What to do if you forgot your iphone password?

Question

iOS

There are iphone 11, ios 14 (some kind). I changed the unlock password, I made a mistake by one letter (yes, in repetition too). What are the ways to unlock the phone? There is no Macbook, there are no synchronized applications (iTunes, iCloud, etc.), I don’t rummage in iPhones at all. Is it possible to do this without formatting the phone? If not, are there ways in the future to get the data back?

Answer 1

Ask the owner.
If you really are the owner, then come to any authorized Apple service center, show them the purchase receipt for the phone and hand it in for a reset.
There are no more ways, how and what you are going to format is not entirely clear.
