I started using #Keyoxide's custom domain verification feature. Well, it's not exactly a “custom domain” as we usually think of it (i.e. registering our domain to the service). It's a 301 redirect.

My Keyoxide verification link is now: https://youronly.one/?verify=keyoxide

A lot of benefits to this method:

1. If I change my #PGP / #GPG key later, I can go to my domain's DNS setting and update it there.

2. I don't have to update every account and every post with the new Keyoxide link.

3. My domain itself is verified (not just in Keyoxide).

4. Identity recognition. Because, you know, https://im.youronly.one/

5. Branding. Of course! LOL.
