While you're trying out new client, 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's an extension 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). These extensions essentially hold your private key and  help you sign transactions, so you don't have to enter them directly into a website. Once you have these installed, visit metadata.nostr.com and setup your profile picture and your NIP-05 ID. If you're using the Damus app, this doesn't apply to you. Enjoy!

Want a NIP-05 ID? nostrplebs.com can help you out with that. 🤝
