When creating a wallet, a master key with a mnemonic of 24x words is automatically generated.

In order to not reveal your main public key, you can create an unlimited number of additional ones. 

They will all be stored in Key Storage.

How to use Key Storage:

1. Click on the 3 dots at the top right

2. Select Key Storage

3. Click Create

4. Think of a name for the key and click Generate

5. Set a local password for the new key

Now you can see the new key in the general list!

Click Import existing to add the existing key to the wallet.
