I will make a prediction. Once you get the domain and set it up, the images will still not work. Are you using an external proxy? I was battling this for days, Lemmy backend refused to create thumbs for my local images, federated content worked great. IF you get this issue, send me a message, I found a workaround.
Start setting up passkeys where available, that is the safest and easiest way, I store mine on my selfhosted vaultwarden but you could use other ways. As long as the devices you use are secure, no passwd leaks, spoofing attempts or phishing can threaten you.
