![](https://rtfm.co.ua/wp-content/uploads/2019/09/okta-logo.png)[Okta](https://okta.com) is an Single Sign-On service provider and I’d like to move all our users to the Okta for better management.

The task now will be to create a Gmail mailbox account and Slack community access.

### Okta Gmail app

Register a new account, go to the _Get started_, in the _Use single sign-on_ click on the _Add app_:

Find _Gmail Inbox_ application:

Leave defaults on the next page:

In this current case, I’m configuring a shared mailbox account access which will be used by various users.

Thus, choose the _Users share a single username and password set by administrator_ type, set the _Email_ type in the в _Application username format_ and configure username and password:

Ready:

### Application assignment

In the _Assignments,_ you can specify which application will be available for user/groups.

Chose the _All users_ access here for the mailbox created above:

Check the access – go to the _My applications_:

### Chrome Okta plugin

### Slack

Similarly to the Gmail application but in contrast to the Gmail account – for the Slack application each user will have to configure login-password by himself.

Add another one _App_:

Chose its name, in the _Domain_ – specify the Slack’s community name without _slack.com_, i.e. if your Slack called _example.slack.com_ – then set the only _example_ here_:_

Chose the _User sets username and password_:

Go to the _Applications_, click on the _Edit_:

And set your Slack’s credentials:

Done.
