Q: How to reset iPhone

What password doesn't she remember exactly?

The passcode to unlock her screen?

The password to her Apple ID?

Before you can use it your friend needs to follow this:

What to do before selling or giving away your iPhone, iPad, or iPod touch - Apple Support

Which password? The password to unlock the phone when it goes to sleep? For that, you restore the phone as new using iTunes. If you mean the Apple ID password that you're asked for during set up, without that password, the phone can't be activated. You'll need to get the password from whoever set it up.

Depending on what is not remembered they may be ways around this.

But you have not told us what they don't remember?

If she forgot her Apple ID, she can try to sue http://iforgot.apple.com and try to recover her Apple ID and password.

If she forgot the passcode to unlock the screen, then the iPhone can be restored without it.

If she forgot something else you need to tell us what it is she forgot.

Saying she forgot all the information entered when it was setup, is like saying they have amnesia and don't remember half their life.

In all honesty, this sounds more like a phone that was found, or bought from someone that was not the owner, than anything else.
