If you want to simply have an additional or new npub, use the one-click login. That is saved locally and can be reused. That gives you a profile event and username, standard lists, etc. You can also switch keys at Point of Publish (PoP). The anon key is generated on PoP. Anon mode generates a new keypair for every publish. 🫥 For when what you have to say is more important than who says it. It do be like that, sometimes.
