangement?

Will this arrangement have the option to develop with your organization and your needs?

What highlights would you say you are searching for to guarantee just believed clients are signing in? MFA, Adaptive Authentication, Device Trust, IP Address Whitelisting, and so on?

What frameworks do you have to coordinate with?

Do you need API access?

What makes a genuine SSO framework?

It's imperative to comprehend the contrast between single sign-on and secret key vaulting or secret phrase administrators, which are in some cases alluded to as SSO which can mean Same Sign-on not Single Sign-on. With secret word vaulting, you may have the equivalent username and secret phrase, yet they should be entered each time you move to an alternate application or site. The secret word vaulting framework is basically putting away your certifications for all the various applications and embeddings them when vital. There is no trust relationship set up between the applications and the secret word vaulting framework.

With SSO, which means Single Sign-On, after you're signed in through the SSO arrangement, you can get to all organization endorsed applications and sites without signing in once more. That incorporates cloud applications just as on-prem applications, regularly accessible through a SSO gateway (additionally called a login entrance).
