Could we get an overview of nostr key storage using Passport? I got an inquiry from nostr:nprofile1qqsdvckpplxm9wvsevfln6f573ucmx7snyvhn5p64gzjejmy0rgrntcpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhszxmhwden5te0wa5x2ct59e5xzurs096xzan9wfhzucm09uq3kamnwvaz7tmjv4kxz7fwdehhxarjwpkx2cnn9e3k7mf0acz0u5 about how I manage/create my nostr keys. It's so simple, easy, awesome yet he had no idea. Maybe a presenter can incorporate some of this content at nostr:nprofile1qqs8mez352yxc2r9yt838c9f0sfs86ey0ygh7e996qspx773957u95gpzemhxue69uhkummnw3ex2mrfw3jhxtn0wfnj7ypspnl?
