Hi. When setting up my own domain to be used

in my mail addresses, my email provider gave me two secret strings for some kind of verification. Something like
abc123.mydomain.com TXT xyz789
But I accidentally set the TXT value to my root domain (e.g. mydomain.com) instead of this secret subdomain. I quickly fixed this, but I wonder... Is it a security issue if someone else knows this generated subdomain and its TXT value?

No

How does this verification work? I searched online and found two things: SPF and DKIM. Which one should I read about?
