Excuse my English, I'm kind of rushing things.

So my dad just fixed our old iPhone. This was bought in 2013 but has been broken in 2018. Activation lock seems to be the problem, we already forgot two things: the password of the Apple ID and the passcode connected to it.

Is this any way how to bypass this and finally gain access to it again? I still know the iCloud account and the phone number assigned to it, but whenever we try doing so using this link (iforgot.apple.com/password/verify/appleid) and borrowing a friend's iPad, they kept asking about the passcode and/or the verification code sent to the iCloud account.

It's been a loop so I hope there is any way for this to be fixed. Thanks!
