Did I damage my iPhone's built in security?

Question

Bought an iPhone recently.
I was just playing around with it and like an idiot I went and erased all contacts and settings on my iPhone.
Setting> General>Reset>Erase all content and settings
When I turned my phone  back on, it was like it was starting at the very start of initiating itself.
The first prompt was about what language I wanted and so forth, so it was like it was just brand new.
I had taken it to an apple store and they set me back up.
But now I’m concerned if I compromised the internal built in security of my phone by hitting that  Erase all content and settings button
Like did I erase any of the built n safety/security functions?
I know people can “jail break” their phone and I hop I didn’t do that on accident.
I just want to make sure that I did not compromise the phones built security measures.

No, you did no harm at all.  All you did was erase anything, other than the default, that you had added or installed.  You literally did return it to the same state it was in when new, right out of the box - a full reset.
