I have a IT type question??

When I checked in google, it said my phone had accessed my account and another iPhone as well. So I clicked don’t recognize because I’m pretty sure I haven’t logged in on any other devices. I’ve had my phone for over a year now.

So anyway, I came up with a really long password and changed it. I might even change it again, idk? Anyway..

Should I be concerned? Or is it okay since I’ve changed my password?

Also, I had to re-login in my iPhone settings. That’s all normal too, right?

I was just getting ready to delete all of my photos from my phone because they’re saved in my google photos app, but now I’m paranoid somethings going on and I’m scared to loose my pictures.

Any help or advice??

Thanks!
