If for some reason you need to use multiple Discord accounts at once, managing them flexibly is also an issue to consider. Discord's web and desktop sessions allow users to add all their accounts to the app, and then switch between them easily. Let's find out right away.
(Note: At the time of writing, Discord's mobile app does not yet offer the option to manage multiple accounts.)
Step 1: Add a secondary account to Discord
The first thing you’ll need to do is add your secondary Discord account to the app. To do this, launch the Discord desktop app, or open any browser and go to the Discord website.
Once the Discord interface opens, in the bottom left corner, click your profile icon and select Switch Accounts > Manage Accounts .

On the “ Manage Accounts ” window that opens, select “ Add an Account ”.

You will be taken to the “ Add Account ” window . Here, click on the “ Email or Phone Number ” field and enter the email or phone number of the sub-account. Click on the “ Password ” field and enter the password of the sub-account you want.
Then select “ Continue ”.

That's it. Your secondary account is now added to Discord, and you can switch to it whenever you want.
Step 2: Switch between multiple accounts in Discord
To switch between multiple accounts in Discord, first launch the Discord desktop app, or open any browser and visit the Discord website.
Once the Discord interface opens, in the bottom left corner, click on your profile icon and hover your cursor over “ Switch Accounts ”.

From the expanded “ Switch Accounts ” menu, select the account you want to use.

After selecting an account, Discord will reload and take you to your selected account.
That's all you need to do to switch multiple Discord accounts at once.
