This tutorial shows you how to manipulate the path level to create many accounts on your Ledger Nano S. Dive deep on path levels here.
Visit the Stellar Account Viewer, connect your Ledger Nano S to your computer, unlock the device, and open the Stellar app on the device.
On the Stellar Account Viewer below “Connect Ledger Nano S”, uncheck “Use default account”.
A text box will appear. In that text box, you should see “ 44'/148'/0' ”, which is called a path level. The “44” stands for the “purpose” level of the path, “148” stands for “coin type”, and “0” stands for “account”. The value “0” for the account level represents your default account, and you can have multiple accounts on your Ledger Nano S by changing this number.
Change the account path level from “0” to “1” then click “Sign in with Ledger”. This will generate a new “1” account ID that needs to be activated.
Sign out of the “0” account and back into the “1” account to see your newly created secondary Ledger Nano S account.
