Does nos2x need the hex key or the nsec one ? It doesn’t appear to do anything with a few test keys.
**Attention new plebs that joined Nostr this evening:**
While you're trying out new clients, don't just go and enter your private key everywhere. This is like the private key for your bitcoin. You want to keep it safe.
There are extensions that can help with this. Either [nos2x](https://chrome.google.com/webstore/detail/nos2x/kpgefcfmnafjgpblomihpgmejjdanjjp) or [GetAlby](https://chrome.google.com/webstore/detail/alby-bitcoin-lightning-wa/iokeahhehimjnekafflcihljlcjccdbe).
Once you have these installed, visit metadata.nostr.com and setup your profile picture and your name.
When you're ready to setup your NIP-05 ID, you can either do this yourself or use the service that #[0] and I setup. Visit nostrplebs.com to learn more.
