It is extremely easy to use.​

Once installed, you will need to set group permissions to use the switch account feature.

How it works?​

Just link as many accounts as you want.
Visitor menu –> Add account
Now you can always switch between these accounts.

Not only for admins​

The add-on uses the standard XenForo login system when linking an account, so the user will not be able to add an account that does not belong to him.
