I forgot my screentime password how can I reset it

Unfortunately you can't reset that code. You have 3 choices:

A) Remember your ScreenTime (you can make infinite attempts to enter it

B) Cohabit with the restrictions you (or someone else) set up in ScreenTime

C) Restore your device to factory settings, and, in the end, set it up as new (without restoring your eventually previously created backup, since it contains that code):--> Restore your iPhone, iPad, or iPod to factory settings - Apple Support

Rules are (valid not only on iPhones but on all devices): No backup = No recovery.

That being said, if you don't have a computer, you have two choices:

borrow one from your friends

or

ask for help at an Apple Store or Authorized Service Provider:--> Apple – Location Selector

So, hold on. I won’t be able to restore photos and songs I’ve made? Or just Apple personal options.

No. The one thing you can do is to purchase iCloud Plan and load all of the stuff to iCloud.

And can this factory reset he done on my iPhone? Ok , but what will I not be able to do if use just iphone

Depending on what restrictions are now enabled on your iPhone.

I have google and iCloud so my things probably going to be there I just want to use my iPhone. Is there any definite no-no’s to that way cerverning my original drawings and songs
